Notion vs Confluence vs KnowVault: which knowledge management tool should you choose?

Choosing a knowledge management tool in 2026 means navigating dozens of solutions that all claim to do the same thing. Notion, Confluence, GitBook, Slab, Outline, Document360, Bloomfire, Guru… The list is long, and the comparisons you find online are often biased (written by the vendors themselves).

This comparison is written by the KnowVault team, so it's clearly not neutral. But it is honest: we explain when Notion or Confluence is the best choice, and we spell out KnowVault's limits. The goal isn't to win by default, it's to keep you from picking the wrong tool.

How we compared

Three tools, because they represent the three main approaches to knowledge management in 2026:

• Notion: the flexible workspace approach (text, tables, databases)
• Confluence: the traditional company wiki approach (document collaboration)
• KnowVault: the video-first approach (capturing expertise by recording it)

For each one, we look at 7 criteria: adoption, content format, search, collaboration, price, GDPR compliance, and ideal use case.

Notion: the flexible Swiss Army knife

Strengths

Notion has become the go-to tool for startups and product teams. Its main strength is flexibility. You start with a blank page and build whatever you want: a wiki, a CRM, a roadmap, a knowledge base, internal documentation.

Its relational databases are remarkable. You can link a "Customer" page to a "Contract" page and a "Support ticket" page without any external plugin. It's powerful for people who know how to use it.

The interface is modern and pleasant to use, which helps adoption, at least at first.

Weaknesses

The flip side of flexibility is organizational entropy. Beyond 50 people, Notion workspaces quickly become chaotic. Everyone creates pages following their own logic, internal links break, and search becomes ineffective.

Search, in fact, remains a weak point. It has improved, but it doesn't match a dedicated tool like Confluence or Algolia.

Notion handles video content poorly. You can embed a YouTube or Loom video, but you get no native encoding, no secure private storage, and no search inside transcripts.

Finally, Notion's main servers are in the United States. For sensitive data, that's not a minor detail (transfers outside the EU, exposure to the CLOUD Act).

Pricing

• Free: limited to 1,000 blocks (only enough for personal use)
• Plus: $10/user/month
• Business: $18/user/month
• Enterprise: on quote

Note: pricing is per user, not per contributor. Someone who rarely reads anything is billed like a daily editor.

When Notion is the right choice

• Product or engineering team (fewer than 50 people)
• Need for maximum flexibility
• Mixed use cases (docs, projects, lightweight CRM…)
• GDPR compliance isn't critical

Confluence: the enterprise standard

Strengths

Confluence is the default tool in large companies. Its strength is maturity: twenty years on the market, deep Jira integration, granular permissions, approval workflows, SSO/SAML, audits.

For an organization with governance requirements (controlled publishing, archives, traceability), Confluence has no rival.

Its plugin ecosystem (the Atlassian Marketplace) lets you extend the tool in every direction imaginable: Lucidchart diagrams, glossaries, customer knowledge bases, and more.

Weaknesses

The UX is… let's say "functional". Next to Notion, the interface shows its age. The editor is less pleasant and creating content takes more effort.

Adoption is Confluence's Achilles' heel. Many companies have an official Confluence… and an unofficial Notion where teams actually document things. If your people don't enjoy writing in it, your pages stay empty.

Like Notion, Confluence is poor at video content. It's a text tool, designed around pages.

Pricing becomes prohibitive beyond 100 employees.

Pricing

• Free: up to 10 users
• Standard: $6.40/user/month (up to 50,000 users)
• Premium: $12.30/user/month
• Enterprise: on quote

On the plus side: Atlassian offers European data centers as an option for compliance.

When Confluence is the right choice

• Company with more than 100 people and strong governance
• Already using Jira / Atlassian
• Need for SSO, an audit trail and granular permissions
• Product or customer documentation that can be made public

KnowVault: capturing expertise on video

Strengths

KnowVault comes at the problem from a different angle. The conviction behind it: a company's critical knowledge isn't in pages, it's in its experts' heads. And writing in a wiki takes so much effort that this knowledge never makes it there.

KnowVault lets an expert record a short video (2 to 10 minutes) by sharing their screen and explaining out loud. The video is then organized, tagged and searchable. It's a knowledge base, but with a way of capturing knowledge that costs far less than writing.

The main strengths:

• Fast capture: 5 minutes of video recorded in 5 minutes, vs. 2 hours to write the equivalent
• Capturing hands-on knowledge: showing a software workflow is trivial on video and tedious in text
• 100% EU hosting (servers in France, data in Ireland), GDPR compliance built in
• AES-256 encryption of videos at rest and in transit
• Pricing model: only contributors pay. Viewers are free and unlimited.

Weaknesses

KnowVault is not a general-purpose wiki. If you need to write 200 pages of product documentation with tables and relational databases, it's not the right tool.

Video also has its limits: it's harder to skim than text. For a quick reference ("what's our head office's postcode?"), a Notion page is more efficient.

Finally, KnowVault is a young tool. Its ecosystem isn't as mature as Confluence's.

Pricing

• Starter: free for up to 3 contributors, unlimited viewers, 5 GB of storage
• Pro: €13.90/contributor/month, unlimited free viewers, 1 TB shared
• Enterprise: on quote (dedicated server, SSO, SLA)

It's the only one of the three tools where the people consuming content aren't billed. For a team with 10 experts producing content and 200 people watching it, the price gap is massive.

When KnowVault is the right choice

• Teams with complex or hands-on business knowledge (business software, operational processes, internal training)
• Recurring onboarding (you hire regularly)
• Critical risk of "knowledge loss" (departures, retirements, turnover)
• Strong requirements for GDPR compliance and EU hosting
• Many viewers for few producers

Comparison table

How to choose: a decision matrix

Choose Notion if: you're a startup with fewer than 50 people, you need a versatile tool, you work mostly in project mode, and GDPR compliance isn't a priority.

Choose Confluence if: you're a mature company, you already use Jira, you have strong governance requirements, and text covers 95% of your needs.

Choose KnowVault if: your critical knowledge relies on experts who don't write, you hire regularly, half of your processes are hands-on (using software, demos, customer journeys), and GDPR compliance is non-negotiable.

Combine several tools if your use cases justify it. Many teams use Confluence for "official" product docs and KnowVault to capture operational expertise. Notion can be added for project management. It's a stack that works, as long as the boundaries between tools are clear to your teams.

The criterion people often forget: capture friction

Beyond features, the real success factor of a knowledge management tool is capture friction. How much effort does an expert have to put in to pass on what they know?

• Open Notion, structure a page, write 800 words: 1 to 2 hours
• Open Confluence, pick the space, follow the template, write: 1 to 2 hours
• Open KnowVault, start recording, show while talking: 5 to 10 minutes

This friction explains why 80% of company wikis are dead or out of date. The marginal cost of a wiki page is too high to pay off.

It's also why we built KnowVault: to reduce friction to the point where capturing knowledge becomes faster than the verbal explanation it replaces.

Want to try it?

The easiest way to evaluate KnowVault is the public demo: no sign-up, no credit card. You can freely explore a pre-filled workspace.

For Notion and Confluence, their free plans are also enough to evaluate them.
