Best Knowledge Management Software in 2026
Notion ranks first in knowledge management software, followed by Slite and Nuclino. Knowledge management software gives a company one searchable, owned home for processes, policies and know-how, so employees stop asking the same questions.
The top three

1. NotionFirst because one workspace holds the wiki, the project notes and the databases a 50 to 1,000 person company needs, at a published price with a free plan.
2. SliteSecond because it is built for one job, a team knowledge base that stays current, and publishes a clear per-member price with a trial.
3. NuclinoThird because it is a quick, clean shared workspace from a German company, with a free plan and per-user tiers, but with fewer governance tools.What is knowledge management software?
Knowledge management software is a system where a company writes down how it works, keeps that material current and lets employees find it quickly. It usually combines an editor, a page structure, search, permissions and a way to confirm that content is still correct. Newer products add AI answers that cite the source page and deliver them inside chat tools.
How we ranked these
Most companies do not lack knowledge. They lack a place where the current version of it can be found in under a minute.
Onboarding steps sit in a shared drive, the refund policy lives in a chat thread, and the person who knew how the billing process works left last spring. Knowledge management software gives that material one home, an owner per page and a search that people trust.
This ranking looks at tools for internal use at companies of 50 to 1,000 people: wikis, team knowledge bases and documentation platforms that employees read every week. Customer help centers are out of scope, so Document360 is judged on its internal use only.
Each product is measured on the five tests below: how quickly a first useful wiki exists, what a team of 200 pays, whether content leaves cleanly, how much the vendor controls your exit, and which kind of company gets the most from it. The mix includes lightweight wikis, governed knowledge platforms and two suite products from large vendors.
The order is the verdict, and there is no score. We also asked a practical question for every tool: what happens in month eight, when the first enthusiasm has faded and half the pages are out of date.
Tools that nudge owners to confirm content rank above those that rely on goodwill.
Setup: how fast does a useful wiki exist?
A usable first wiki takes an afternoon in a lightweight tool and weeks in a governed platform. We asked what it takes to import existing documents, build a first page tree and let thirty people in with the right permissions. Notion, Slite, Nuclino and Slab start from a blank page and a template library.
Guru, Bloomfire and Document360 usually involve a sales conversation and an onboarding plan first. SharePoint can be live on day one for a Microsoft 365 company, but a good structure needs design.
Imports from Google Docs, Word and other wikis shorten everything, and single sign-on matters for a company above a few hundred people. We rank products lower when the administrator needs training in the vendor's own vocabulary.
The real price: seats, tier gates and quote walls
Of the eleven products, eight publish plans or prices on their own site and three are quote only. Published prices run from free for small teams up to about $20 a member a month, and the figure that matters is a 200-person bill with single sign-on switched on. Some vendors put SSO, SCIM and audit logs only on the top tier.
Others, such as Tettra, require a minimum of ten seats, and Outline prices cloud in size bands with a jump at 11 and 101 members. Guru, Bloomfire and Document360 do not publish numbers at all, so a budget needs a quote.
We note where we could not confirm an amount.
Getting your data out: pages, history and attachments
Test the exit door before you build the house. After two years a wiki holds thousands of pages, their edit history, comments and attachments, and a tool that exports only flat text loses most of the value. Ask for a trial export in a standard format such as Markdown or HTML and check whether links between pages, page owners and attachments survive.
Outline has a Markdown editor and public source code, which helps portability. Several vendors here offer an API on their site, and some list an MCP server for AI tools.
Confirm the API is open on your plan, since vendors often reserve it for upper tiers, and ask where data is hosted.
Independence from the vendor: suites, bundles and ownership
Knowledge tools are often the thin end of a larger sale. Confluence is tied to the Atlassian family, so its best features lean on Jira, and SharePoint comes inside Microsoft 365, which makes it cheap to start and hard to leave. Document360 sits under a parent company, Kovai.co, which says it is headquartered in London.
