Notion AI vs Confluence AI vs Slite: Knowledge Management with AI

Finding information in company wikis has always been painful. AI-powered knowledge management promises to fix this - surfacing relevant docs instantly, generating summaries, and even creating content. We tested Notion AI, Confluence AI (Atlassian Intelligence), and Slite to see which delivers.

Quick verdict

Our recommendation: Use Notion AI for most teams - the combination of flexible workspace design and capable AI features makes it the best general-purpose option. Choose Confluence if you're committed to the Atlassian ecosystem and need deep Jira integration. Consider Slite if you want focused simplicity without feature bloat.

What we tested

We evaluated each platform across:

1. AI search: Finding answers across documentation
2. Content generation: Creating docs, summaries, action items
3. Q&A accuracy: Answering questions about existing content
4. Integration: Connection with other tools
5. User experience: Daily usability for teams

Testing conducted with 500+ page knowledge bases on each platform.

2. Create Jira incident ticket (auto-creates from Slack /incident)
3. Assign incident commander per on-call rotation
4. Follow runbook for specific system affected
5. Post-mortem required within 5 days for P1/P2

Use case recommendations

Startup (10-50 people)

Winner: Notion AI

Flexibility to use for docs, projects, and databases. AI assists across all content types. Scales with team growth.

Enterprise Atlassian shop

Winner: Confluence AI

Deep Jira integration is essential if your engineering runs on Atlassian. Cross-product AI search adds significant value.

Small team prioritising simplicity

Winner: Slite

Lower cost, easier onboarding, sufficient AI for basic needs. Get started in hours, not days.

Content-heavy marketing team

Winner: Notion AI

Best content generation and editing assistance. Database features for content calendars and asset management.

Engineering documentation

Winner: Confluence AI or Notion AI

Both handle technical docs well. Choose based on existing tooling - Atlassian shops go Confluence, others Notion.

Distributed async team

Winner: Slite

Focus on findability over features. Fast search and clean interface support async workflows.

Migration considerations

To Notion from Confluence

1. Export Confluence spaces as HTML/PDF
2. Use Notion importer (supports Confluence)
3. Reorganise structure (Confluence spaces → Notion databases/pages)
4. Rebuild key integrations
5. Train team on new workflows

Allow 2-4 weeks for teams of 50+. Notion's importer handles basic structure but custom macros need manual recreation.

To Slite from Notion

1. Export Notion workspace
2. Import to Slite (Markdown support)
3. Simplify structure (Slite is flatter)
4. Set up team permissions

Simpler migration but you'll lose database functionality.

AI accuracy analysis

We tested 100 questions across each platform:

Analysis: Notion AI edges out on most categories. Confluence AI excels at cross-referencing (thanks to Jira integration). Slite is sufficient for straightforward lookups but struggles with complex queries.

All platforms occasionally hallucinate - always verify critical information.

Our verdict

Notion AI offers the best combination of platform flexibility and AI capability. The workspace model adapts to diverse team needs, and AI features are integrated thoughtfully throughout. The add-on pricing is annoying but the value justifies it for most teams.

Confluence AI makes sense if you're already invested in Atlassian. The Jira integration is genuinely valuable for engineering teams. But the dated UX and complexity tax is real - don't choose Confluence just for AI if you're not already committed to the ecosystem.

Slite is underrated for teams that just need a wiki that works. The simplicity is a feature, not a limitation. AI search is good enough for most queries. If you don't need Notion's flexibility or Confluence's integrations, Slite gets the job done at lower cost.

For most teams evaluating these platforms fresh, start with Notion AI. Move to Confluence only if Atlassian integration is essential.
