Tana

Supertags are Tana's signature feature. Tag any bullet with something like #project or #person and the bullet automatically gains structured fields (e.g., status, owner, due date) that you define for that tag type. Everything tagged #project becomes queryable as a database — you can see all your projects as a list, filter by status, or group by owner. This lets your daily notes double as structured databases, without copy-pasting or maintaining separate systems.

For users who commit to learning it, yes. Plus unlocks unlimited nodes (vs 1000 on free), more AI credits, and shared workspaces for small teams. At $8/month billed annually, it is comparable to Notion with AI and cheaper than Roam. The value depends on whether you actually use Tana's supertags and AI features — for casual note-takers, simpler tools are cheaper and easier.

Different mental models. Notion is page-first with databases as structured pages you create. Tana is outline-first with databases that emerge from tagging bullets in your daily notes. Notion works better for wikis and structured team content. Tana works better for daily thinking, capture, and personal knowledge systems. Power users often describe Tana as "what Roam would be if it had Notion's database superpowers."

For committed power users, yes. One person can use Tana for daily notes (like Roam), task management (like Todoist), CRM (like Airtable), meeting notes (like Granola-plus-Notion), and knowledge base (like Obsidian). The caveat is it takes weeks of setup and ongoing maintenance to reach that point. Casual users almost always find it easier to use separate purpose-built tools, but for people who love configuring their own systems, Tana is the most ambitious all-in-one solution on the market.

Limited. As of early 2026, Tana is primarily online-first with weak offline support. The desktop app caches recent content but editing offline is unreliable. The mobile app is especially limited offline. If offline is critical, Obsidian or Logseq are much better. Tana has said offline support is on the roadmap but has not committed to a timeline.

For small teams of power users, yes. Shared workspaces on Plus and Pro plans support basic team collaboration on outlines and supertags. For larger teams or teams that are not comfortable with outliner interfaces, Notion is still the better choice — it has more polished collaboration, better permissions, public pages, and widespread familiarity. Tana works best for small teams where everyone is willing to invest in learning the tool.

Tana has deeply integrated AI including AI commands for rewriting and summarizing, automatic extraction of structured data from notes (e.g., turning meeting notes into tagged action items with owners and dates), AI-powered autocomplete, and chat with your workspace. Unlike tools where AI is a sidebar chat, Tana's AI is woven into the outlining experience — you can run AI commands on any bullet with a keyboard shortcut.