Guru and Bloomfire now describe themselves as AI knowledge layers, which shows how quickly a category can drift away from what you bought. Ask for a price cap at renewal, a written exit clause and a statement on what happens to your content if the product changes direction.
Open source Outline is the only product here with a self-hosted route.
Who it's for: wikis, governed platforms and suites
The eleven products fall into three groups. Lightweight workspaces (Notion, Slite, Nuclino, Slab, Tettra, Outline) suit companies that want people writing pages this week and care more about adoption than process. Governed or documentation platforms (Guru, Document360, Bloomfire) suit organizations where wrong answers cost money, such as support, sales enablement and regulated teams.
Suites (Confluence, SharePoint) suit companies that already live inside Atlassian or Microsoft 365 and accept the admin work. Pick the group by asking who will own page quality: everyone, a small editorial team, or an administrator.

Global vendorWikiFlexible
Why #1: First because one workspace holds the wiki, the project notes and the databases a 50 to 1,000 person company needs, at a published price with a free plan.
- Best for
- Companies wanting one flexible workspace
- Pricing
- Per user / month
- Free option
- Free plan
- Headquarters
- United States
- Key features
- Pages and wikis, Databases, Templates, Page permissions, Search
- Falls short
- Notion does not force structure, so wikis grow into sprawling page trees where the same policy exists in three versions.
- Wrong for
- Wrong for teams that want strict editorial control, mandatory review cycles or a locked structure.
Full assessment of Notion
Notion earns the top place because it is the product most buyers can start using the same afternoon and still be using in three years. A page tree gives you a wiki, a database turns a list of processes into something filterable, and the free plan lets a pilot team prove the habit before anyone signs a contract.
Prices are published, the tiers are easy to compare, and a large library of community templates covers onboarding handbooks, meeting notes and policy pages. For a company without a dedicated knowledge manager, that low barrier decides the ranking.
Where it falls short
Notion does not force structure, so wikis grow into sprawling page trees where the same policy exists in three versions. Search gets noisier as the workspace ages, and page-level permissions take planning once HR, finance and legal content share a workspace.
Ownership and review dates are available but optional, which means nobody is chased when a page goes stale unless you set that rule yourself.
Wrong for
Wrong for teams that want strict editorial control, mandatory review cycles or a locked structure. A governed knowledge base such as Guru or a documentation tool such as Document360 enforces process better.

Global vendorWikiAI search
Why #2: Second because it is built for one job, a team knowledge base that stays current, and publishes a clear per-member price with a trial.
- Best for
- Teams wanting a tidy, low-effort wiki
- Pricing
- Per user / month
- Free option
- Free trial
- Headquarters
- United States
- Key features
- Team knowledge base, AI search with citations, Agent that flags outdated pages, Slack and GitHub connectors, SSO and SCIM
- Falls short
- Slite is narrower than Notion or Confluence: it is a knowledge base, not a place to build trackers or run projects.
- Wrong for
- Wrong for teams that want one tool for wiki, tasks and databases, or that need a free tier to keep running indefinitely.
Full assessment of Slite
Slite takes second place because it starts from the question a wiki owner actually has: which of these pages is still right. Its agent flags outdated documentation and drafts updates for the page owner to approve, and search answers cite the pages they used.
Pricing is stated in dollars per member, and the vendor lists SSO, SCIM and audit logs along with EU hosting and SOC 2 Type II statements. A company of a few hundred people can set it up without an administrator learning a new vocabulary.
Where it falls short
Slite is narrower than Notion or Confluence: it is a knowledge base, not a place to build trackers or run projects. It has no permanent free plan, only a 14-day trial, and the Enterprise tier is priced on request.
The company address on its privacy page is a mailing address, so buyers who need a verified headquarters should ask.
Wrong for
Wrong for teams that want one tool for wiki, tasks and databases, or that need a free tier to keep running indefinitely. Notion or Nuclino fits those buyers better.
