Integrity vs Tana: Supertags, Nodes, and AI Compared — Integrity

If you have spent any time with tools like Tana, the pitch behind Integrity will feel familiar and then, quickly, different. Both start from the same radical idea: there is no document, no separate database, no whiteboard app bolted on. There is only the node. A line of text, a heading, a task, a meeting, a card on a canvas — all the same underlying thing, nested in one tree. Integrity’s tagline is “keep the thread,” and that is the whole point: your work stays connected because it never leaves the outline.

Tana arrived at the node-first idea from the same direction. It is worth taking seriously, because it is genuinely good software, and because the two tools now differ less in their model than in where they have chosen to point it.

The shared foundation: everything is a node

In both tools, the atomic unit is a node, and nodes nest to form outlines. In Tana, “a node is the core unit of information” that can be linked, referenced, and nested within other nodes to form outlines. Integrity works the same way: you write a line, and that line is already a node. Fold it, drag it, indent it under another. Turn a line into a heading, a task, or a full document without converting anything — because there was nothing to convert. It was always a node.

This is the part people underestimate until they live in it. When structure is uniform all the way down, you stop managing containers. You stop asking “should this be a doc or a database entry?” You just write, and shape later.

Supertags: the same instinct, the same mechanic

Both tools solve structured data the same way, and it is the best idea either of them has.

In Tana, a supertag “turns a node into a typed object with a template of fields.” The documentation puts it sharply: unlike traditional tags that signal content is related to the tag, in Tana the content is the tag. Add a #task and the node gains fields like Status, Deadline, and Priority.

Integrity’s supertags do the same job. You tag a node and it becomes a row you can view as a board, a table, or a timeline. Crucially, it is still the same node — you are not copying it into a database, you are looking at your outline through a different lens. Change the node in the board and it changes in the outline, because they are one thing.

The difference here is subtle and mostly about surface area. Tana supports a mature set of views — Outline, Table, Cards, List, and Calendar. Integrity ships board, table, and timeline today. If your work is a wall of typed records that you slice a dozen ways, Tana’s view catalog is deeper right now, and that is a fair point in its favor.

Where they diverge

The interesting split is not the data model. It is what each tool decided to build on top of it.

Both have a spatial canvas — the difference is what a card is. In Integrity you pull nodes onto a canvas, arrange them, connect them, and drop sticky notes — and every card is still a live node from your tree, not a copy of one. Tana ships a canvas too: a “real-time collaborative canvas for diagrams, drawing, and visual thinking, with live cursors and linked graph content.” But Tana notes this was “challenging to deliver well in the outliner architecture,” so they “designed for it from scratch” as a separate surface that links back to the graph. Integrity’s canvas is the same nodes as the outline, seen spatially; Tana’s is a distinct surface that references them.

Integrity’s AI builds artifacts you can keep editing. Both tools have serious AI. Tana lets you “select from leading models from OpenAI, Anthropic and Google,” and offers meeting transcription without a bot, chat that references your notes, voice memos, live dictation, and image generation. That is a strong, model-flexible offering. Integrity points its AI at a different job: it reads your whole workspace and builds editable artifacts — a project plan, a slide deck, a database — as real nodes. The output is not a chat bubble you copy out. It lands in your tree, and you keep working in it.

Tana has moved toward meetings-first. Tana’s main site now describes an “agentic meeting platform” with a native, embedded video call and agents that “create documents, file issues, and update your context graph while you talk.” That is an ambitious, distinctive direction. Integrity also does meetings — it records, keeps a live transcript, uses your sparse notes as scaffold, and has AI write clean notes — but the meeting in Integrity is a node you reference later, one object among many in the same tree, rather than the center of gravity.

Side by side

A note on the canvas row: both products now ship a canvas. The distinction Integrity draws is unification — a canvas card is the same node as the line in your outline, not a linked copy — rather than the mere existence of a canvas.

Publishing and collaboration

Both tools let your work leave the app cleanly. Tana lets you publish a node as an interactive web page that anyone can view and navigate without a Tana account. Integrity publishes a page to the web too, and adds analytics on top, so a published plan or spec is also something you can measure.

On collaboration, Integrity’s sync is built on CRDTs — the lineage of technology that makes conflict-free multiplayer editing feel solid across the whole tree. Tana offers shared workspaces with member management and edit history, and recently added a real-time collaborative canvas with live cursors.

On integrations, Tana is currently the broader connector: GitHub, Linear, Slack, Jira, HubSpot, calendars, and an MCP server for external AI tools. Integrity ships Telegram and MCP connections today — enough to wire in an AI assistant like Claude Code and to capture from your phone — but it is the leaner surface. If you need to file issues into Linear from your notes tomorrow, Tana has you covered now.

Who should pick which

Pick Tana if meetings are the beating heart of your work and you want an agentic, native video call with AI acting during the conversation; if you want to choose your LLM per task across three providers; or if you need a deep bench of business integrations — Linear, Jira, HubSpot, Slack — wired in today.

Pick Integrity if you want one tree where writing, planning, spatial thinking, and structured data all live as the same nodes; if you want a canvas whose cards are the very nodes from your outline, not a separate surface; and if you want AI that reads your whole workspace and hands you editable plans, decks, and databases as nodes you keep shaping. If the appeal of the node-first model is that it never forces you out of the thread, Integrity is the tool built to keep it.

Both are honest attempts at the same good idea. The right one is the one whose center of gravity matches yours. For pricing and to try it, see integrity.sh.

Frequently asked

Are Integrity and Tana the same kind of tool?

They share a foundation: both treat every line as a node in an outline, and both let you tag a node with a supertag to turn it into structured data. They diverge on emphasis. Integrity keeps everything — including a spatial canvas — as nodes in one tree and leans on AI that builds editable artifacts as nodes. Tana has moved toward an agentic meeting platform with native, embedded video calls.

Does Integrity have supertags like Tana?

Yes. In Integrity you tag a node and it becomes a row in a database you can view as a board, table, or timeline — the same node seen through different views. Tana's supertags work on the same principle: tagging a node turns it into a typed object with a template of fields.

Which one has better AI?

It depends on what you want AI to do. Tana lets you pick among models from OpenAI, Anthropic, and Google and offers botless meeting transcription and chat over your notes. Integrity's AI reads your whole workspace and builds editable artifacts — plans, decks, databases — as real nodes you can keep working in.

Can I publish pages to the web from Integrity?

Yes. Integrity lets you publish a page to the web with analytics. Tana also lets you publish a node as an interactive web page that anyone can view without an account.
