Book free discovery call →Tana is a powerful outliner-based productivity tool founded in 2020 by Tarjei Vassbotn, Stian Håklev, and Frank Aleksandersen in Oslo. It combines the outliner UX of Roam Research / Workflowy with structured database capabilities through 'supertags' — tags that turn any node into a typed object with custom fields, allowing daily notes, tasks, projects, contacts, and reading lists to interconnect seamlessly. Core features: daily notes flow, supertags with custom fields, voice memo transcription, AI-powered assistance, queries and live views, and cross-platform clients (Mac, Windows, web, iOS). Best for solo founders, knowledge workers, and power users who've outgrown Notion and want structured PKM without the plugin complexity of Obsidian. Free tier supports 4 workspaces and 5K nodes; Pro is $10/month for unlimited, Premium $25/month with AI features. Steep learning curve compared to mainstream notes apps. Direct competitors: Notion (structured + team), Obsidian (local-first markdown + plugins), Roam Research (graph-first, cloud-only, $15/mo), Logseq (open-source local-first outliner), Workflowy (simpler outliner), Mem (AI-first capture). Tana wins on supertags and integrated workflow power; Notion wins on team and ease; Obsidian wins on data ownership.
⏱ 30-second verdict
Tana is a next-generation note-taking and knowledge management tool that treats everything as nodes in a connected graph. It features supertags for creating custom schemas, powerful queries to surface related information, and AI-powered features for automating workflows. Think of it as Notion meets Roam Research with a more structured approach.
🎯 Why it's useful
Founders can build interconnected databases for CRM, meeting notes, product roadmaps, and research that automatically link together—eliminating the need to manually organize or search across multiple docs.
💜 Our take
It's like giving your second brain actual superpowers. The supertag system is genuinely clever, and once you get it, you'll wonder how you ever worked with flat documents.
Daily-note-driven workflow
Capture everything in daily notes — meeting notes, ideas, tasks, contacts. Supertags route information into the right structured views automatically.
Tasks + projects in one place
Tag a line #task with a project reference, and it shows in your tasks view, your project page, and your daily review. No separate task manager needed.
Voice-memo capture
Talk into your phone, Tana transcribes and structures it. The voice-to-structured-data pipeline is excellent.
Founder's second brain
Notes, meetings, contacts, ideas, learnings, all interconnected. The most powerful PKM tool if you'll invest the setup time.
Tana is the productivity tool that the deepest information workers swear by, and that most people bounce off after 10 minutes. It's the most powerful notes + tasks + databases + outliner combo on the market, with a learning curve to match. If you're the kind of person who's spent a decade fighting Notion's structure or building elaborate Obsidian plugin stacks, Tana might be the answer you've been looking for. The core concept: 'supertags' that turn any node in your outline into a typed object with fields. Tag a line as #task and suddenly it has due date, status, and assignee fields automatically. Tag something as #person and it gets contact fields. The same nodes can be referenced anywhere, queried with built-in search, and displayed in different views. It's like Notion's databases but woven directly into the outline rather than separated. For founders who think in outlines and want their daily notes, tasks, contacts, and projects to all flow together, Tana is uniquely powerful. The daily-note-with-everything-flowing-into-it workflow is genuinely transformative once it clicks. Voice memos that auto-transcribe and slot into your knowledge base. AI assistance that's deeply integrated rather than a side panel. The 'capture once, surface everywhere' loop works better than any tool I've tried. The catch: setup time is real. You need to spend a few hours configuring your supertags, building your queries, and learning the keyboard-driven UI. This isn't a 'install and go' product. The activation energy is more like Roam Research or Logseq than Notion — significant for the first week, then disappears once muscle memory sets in. Many founders try Tana, get overwhelmed by the configurability, and bounce back to Notion. That's fine. Tana isn't for everyone. The pricing is steep. Pro at $10/month is reasonable, but the AI features (their newest big feature) live behind the $25/month Premium tier. Compared to free alternatives like Logseq, this is expensive for a single-player tool. My take: try Tana if you've struggled with Notion and Obsidian both — Notion for being too structured and Obsidian for not being structured enough. Tana fills the middle. Block out 4 hours to configure it properly before deciding if it clicks. If it does, you'll never go back. If it doesn't, you'll have wasted an afternoon but learned something about how you actually think about information.

Yes for limited use. Up to 4 workspaces and 5K nodes total on the free tier — enough to try seriously but not enough for long-term use. Pro at $10/month unlocks unlimited nodes. Premium at $25/month adds AI features.
Notion for team collaboration, structured knowledge with explicit databases, and a gentler learning curve. Tana for solo deep workers who want supertags weaving structured data into their daily outline. Notion is the safer team default; Tana is for the power-user solo founder who's outgrown Notion.
Tana has more powerful built-in features (supertags, queries, daily notes flow). Obsidian is more extensible via plugins. Obsidian wins on local-first data ownership; Tana wins on integrated workflow. If you like configuring tools, Obsidian. If you want power without the plugin maze, Tana.
Tags that turn nodes into typed objects with custom fields. Tag a line #task and it gets due date, status, assignee fields automatically. Tag it #book and it gets author, rating, status fields. Same nodes can be queried, referenced, and displayed in different views. The killer Tana feature.
Limited team support. Workspace sharing exists in Pro+ but Tana is primarily designed for solo power users. For team knowledge work, Notion or Slite is a better fit. Tana shines for individual deep thinkers and founders running everything from their own brain.