-
German vendorWikiFast search
Why #3: Third because it is a quick, clean shared workspace from a German company, with a free plan and per-user tiers, but with fewer governance tools.
- Best for
- Small to mid-sized teams wanting speed
- Pricing
- Per user / month
- Free option
- Free plan
- Headquarters
- Germany
- Key features
- Shared workspace, Instant search, Templates, Collaborative editing, API
- Falls short
- Nuclino offers fewer governance controls than the dedicated knowledge tools: there is no built-in cycle that makes page owners confirm content is still correct.
- Wrong for
- Wrong for regulated companies that need review workflows and audit trails on every page, and for buyers who want a documentation publishing portal.
Full assessment of Nuclino
Nuclino sits third because it is the lightest product here that still behaves like a proper company wiki. The vendor pitches it as a team's collective brain: items live in a simple structure, search is instant and a basic Free plan lets a team begin without a card.
The provider is a German GmbH with a stated address near Munich, which helps buyers who want a European vendor in a market full of American ones. Setup is measured in hours, not weeks.
Where it falls short
Nuclino offers fewer governance controls than the dedicated knowledge tools: there is no built-in cycle that makes page owners confirm content is still correct. The vendor describes a mix of knowledge and project features, so it is less focused than Slite.
We could not read the plan amounts on the pricing page, so confirm the numbers before budgeting.
Wrong for
Wrong for regulated companies that need review workflows and audit trails on every page, and for buyers who want a documentation publishing portal. Guru or Document360 suit those needs.
-
US-basedVerified answersEnterprise
Why #4: Fourth because it verifies content as it is used and answers in Slack and Teams, but it is quote only and now leads with AI governance.
- Best for
- Companies wanting verified, permission-aware answers
- Pricing
- Quote only
- Free option
- None
- Headquarters
- United States
- Key features
- Content quality checks, Gap detection, Automatic verification, Role-scoped answers with citations, Slack and Teams delivery
- Falls short
- Guru gives no price without a sales conversation and has no free plan or trial on its pricing page.
- Wrong for
- Wrong for teams under about 50 people, and for buyers who want a plain wiki editor with a posted price.
Full assessment of Guru
Guru earns fourth place for the strongest answer to the trust problem in company knowledge. The vendor describes quality checks for conflicting versions, duplicates and stale pages, routing of gaps to experts for review, and answers that are scoped to the asker's role with source citations.
It surfaces knowledge in Slack, Microsoft Teams and a browser extension, which is where support and sales staff already work. SOC 2 Type 2 and audit trails are stated on the vendor's site.
Where it falls short
Guru gives no price without a sales conversation and has no free plan or trial on its pricing page. The homepage is now organized around AI answers and governance, and the classic experience of writing and structuring wiki pages is described in little detail.
Smaller teams can find the package heavier than the problem.
Wrong for
Wrong for teams under about 50 people, and for buyers who want a plain wiki editor with a posted price. Slite or Nuclino are the simpler start.
-
US-basedWikiFree plan
Why #5: Fifth because the wiki is clean and the free plan for ten users is real, yet we could verify less of its feature set than for the products above.
- Best for
- Small teams starting a wiki on a budget
- Pricing
- Per user / month
- Free option
- Free plan
- Headquarters
- United States
- Key features
- Wiki and knowledge base, Document library, Search, Free plan for 10 users, Tiered plans
- Falls short
- The pages we could read gave little product detail, so integrations, security controls and AI features were not confirmed here.
- Wrong for
- Wrong for buyers who must confirm a headquarters address and security certifications before a pilot, and for companies above ten people who want to stay free.
Full assessment of Slab
Slab takes fifth place for pricing that is easy to read: a free plan for up to ten users, then a Startup tier at $6.67 and a Business tier at $12.50 per user a month billed annually. The vendor describes itself as a fully remote company and positions the product as a wiki and knowledge base for organizing and finding documents.
For a team of ten that wants a proper home for its processes without paying, it is a sensible choice.
