Best For
Teams that need a shared wiki, docs and lightweight project tracking with strong collaboration and AI.
Obsidian
Local-first knowledge base and note-taking app that works on a folder of plain Markdown files, extended by thousands of community plugins.
Pros
- Notes are plain Markdown files on your disk, so there is zero lock-in
- Free for personal and commercial use; the commercial licence is optional
- Fast, works fully offline, and no account is needed
- Thousands of community plugins and themes, plus Dataview and native Bases for structured views
- Bidirectional links and graph view excel for personal knowledge management
- Vaults can be versioned with Git and edited by any tool, including AI coding agents
Cons
- No real-time multi-user collaboration; it is designed for individuals
- Official Sync ($4/user/month and up) and Publish ($8/site/month) are paid add-ons
- No built-in AI; AI features depend on community plugins
- Plugin quality varies, and heavy plugin use can complicate setup
- Bases offers structured views but is not a true relational database like Notion's
Best For
Individual developers and researchers who want private, durable Markdown notes they own outright.
Data ownership and lock-in
Obsidian's defining feature is that your vault is just a folder of Markdown files. You can open them in any editor, back them up however you like, put them in Git, and keep reading them if Obsidian disappears. Recent releases even let Obsidian open individual Markdown files outside a vault, reinforcing that it is a viewer for open files rather than a container. Notion stores content as proprietary blocks in its cloud. You can export to Markdown, HTML or PDF, but databases, relations, synced blocks and permissions do not round-trip cleanly. Moving a large workspace out of Notion is a real project. For developers, this cuts both ways. Obsidian's file model plays well with scripts, static site generators and AI coding agents that can read and edit Markdown directly. Notion's model enables rich structure and collaboration that plain files cannot match, and its API and MCP support give programmatic access, but always through Notion's service.
Collaboration and team use
Notion was built for teams. Multiple people edit the same page in real time, comments and mentions drive discussion, and permissions can be set per workspace, teamspace or page. Guests can be invited, pages can be published as sites, and databases turn into shared trackers for roadmaps, bugs or hiring pipelines. Obsidian is fundamentally single-user. Obsidian Sync can share a vault between people, and some teams use Git for shared vaults, but there is no live co-editing, no granular permissions and no commenting system comparable to Notion's. It works for a small group of disciplined collaborators, not for a company wiki. If more than a handful of people need to read and write the same knowledge base, Notion, or another collaborative wiki, is the practical choice. Obsidian shines when one person owns and curates the content. Some teams split the difference: Notion for the shared wiki and project databases, and individual Obsidian vaults for personal notes that later get promoted into Notion when they are ready to share.
AI features and pricing
Notion's AI is now organised around agents. The Business plan at $20 per member per month includes Notion Agent, AI Meeting Notes and enterprise search across connected tools, while Free and Plus only get a trial. Custom Agents that run autonomous workflows are free to try and then cost $10 per 1,000 Notion credits. Plus at $10 per member per month suits teams that want collaboration without the AI bundle. Obsidian has no built-in AI. Community plugins connect vaults to hosted or local models for chat, summarisation and semantic search, which gives flexibility and privacy options but requires setup and your own API keys. Because notes are plain files, external AI tools and coding agents can work on a vault directly. On cost, Obsidian is free for personal and commercial use. Optional Sync starts at $4 per user per month billed annually, Publish is $8 per site per month, and a $50 per user per year commercial licence exists for organisations that want to support development.
Structure, linking and performance
Notion's databases are its strongest structural feature: typed properties, relations, rollups, formulas and multiple views over the same data. For project tracking, content calendars or lightweight CRMs, nothing in Obsidian matches them out of the box. Obsidian has closed some of the gap with Bases, a native feature that turns note properties into table, card and, as of the 1.14 releases, kanban views. The Dataview plugin adds query-driven views for power users. These work well for personal workflows but lack Notion's relational depth and multi-user editing. Where Obsidian clearly wins is linking and speed. Wiki-style links, backlinks, unlinked mentions and the graph view make it excellent for building a connected knowledge base. Because everything is local, search and navigation stay instant even with tens of thousands of notes, whereas large Notion workspaces can feel sluggish, particularly with heavy databases. For very large personal archives, that responsiveness alone is often the reason developers switch.
Verdict
Choose Notion if the notes are a team asset: a company wiki, onboarding docs, specs and lightweight project tracking that many people edit together, especially if you want built-in AI agents and are willing to pay for the Business plan. Choose Obsidian if the notes are yours: a personal knowledge base, engineering journal or research vault where ownership, speed, offline access and plain Markdown matter more than collaboration. Many developers use both, with Notion for shared team spaces and Obsidian for private thinking. If lock-in worries you, Obsidian is the clear winner.
