How we test and compare tools
Hands-on use, 30 days minimum
We compare products after using them in real workflows, importing sample workspaces, and rebuilding common tasks before writing a verdict.
Public pricing, verified monthly
Pricing comes from vendor pricing pages and is rechecked monthly, because comparison content loses trust when plan limits drift.
Conflict of interest, stated up front
AFFiNE competes with many tools here. When a competitor is the better fit for a use case, the page says so plainly.
Frequently asked questions
What is the best note-taking app in 2026?
The best choice depends on the workflow: Notion for team docs and databases, Obsidian for local Markdown PKM, OneNote for free-form capture, GoodNotes for iPad handwriting, and AFFiNE when you need docs plus whiteboards in one local-first workspace.
Notion or Obsidian: which should I pick?
Pick Notion for team collaboration and databases. Pick Obsidian for local files, privacy, and long-term personal knowledge management. Pick AFFiNE if you need collaboration and local-first ownership together.
One workspace across these categories?
AFFiNE combines block-based docs, infinite whiteboards, databases, and local-first storage in one open-source workspace. Use it when your team needs parts of Notion, Obsidian, Miro, and a knowledge base without spreading work across four separate tools.