Where it falls short
The pages we could read gave little product detail, so integrations, security controls and AI features were not confirmed here. The only address in the terms is a copyright-agent notice address, not a stated headquarters.
The free plan ends at ten users, which is the point where most growing companies need to pay.
Wrong for
Wrong for buyers who must confirm a headquarters address and security certifications before a pilot, and for companies above ten people who want to stay free. Outline self-hosted or Notion cover those cases.
-
MajorWikiJira
Why #6: Sixth as a major: spaces, templates and Jira links suit engineering-led companies, yet it asks for more upkeep to stay tidy than the focused tools.
- Best for
- Engineering-led teams already on Jira
- Pricing
- Per user / month
- Free option
- Free plan
- Headquarters
- Australia
- Key features
- Spaces and pages, Templates, Page permissions, Search, Jira integration
- Falls short
- Confluence needs a gardener.
- Wrong for
- Wrong for companies without a Jira habit, for HR and operations teams that want a simple handbook, and for buyers wary of suite lock-in.
Full assessment of Confluence
Confluence is the default wiki in many companies because it arrives with Jira, and the vendor's page lists live docs, whiteboards, databases and a large template library across functions including HR and finance. Status markers and automation flag outdated pages, and Rovo can draft and summarize.
For a development organization that already tracks work in Jira, linking specs to tickets is a real saving, and the free plan lets a small group begin.
Where it falls short
Confluence needs a gardener. Without a space structure and an owner, spaces multiply and search returns old pages beside current ones.
Non-technical staff often find the editor and navigation heavier than in lighter tools, and the best experience depends on other Atlassian products and paid marketplace apps.
Wrong for
Wrong for companies without a Jira habit, for HR and operations teams that want a simple handbook, and for buyers wary of suite lock-in. Slite or Nuclino are easier to adopt.
-
US-basedSlackQ&A
Why #7: Seventh because Slack-based questions and page verification are neat, but the product is narrow and the Scaling tier needs ten paid users.
- Best for
- Slack-centered teams of 10 or more
- Pricing
- Per user / month
- Free option
- Free trial
- Headquarters
- United States
- Key features
- Built-in editor, Kai AI Q&A, Slack bot, Page verification, Knowledge gap detection
- Falls short
- Tettra's scope stops at Q&A and verification: no databases, tasks or rich project views.
- Wrong for
- Wrong for companies that use Microsoft Teams as the main chat tool, and for buyers who want a workspace that also tracks work.
Full assessment of Tettra
Tettra is seventh because it does a small number of things well for teams who talk in Slack. The Slack bot answers questions in channels and direct messages, the AI suggests an expert when no page exists, and pages can be verified and edits approved before they go live.
Imports from Google Docs and Notion lower the cost of moving, and the 30-day trial runs with all features and no card, which is generous.
Where it falls short
Tettra's scope stops at Q&A and verification: no databases, tasks or rich project views. The Scaling tier carries a ten-user minimum, so very small teams pay for seats they do not use, and Enterprise has no published price.
Teams that do not live in Slack get less out of it.
Wrong for
Wrong for companies that use Microsoft Teams as the main chat tool, and for buyers who want a workspace that also tracks work. Notion or Confluence offer that breadth.
-
Open sourceSelf-hostedMarkdown
Why #8: Eighth because it is the open source option with a self-hosting path, yet cloud pricing runs in team-size bands and the free edition is limited.
- Best for
- Teams wanting a self-hosted wiki
- Pricing
- Open source + paid tiers
- Free option
- Open source
- Headquarters
- United States
- Key features
- Markdown editor, Realtime collaboration, Workspace search, Slack integration, Public and private sharing
- Falls short
- The free Community Edition has limited features and no support, and after a 30-day cloud trial the knowledge base turns read-only until you add a payment method.
- Wrong for
- Wrong for teams that want a managed tool with a permanent free cloud tier, and for companies without IT staff to run a self-hosted install.
