Tana vs Capacities

Tana is an AI-native outliner where “supertags” turn notes into structured, queryable objects; Capacities is an object-based notes studio where every note is a typed thing — a person, a book, a meeting. Here’s how they compare on pricing, platforms, linking, search, capture and collaboration — and how to decide between them.

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.

What is Capacities?

Capacities organizes your knowledge by what things are. Instead of files in folders, you create objects — people, books, meetings, projects, quotes — each with its own properties and views, connected through backlinks and daily notes. Browsing by object type (every book you’ve noted, every person you’ve met) falls out of the design for free, and a calendar-centric daily view ties it to your day.

It’s a polished, cloud-based app on web, desktop and mobile, with a generous free core plan; Pro (about $10/month billed annually) adds the AI assistant, calendar sync and advanced queries. In July 2026 it shipped a developer API with OAuth, opening it up to integrations. One deliberate omission to know about: there is no collaboration, and the team has said it isn’t planned — Capacities is intentionally a personal tool.

Tana vs Capacities at a glance

Pricing and features as of mid-2026 — check each product’s site for current details.

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.

Where Capacities shines

• Object types with properties give structure without the rigidity of databases or the chaos of free-form notes.
• One of the most polished, beautiful interfaces in the category, consistent across web, desktop and mobile.
• A genuinely useful free plan, with Pro at a mid-pack price.
• Daily notes plus calendar integration make it a natural journal-of-record.

Worth knowing: No collaboration — explicitly not supported and not planned; sharing is read-only page links. Cloud-first and proprietary, with no local-first storage or end-to-end encryption. Power features like queries sit behind Pro, and the object model can feel like ceremony for quick, messy capture.

Which should you choose?

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.

Choose Capacities if:

• You think in entities — people, books, meetings — and want your tool to as well.
• Interface polish and aesthetics genuinely affect whether you’ll keep using a tool.
• You’re strictly solo and don’t need sharing or teamwork.

A third option: Dexi

If what you actually want is one searchable place for notes, bookmarks, newsletters and RSS — with tags, @mentions and [[wiki links]] that organize themselves as you write, semantic search that finds ideas even when the words don’t match, and an MCP server so Claude and other AI assistants can work with your notes directly — take a look at Dexi. It’s free for up to 1,000 notes, with no app to install.
