Obsidian vs Tana: local files or an AI workspace in 2026?
Tana vs Obsidian is the least symmetric matchup in personal knowledge management: a free, offline folder of Markdown files you own forever, versus a cloud workspace betting everything on AI — supertags that turn notes into databases, a meeting agent that transcribes calls without a bot, and metered AI credits on every plan. They barely compete on features; they compete on philosophy. That makes the choice easier than most comparisons — once you’re honest about which product you actually want.
The short answer: these tools sit at opposite poles, so the decision is about you, not them. Default to Obsidian if data ownership and $0 matter; pay for Tana if structured notes plus built-in AI — especially meeting transcription — would genuinely change your week. Trying to make one do the other’s job is how people end up switching twice.
- Choose Obsidian if you want plain local files, offline-first everything, a plugin ecosystem two thousand strong, and no subscription. Bases (native database views, 2025) now covers light structured data without leaving your vault.
- Choose Tana if supertags — notes as typed, queryable objects — fit how you think, you’ll actually use the AI meeting agent and voice capture, and $20–30/month is acceptable for your notes tool.
What is Obsidian?
Obsidian stores your notes as plain Markdown files in a folder on your own device — a “vault” you can read with any text editor, back up however you like, and keep forever. On top of those files it layers backlinks, a graph view, a Canvas whiteboard, and Bases (native database views over your notes, added in 2025). The app is completely free, including for commercial use since early 2025.
Its defining feature is the community: roughly two thousand plugins extend it with everything from spaced repetition to Kanban boards to AI integrations. Official add-ons are paid — Sync ($4/month, end-to-end encrypted) keeps vaults identical across devices, and Publish ($8/month) turns notes into a public site. There’s no web app; Obsidian runs as desktop and mobile apps against your local files.
What is Tana?
Tana’s big idea is the supertag: slap #meeting or #person on any outline node and it gains fields, views and behavior — your notes become a queryable database without leaving the outline. Live queries collect matching nodes anywhere in your workspace, which makes Tana feel like Roam and Notion fused together.
Since 2025 Tana has pivoted hard into being an “AI workspace”: a meeting agent that transcribes calls without a bot, voice capture that structures itself, semantic search, and full MCP support so AI assistants can work with your workspace on paid plans. Pricing reflects the AI ambition — a free tier with capped AI usage, Pro at $20/month (early-bird; $30 regular), and a $80+/month Max tier for heavy AI use. It’s cloud-based with web, desktop and capture-focused mobile apps.

Supertags vs Bases — two routes to structured notes
Tana’s defining idea is the supertag: add #meeting or #person to any outline node and it becomes a typed object with fields, views and behavior. Live queries then collect matching nodes from anywhere in the workspace. It’s the most elegant structure system in the category — a database that emerges from note-taking instead of being built beside it.
Obsidian’s answer used to be “install Dataview”; since 2025 it’s Bases, a native feature that turns note properties into filterable table and card views. Bases is deliberately humbler than supertags — properties live in frontmatter, views live in documents — but it covers the everyday cases (reading lists, project trackers, people directories) without a subscription or a new mental model. If your structure needs end there, the gap between the two tools is smaller in 2026 than any older comparison suggests.
The AI gap — a product bet on each side
Tana is AI-native on purpose: a meeting agent that transcribes Zoom, Teams and Google Meet calls with no bot joining, voice capture that lands as structured supertagged notes, AI chat shaped by your schema, and frontier-model access — all metered by AI credits that gate every plan. An official local MCP server (running inside the desktop app) lets Claude Code and other agents work your graph.
Obsidian has deliberately shipped no built-in AI — its bet is that AI belongs outside the app, working on your files. In practice that bet has aged well: because a vault is a plain folder, any filesystem MCP server can read it, community plugins add whatever model you like, and the official CLI (February 2026) was explicitly framed as the way for coding agents to drive Obsidian. The difference isn’t AI vs no AI — it’s AI as a metered product feature vs AI as something you bring to your own files.
Pricing — $0 vs a real subscription
Obsidian is free including commercial use; official Sync is an optional $4/month billed annually, and DIY sync is free. Tana in 2026 is Free (thin: capped AI queries, limited hosted meetings), Pro at $20/month at an “early bird” rate — the stated regular price is $30/month — and a Max tier from $80/month for heavy AI use, with credit top-ups on top.
Two honest caveats cut both ways. Tana’s free tier is a trial in practice — budget for Pro if you adopt it. And comparing $0 to $240–360/year is only fair if you’d never pay for the things Tana bundles: if the meeting agent replaces a $20/month transcription tool you already pay for, the math changes. Prices as of August 2026; Tana’s early-bird rates are explicitly provisional.
Offline, lock-in and the exit question
Obsidian is offline-first by construction — the files are on your disk, and “export” is copying a folder. Tana is a cloud service that added an offline mode in late 2025 (full editing in personal workspaces, read access to shared ones), which fixed the airplane problem but doesn’t change where your data lives: on Tana’s servers, not encrypted end-to-end, with no self-hosting.