Full assessment of Outline
Outline takes eighth place because it offers something the others do not: public source code and a self-hosted route, for companies that want to keep the wiki on their own servers. The editor is Markdown-based with slash commands and live collaboration, sharing can be public or private, and there is a Slack integration and an API.
Cloud bands are cheap for mid-size teams, with 11 to 100 members at $79 a month.
Where it falls short
The free Community Edition has limited features and no support, and after a 30-day cloud trial the knowledge base turns read-only until you add a payment method. Cloud bands make price jumps at 11 and 101 members, and over 200 users is quote only.
The company is described as built in New York, but no street address was verified.
Wrong for
Wrong for teams that want a managed tool with a permanent free cloud tier, and for companies without IT staff to run a self-hosted install. Slab or Nuclino offer free tiers.

UK-basedDocumentationQuote only
Why #9: Ninth because it is a capable documentation platform that also serves internal readers, but it is built around help centers and quoted by demo.
- Best for
- Teams with internal and customer docs
- Pricing
- Quote only
- Free option
- None
- Headquarters
- United Kingdom
- Key features
- Collaborative editor, Workflow builder, AI search and chatbot, SSO and SCIM, Analytics

- For an internal-only wiki it is more than most teams need, and the price is a quote after a demo, with no trial mentioned.
- Wrong for
- Wrong for small internal teams that want a posted price and a free plan, and for anyone who does not publish customer documentation.
Full assessment of Document360
Document360 lands ninth in a list about internal knowledge because its strength is publishing documentation. The vendor describes a portal for editors and a site for customers and employees, with workflow approvals, import from PDF and Word, AI search and SSO with SCIM.
Companies that maintain a customer help center and also want employee documentation in the same system will find the editing and review tools mature. The parent, Kovai.co, says it is headquartered in London.
Where it falls short
For an internal-only wiki it is more than most teams need, and the price is a quote after a demo, with no trial mentioned. The product is built for both internal and customer-facing documentation, so some features aim at help centers.
We could not verify a street address for the contracting entity.
Wrong for
Wrong for small internal teams that want a posted price and a free plan, and for anyone who does not publish customer documentation. Slite or Nuclino are lighter.
-
US-basedEnterprise AIQuote only
Why #10: Tenth because its knowledge platform has moved to an enterprise AI layer, sold by quote, which suits fewer buyers than a plain internal wiki.
- Best for
- Large teams wanting an AI knowledge layer
- Pricing
- Quote only
- Free option
- None
- Headquarters
- United States
- Key features
- Enterprise intelligence engine, Persistent semantic memory, Source-traced answers, Conversational AI agent, Content pruning tools
- Falls short
- The page never names employees as the audience, so the internal wiki use is inferred rather than stated.
- Wrong for
- Wrong for companies under a few hundred staff, and for teams that only want a simple internal wiki with a posted price.
Full assessment of Bloomfire
Bloomfire ranks tenth because it has moved away from the plain internal wiki. Its homepage leads with governed context for enterprise AI, while still describing knowledge management tools that prune outdated and redundant content, plus an API-first design with more than 100 connectors for enterprise systems.
For a large organization that wants answers across many sources with traceability back to the original, that is a coherent offer. The privacy policy gives a mailing address in Littleton, Colorado.
Where it falls short
The page never names employees as the audience, so the internal wiki use is inferred rather than stated. There is no published price and no trial, and the headline is now AI governance, which makes a simple document library hard to find.
A small team will find it oversized.
Wrong for
Wrong for companies under a few hundred staff, and for teams that only want a simple internal wiki with a posted price. Notion or Slab are better fits.
-
MajorMicrosoft 365Document-centric
Why #11: Eleventh as a major: many companies already own it inside Microsoft 365, but a usable knowledge base on it needs design and admin effort.
