Obsidian perfected the personal Markdown vault.

Own your files and collaborate
The reason people love Obsidian is that notes are plain Markdown files on disk, usable in any editor and versionable with git. Strata keeps that property while making the documents multiplayer. The strata link CLI live-syncs a Space to an ordinary folder: edit locally in your favorite tools and changes merge into the shared document in real time, while teammates and agents edit the same document from the web. No proprietary format, no export step.
Comments, suggestions, and review built in
Obsidian is single-player by design. Collaboration means bolting on third-party plugins for shared editing, and there is no native commenting or review surface. Strata ships anchored comment threads, tracked suggestions with accept and reject, presence, and complete version history on every plan, so a team can draft, review, and publish without leaving the document.
AI agents on the team
Obsidian's AI story lives in community plugins, and its local-model support through Ollama is genuinely good for personal use. Strata treats AI as a team member: a native MCP server lets Claude, ChatGPT, Cursor, and any MCP client search your knowledge base with hybrid semantic retrieval, edit documents, leave comments, and file suggestions for review, governed by the same permissions as people. Scheduled document-first agents keep recurring work moving without a human kicking it off.
When Obsidian is the right choice
If you want a personal, fully offline vault with end-to-end encrypted sync, thousands of plugins, and zero dependence on a vendor, Obsidian is excellent and its core app is free. Strata is the better fit the moment more than one person, or one agent, needs to work in the same documents: collaboration, review, publishing, and governance are built in rather than assembled from plugins.
Frequently asked questions
- Is Strata an Obsidian alternative for teams?
- Yes. Strata offers the same plain-Markdown ownership philosophy with built-in real-time collaboration, comments, tracked suggestions, publishing, and team permissions, which Obsidian only approximates through third-party plugins.
- Can I keep my Markdown files on disk with Strata?
- Yes. The strata link CLI live-syncs a Space to a local folder of ordinary Markdown files, two-way. Local edits merge into the shared CRDT document in real time, and web or agent edits write back to your disk.
- Does Obsidian support real-time collaboration?
- Not natively. Real-time editing in Obsidian requires third-party community plugins such as Relay or Peerdraft, and there is no built-in commenting, review, or permission model.
- Can I import my Obsidian vault into Strata?
- Yes. Obsidian vaults are plain Markdown, which Strata imports natively. Upload files directly or link a folder with the strata link CLI to bring a vault into a shared Space.
- How does Strata pricing compare to Obsidian?
- Obsidian's app is free, with Sync from $4 per user per month and Publish at $8 per site per month as add-ons. Strata has a free plan for up to 5 members, and Pro at $12 per seat per month (or $10 annual) includes sync, publishing, AI credits, and audit logs in one plan.