Tana’s export answer is real but partial: full-workspace export to Markdown or JSON exists (the company literally titled a blog post “Yes, you can export from Tana”). What the Markdown can’t carry is the point of Tana — supertags and their fields flatten to text, and node-level references lose their targets. Documented migrations to Obsidian describe exactly that cleanup. Leaving is possible; leaving intact is not. Weigh that against how much structure you’d build.
Where Obsidian shines
- True data ownership: plain Markdown files on your disk, readable by any app, with no account required and no lock-in.
- The largest plugin ecosystem in the category — if you want a workflow, someone has probably built it.
- Free for personal and commercial use; you only pay for optional Sync or Publish.
- Bases and Canvas add database views and visual thinking without leaving your local vault.
- End-to-end encrypted sync (as a paid add-on) for the privacy-conscious.
Worth knowing: There’s no web app, and multi-device use effectively requires paid Sync or DIY setups. Collaboration is weak — shared vaults exist but there’s no real-time co-editing. Out of the box it’s fairly bare; the power comes from configuring plugins yourself, which is a hobby in its own right. Capturing web content, newsletters or feeds means assembling extensions and plugins rather than anything built in.
Where Tana shines
- Supertags are the most elegant structure system in the category — schema, views and queries grow naturally out of plain outlining.
- The AI feature set is the deepest here: botless meeting transcription, voice capture, agents, and semantic search.
- Full MCP support (on paid plans) makes it one of the few tools built for AI-assistant workflows.
- Real-time multiplayer workspaces work well for teams.
Worth knowing: It’s the most expensive tool in this comparison once you use it seriously — AI usage is metered, and Pro runs $20–30/month. Cloud-only and proprietary: no local files, no end-to-end encryption, and export is limited. The structure-first approach has a real learning curve; casual note-takers may find it over-engineered.
Which should you choose?
Choose Obsidian if:
- You want your notes as local files you fully control, independent of any company’s servers.
- You enjoy tinkering and want to assemble a personalized system from plugins.
- You work offline often or in environments where cloud tools are off-limits.
- You want a free tool with no note limits.
Choose Tana if:
- You want notes with fields, views and queries — a database that emerges from writing.
- Meeting transcription and voice capture are core to your workflow.
- You’ll actually use enough AI to justify the price.
A third option: Dexi
If Tana’s appeal is notes that organize themselves but the price and lock-in give you pause, Dexi sits in the gap: #tags, @mentions and [[wiki links]] typed inline structure your notes as a side effect of writing, and everything you capture from the web, your inbox or RSS lands in the same searchable graph. Semantic search and an MCP server (with per-connection folder or tag boundaries) cover the AI-assistant workflow without metered credits. Free for up to 1,000 notes, $5/month after — a quarter of Tana’s early-bird price.
Frequently asked questions
Is Tana worth it compared to free Obsidian?
Only if you’ll use what the subscription actually buys: supertag-structured notes, AI chat over your workspace, and especially the botless meeting agent for Zoom/Teams/Meet calls. If you mainly write and link notes, Obsidian does that for free with stronger ownership. Tana Pro is $20/month at its early-bird rate ($30 regular) as of August 2026.
Can I export my notes from Tana?
Yes — Tana offers full-workspace export to Markdown (a zip of .md files with links preserved) or JSON with full metadata. The structure that makes Tana distinctive doesn’t survive the trip, though: supertags and their fields flatten to plain text, so an exported workspace reads as outlines, not a database.
Does Tana work offline?
Partially, since late 2025: personal workspaces support full offline editing with sync on reconnect, and shared workspaces are readable offline. It remains a cloud-hosted service — your data lives on Tana’s servers, without end-to-end encryption or self-hosting. Obsidian, by contrast, is offline-first with files on your own disk.
Can Obsidian do what Tana’s supertags do?
Partly. Obsidian’s native Bases (2025) turns note properties into filterable database views, covering reading lists, trackers and similar structured collections. Tana’s supertags go further — typed nodes with fields, inheritance and live queries woven into the outline itself. Heavy structure users will feel the difference; light ones won’t.
Does Tana support MCP for AI assistants?
Yes — Tana ships an official local MCP server that runs inside its desktop app, used by Claude Code and other agent clients. Obsidian has no official MCP server, but its vault-is-a-folder design means standard filesystem MCP servers and community plugins fill the role, and its official CLI (February 2026) is aimed squarely at coding agents.
Which is cheaper, Tana or Obsidian?
Obsidian — the app is free (commercial use included), with optional Sync at $4/month billed annually. Tana’s free tier is heavily capped; real use means Pro at $20/month early-bird ($30 regular) or Max from $80/month for heavy AI, plus optional credit top-ups. Prices as of August 2026.