- Best for
- Microsoft 365 shops with admin skills
- Pricing
- Per user / month
- Free option
- None
- Headquarters
- United States
- Key features
- Team sites, Communication sites, Document libraries, Permissions, Search
- Falls short
- A good knowledge base on SharePoint needs site design, navigation planning and an administrator, and the default result is a pile of folders.
- Wrong for
- Wrong for companies without Microsoft 365 skills, and for teams that want a wiki running in a week.
Full assessment of Microsoft SharePoint
SharePoint finishes last in this ranking but is the most common knowledge store simply by installed base. Document libraries, team sites and permissions come with Microsoft 365, so the license may already be paid, and search reaches files across Teams and OneDrive.
If your compliance team requires everything inside the Microsoft tenant, SharePoint can hold a wiki without a new vendor, new contract or new security review.
Where it falls short
A good knowledge base on SharePoint needs site design, navigation planning and an administrator, and the default result is a pile of folders. Editing pages is clunkier than in dedicated wikis, and authors often fall back to Word files.
The suite price hides what the knowledge use actually costs in admin time.
Wrong for
Wrong for companies without Microsoft 365 skills, and for teams that want a wiki running in a week. A dedicated tool such as Slite, Nuclino or Notion is faster to adopt.
What the data says about this market
Of the eleven products ranked here, one is headquartered in Germany (Nuclino), one in the United Kingdom (Document360, through its parent Kovai.co), one in Australia (Atlassian's Confluence) and eight in the United States. Eight publish plans, an entry price or price bands on their own sites: Notion, Slite, Nuclino, Slab, Tettra, Outline, Confluence and SharePoint inside Microsoft 365. Guru, Bloomfire and Document360 are quote only.
Four products offer a permanent free option: Notion, Nuclino, Slab for up to ten users, and Confluence for up to ten users, while Outline has a free self-hosted Community Edition. Four more offer a trial of 14 to 30 days: Slite, Tettra and Outline in the cloud, plus Nuclino's Starter plan. Three have no free route at all.
The split shows a market where small teams are courted with free plans and larger organizations are handled by sales.
The clearest trend is positioning. Three of the vendors we read, Guru, Bloomfire and Document360, describe AI search, chat or an MCP server as a headline feature, and Guru and Bloomfire lead their homepages with AI governance rather than wiki editing. Buyers should treat that as a reason to ask for a demo of plain page writing, because the daily work is still writing, reviewing and finding pages.
How to choose
1. Decide who owns page quality before you compare tools
The right tool depends on who keeps pages correct, so name that person first. If every team writes its own pages and nobody polices them, a lightweight workspace such as Notion, Slite or Nuclino will see far more use than a governed platform. If a small support or enablement team owns answers and wrong answers cost money, look at Guru or Document360.
If an administrator already runs Microsoft 365 or Atlassian, test SharePoint or Confluence before paying for anything new. Write down the owner, the number of writers and the number of readers.
That page removes half the field and prevents you from buying editor seats for people who only read.
2. Run a two-week pilot with real content
Move twenty real pages into your two or three finalists, not demo content. Choose pages people ask about weekly: leave policy, expense steps, an onboarding checklist. Give five colleagues a task that needs the wiki, such as finding the current travel rule, and time how long it takes.
Check search results for stale versions, try an export, and note whether page owners get any reminder. Free plans and trials from Notion, Slite, Nuclino, Tettra and Outline make this cheap.
For quote-only products, ask the vendor to load a sample of your content into a trial space before you commit.
3. Price a 200-person year and read the exit clause
Ask each finalist for the full annual bill for your headcount, with single sign-on, audit logs and the API switched on, and compare totals, not list prices. Ask how many of your people are editors and how many are readers, since some vendors charge both the same. Request a full export of a test space, then read the contract for a renewal price cap, a data-return clause and the notice period.
Check where content is hosted and whether the vendor lists its sub-processors. A cheap start with a hard exit costs more than a slightly dearer tool you can leave in a week.
Frequently asked questions
What is the best knowledge management software in 2026?
