Comparison: knowledge management software

6 Knowledge Management Tools Compared: Which System Fits Your Team

Short answer: Confluence fits if you already use Jira or other Atlassian products. Notion and Nuclino fit if your wiki, notes and project lists should live in one place, Nuclino at a lower price. Slite and Guru focus on AI search and verified answers, Slite with data hosted in the EU, Guru for larger companies on request. BookStack is free and runs on your own server. None of these systems fills itself: what a person who is about to leave knows has to be drawn out of them first.

How we chose these tools

This list is not a ranking and not a long-term test. It shows six widely used tools with different approaches, so you can quickly see which two or three deserve a closer look.

  • Real knowledge management

    Only wikis and knowledge bases for internal knowledge, no project management or help desk software with a wiki on the side.

  • Verifiable prices

    We read prices, plans and features on each vendor's pricing page on the date shown. Where a vendor publishes no price, we say so.

  • Data protection

    Data location, single sign-on and how the AI treats your data, as far as the vendor states them. For teams in the EU this is often the deciding factor.

  • Different approaches

    One market leader, two tools for wiki and notes, two built around AI search and one free option you host yourself.

The tools one by one

Confluence: the wiki for Atlassian teams

Confluence by Atlassian organises knowledge in spaces and page trees, with databases, whiteboards and a large template library. Atlassian bundles Confluence with Jira, Loom and its AI, Rovo.

Strengths

  • Free plan for up to 10 users
  • Fine-grained space and page permissions, page versions
  • On paid plans you can pin your data to the EU or Germany
  • Also available as a self-managed Data Center edition

Limits

  • Single sign-on on Standard and Premium needs an extra subscription (Atlassian Guard)
  • Enterprise only with annual billing and pricing on request
  • The free plan has 2 GB of storage and community support only
Pricing
Free for up to 10 users. With monthly billing the price calculator shows $7.15 (Standard) and $14.10 (Premium) per user and month for a small team, less for many users; annual billing saves up to 17% according to Atlassian.
A good fit if
Your team already works in Jira, you need many spaces with their own permissions, or hosting in Germany is a must.

Notion: wiki, notes and databases in one

Strengths

  • Very flexible: wiki, task lists and databases in the same tool
  • Free plan to get started
  • Business adds an AI agent, AI meeting notes, enterprise search and SAML SSO
  • According to Notion, Notion AI does not use your data for training unless you opt in

Limits

  • Data is stored in the US by default; EU data residency is only available on Enterprise
  • On the Plus plan Notion AI is a trial only
  • The freedom needs rules, otherwise the workspace grows hard to navigate
Pricing
Free at €0. Plus €9.50 and Business €19.50 per seat and month billed annually, €11.50 and €23.50 billed monthly (prices shown for the EU). Enterprise on request.
A good fit if
You want wiki, notes and project data in one tool and can accept US hosting or book Enterprise.

Nuclino: the lean team wiki

Nuclino is a wiki for teams who write documents together in real time. Items can be shown as a list, a board, a table or a graph of how they link to each other.

Strengths

  • Low entry prices and a 14-day trial without a credit card
  • List, board, table and graph views
  • Integrations such as Slack and Google Drive, plus an API
  • Workspaces can be published as a website

Pricing
Free at €0. Starter €6 and Business €10 per user and month billed annually, €8 and €12 billed monthly (prices shown for the EU).
A good fit if
A small team wants a clear wiki at a low price and does not need project management in the same tool.

Slite: knowledge base with AI answers and EU hosting

Slite is a knowledge base that answers questions from your documents with AI. Documents can be verified, so it stays visible what is still correct.

Strengths

  • AI search and answers on the smallest plan
  • Document verification and a panel to clean up outdated content
  • According to Slite, all production data is hosted in the EU (Belgium, Google Cloud)
  • Export to PDF, Markdown and HTML

  • The agent and search across connected tools only on Pro
  • Agent requests use credits, and extra credits cost more

A good fit if
Your team should get answers quickly through AI and hosting in the EU matters to you.

Pricing
Guru publishes no prices. According to Guru, the package is tailored to your scale, knowledge complexity and AI maturity and agreed with the sales team.
A good fit if
A larger company wants to bring knowledge from many systems together with permissions, governance and AI answers.

BookStack: free wiki to host yourself

BookStack is a free wiki under the MIT licence that you install yourself. Content sits in books, chapters and pages, written in a WYSIWYG or Markdown editor.

Where SkillPass fits in

SkillPass is not a knowledge management system and not a wiki, and it does not replace any of the tools above. It solves the problem that comes first: when someone leaves, most of what they know is in no system at all. You send one link, the person has one conversation with an AI interviewer, by voice or text, usually 60 to 90 minutes. The result is a handover handbook as a PDF, as Markdown or as an AI skill, and you can move its content into your wiki afterwards. Price: $39 per handover plus VAT, no subscription.

What SkillPass does not do

SkillPass does not keep knowledge available for the whole team over time, has no search across your documents and no permission management. It has no access to e-mails, files or screens and only knows what is said in the conversation. By default the handover is deleted 30 days after completion. There is no free trial; the sample handbook shows the result.

Questions about knowledge management tools

What is a knowledge management tool?

A knowledge management tool is software where a team records, organises and finds its knowledge: usually a wiki or knowledge base with search, permissions and versions. Newer tools also answer questions with AI from the stored documents.

Which knowledge management tools are free?

Confluence is free for up to 10 users, Notion has a Free plan, Nuclino is free up to 50 items, and BookStack is open source and completely free but needs your own server. Slite only offers a 14-day trial and Guru has no public plan (as of November 2026).

How much do knowledge management tools cost?

Entry-level paid plans cost about 6 to 10 dollars or euros per user and month: Nuclino €6, Confluence $7.15 (monthly, small team), Notion €9.50 and Slite $10, billed annually unless noted. Plans with AI and single sign-on usually cost 10 to 20 per user. Guru only quotes on request.

Which knowledge management tools host data in the EU?

Slite says all production data is hosted in the EU (Belgium). Confluence lets you choose the EU or Germany as data location on paid plans, Notion only on Enterprise. BookStack runs on your own server. Nuclino's and Guru's security pages do not name a data location, so ask them directly.

Is SkillPass a knowledge management tool?

No. SkillPass is an emergency handover tool: the departing person has one conversation with an AI interviewer, and the result is a handover handbook. It does not keep knowledge for the team over time. You can move the handbook as a PDF or Markdown into any of the tools above.

Is this comparison up to date?

Yes, as of November 2026. We checked prices and features on the vendors' official websites and check them again at least every three months. Prices can differ by country, currency and team size; the vendor's pricing page is what counts.
