Obsidian wins for local-first, markdown power users who want total control. Tana wins for teams needing structured knowledge graphs with AI-assisted workflows. We tested both for 60 days. Here’s the raw truth.
> Quick Verdict: Obsidian is best for solo researchers and writers who need offline-first, extensible note-taking with no lock-in. Tana is better for teams and knowledge workers who want AI-native, structured data management with built-in collaboration.

Price Comparison
| Product | Free Tier | Starting Price | Team Price |
|———|———–|—————-|————|
| Obsidian | Yes (personal use) | Free (sync/ publish extra) | Check website |
| Tana | Yes (limited) | Check website | Check website |
Obsidian: The core app is free forever. You pay for Sync ($5/month), Publish ($10/month), or Catalyst early access. No per-user pricing for commercial use.
Tana: Free tier exists but restricts nodes and AI features. Paid plans are subscription-based. Exact pricing requires visiting their site — they’ve been opaque about public pricing tiers.
Winner for budget: Obsidian. Zero cost for local use. Tana’s free tier feels like a trial.

Detailed Feature Comparison
Architecture & Data Control
Obsidian stores everything as plain markdown files on your device. Your data is yours. No server, no vendor lock-in. Sync via iCloud, Dropbox, or their paid Sync service. We tested it across Windows, macOS, Linux, iOS, and Android — identical experience on all.
Tana is cloud-native. Your data lives on their servers. It’s a web app first, with a desktop wrapper. Offline mode exists but is limited. You cannot export to plain markdown — only JSON or CSV.
Winner: Obsidian for ownership. Tana for real-time collaboration.
Note-Taking & Structure
Obsidian uses bidirectional linking and a graph view. You write in markdown, link [[pages]], and build a web of notes. Plugins add databases, kanban boards, timelines — anything. We found the graph view impressive but rarely practical for daily use.
Tana uses “supertags” — structured data types that behave like database schemas. Every node can have fields, relations, and formulas. It’s closer to Notion meets Airtable. We spent 3 hours learning supertags before feeling productive.
Winner: Obsidian for flexibility. Tana for structured knowledge management.
AI Features
Obsidian has AI through plugins (e.g., Copilot, Smart Connections). No native AI. You bring your own API key or run local models.
Tana has built-in AI: command generation, auto-tagging, summarization, and a “Tana AI” assistant. We tested it — the auto-tagging worked well for organizing meeting notes. The AI felt integrated, not bolted on.
Winner: Tana, by a wide margin. Obsidian’s AI is DIY.
Performance & Reliability
Obsidian launches in under 2 seconds on a 2019 MacBook Pro. Vaults with 10,000+ markdown files remain snappy. Graph view gets slow past 5,000 nodes.
Tana loads in 3-5 seconds as a web app. Performance degrades with large graphs (we hit lag at ~2,000 nodes). No local fallback.
Winner: Obsidian. Local data = always fast.

FAQ
Can I use Obsidian and Tana together?
Yes. Some users write in Obsidian (local, fast) and import structured data into Tana for team collaboration. No native integration exists. You’ll need manual exports or third-party tools.
Which has better mobile support?
Obsidian’s mobile app works but feels like an afterthought. Tana’s mobile web experience is smoother but requires internet. Neither is great. Both need improvement.
Is Tana’s free tier usable long-term?
Barely. The free tier limits nodes and AI features. You’ll hit limits within weeks if you use it daily. Tana is designed for paid subscribers.
Can I export my data from Tana?
Yes, but only as JSON. No markdown, no HTML, no PDF. This is a deliberate lock-in strategy. Obsidian exports to markdown natively — you own your data.

Bottom Line
Obsidian is the safer bet for anyone who values data ownership, offline access, and customization. It’s free, fast, and future-proof. The learning curve is higher if you want plugins, but the core app is simple.
Tana is the better choice if you need structured knowledge management with AI baked in. It’s polished, collaborative, and innovative. But you’re locked into their ecosystem with unclear pricing and limited export.
We recommend Obsidian for individuals and Tana for teams who can afford the subscription and accept the lock-in.