Notion is the best knowledge management software for most companies of 50 to 1,000 people, because it combines a wiki, databases and a free plan at a published price. Slite is second and the better pick when you want a focused knowledge base with AI upkeep checks. Nuclino is third and suits teams that value speed and a European vendor.
Guru is the better choice when verified, role-scoped answers in Slack or Teams matter more than a posted price.
What is knowledge management software?
It is software where employees write, organize and find the company's own know-how. Typical contents are processes, policies, onboarding guides and answers to repeated questions. Core features are an editor, a page structure, search and permissions.
Better products also remind page owners to confirm content, so the wiki does not quietly go out of date. This ranking covers internal use, not customer help centers.
How much does knowledge management software cost?
Published prices here range from free to about $20 per member a month. Slab starts at $6.67 and Tettra at $8, Slite starts at $10 and Pro is $20, Notion's Plus is EUR 9.50, and Outline cloud starts at $10 a month for up to ten members. Guru, Bloomfire and Document360 are quote only.
Single sign-on and audit logs often sit on higher tiers, so price a full 200-person year before deciding.
Is a wiki the same as a knowledge base?
Not quite, though the terms overlap. A wiki is a set of pages anyone on the team can edit, and it grows from the bottom up. A knowledge base usually implies curated, checked answers, often with owners and review dates.
Most products here can be run either way. Notion and Outline lean towards open wikis, while Guru and Tettra lean towards verified answers.
Can we just use SharePoint or Confluence?
Yes, if you already pay for Microsoft 365 or Atlassian and have someone to design the structure. SharePoint comes inside Microsoft 365, and Confluence has a free plan for up to ten users. The cost is admin time and a heavier editing experience.
Companies without that skill set usually get faster adoption from Slite, Nuclino or Notion, which is why the two suites sit lower in this ranking.
Do we need AI features in a knowledge base?
Not to begin with, but AI search that cites its source page is now common and saves time once you have a few hundred pages. Slite, Guru, Tettra and Document360 describe AI answers and several list an MCP connection. The risk is an AI answering from stale pages, so choose a tool that also flags outdated content, and test answers against questions you know.
Which knowledge management software has a free plan?
Notion, Nuclino and Slab have free plans, Slab for up to ten users. Confluence is free for up to ten users with 2 GB of storage. Outline offers a free self-hosted Community Edition with limited features and no support.
Slite, Tettra, Outline cloud and Nuclino's Starter plan offer a trial instead. Guru, Bloomfire, Document360 and SharePoint have no free plan or trial on the pages we read.
How do we stop a wiki from going out of date?
Give every page an owner and a review date, and pick a tool that reminds people. Slite flags outdated pages and drafts updates for the owner, Tettra verifies pages, and Guru checks for conflicting versions and stale content. Without that, set a quarterly review for the twenty most-read pages, archive anything untouched for a year and track search queries that return nothing.
Can I move my existing documents into a new tool?
Usually yes. Tettra imports from Google Docs and Notion, Document360 imports PDF and Word files, and most tools accept Markdown or HTML. The harder part is structure: a pile of files becomes a useful wiki only after someone sorts it.
Plan a clean-up of the most-read pages before import and leave the long tail behind. Test a sample first and check that links and attachments survive.
Which tool suits a company that needs a European vendor?
Among the eleven, Nuclino is headquartered in Germany and Document360's parent says it is headquartered in London. Slite lists EU hosting and an EEA contact address in Paris, though its main mailing address is in San Francisco. Outline can be self-hosted, which lets you keep data in a region you choose.
Ask every vendor where data is stored and which sub-processors it uses.
Why are Confluence and SharePoint not in the top three?
They are majors, and the rule on this site is that dominant incumbents cannot take the first three places. Beyond the rule, both rank on merit in the lower half for this use: they need more setup and upkeep than the lighter tools. They remain sensible when you already live inside Atlassian or Microsoft 365 and have an administrator.
