Editorial verdict
Choose Notion if: You want docs, wikis, databases and project pages together in one cloud workspace where a team can edit in real time, with built-in AI (per notion.com).
Choose Obsidian if: You want private, local Markdown files you fully own, offline access, and a plugin ecosystem — and don't mind paying for sync and publishing (per obsidian.md).
Overall: Notion is a cloud workspace with real-time collaboration and AI; Obsidian is a local-first app where your notes are plain-text files on your disk. Notion's free tier carries file-size and history caps; Obsidian's app is free but Sync ($4/user/mo) and Publish ($8/site/mo) are paid add-ons.
This verdict is independent of any affiliate or commercial relationship with either product.
What they are
Notion (notion.com) is an all-in-one workspace combining docs, wikis, databases and project views with collaboration and built-in AI. Obsidian (obsidian.md) is a local-first knowledge base that stores notes as plain-text Markdown files on your device.
Pricing (official pages, checked September 2026)
- Notion: the app is free with unlimited pages/blocks for individuals; Plus $9.50 and Business $19.50 per member/month billed yearly; Enterprise is custom (notion.com/pricing).
- Obsidian: the app is free for personal and commercial use; Sync $4/user/month and Publish $8/site/month billed annually; Catalyst $25 one-time (obsidian.md/pricing).
Where they differ
- Notion runs in the cloud and is designed for shared workspaces; free-tier uploads cap at 5MB per file and page history at 7 days.
- Obsidian keeps everything local and offline by default, with no data stored on Obsidian's servers unless you use Sync or Publish.
- Notion's databases (subtasks, dependencies, custom properties) are structured; Obsidian links notes in a graph and supports thousands of community plugins.
- Notion AI (chat, autofill, Agents) is built in; Obsidian's AI features come from community plugins rather than a first-party assistant (as of its pricing FAQ).
Bottom line
Pick Notion for a shared, structured workspace in the browser. Pick Obsidian if ownership, plain-text notes and offline-first behavior matter most — and treat Sync/Publish as optional paid add-ons.
