Integrity vs Obsidian: AI-Native Outliner vs Local Markdown Vault — Integrity

Two tools, two philosophies. Obsidian treats your knowledge as a folder of Markdown files you own on disk, then lets you extend the editor with plugins until it does almost anything. Integrity treats your knowledge as a single tree of nodes — every line, heading, task, canvas card, document, and meeting is the same kind of object — with AI that reads all of it and builds things for you.

Neither approach is wrong. They are aimed at different people, and the honest way to choose is to understand what each one refuses to compromise on.

What Obsidian gets right

Obsidian’s core promise is durability and ownership. Your notes are plain Markdown files stored locally on your device, in a folder you can open, back up, and read with any text editor for the next twenty years. That is a real guarantee, and it is the reason people trust it with a decade of writing.

On top of that foundation, Obsidian is deeply extensible. A large community plugin ecosystem lets you reshape the app into an outliner, a task manager, a spaced-repetition system, or nearly anything else. It ships a graph view that maps the links between your notes, a Canvas — an infinite board where you arrange notes and cards spatially — and Bases, a core feature that turns your notes into database-like views. The base app is free for personal use, with optional paid add-ons for syncing across devices and publishing notes to the web.

If your instinct is “I want to own my files and assemble my own tool,” Obsidian is one of the best answers available. Integrity is not trying to beat it at that game.

Where Integrity is different: everything is a node

Integrity starts from a different axiom. There are no files. There is one tree, and everything in it is a node.

A node can be a line of text. Fold it and it holds children. Turn that same line into a heading, a task, or a full document without copying it anywhere — it is the same node, wearing a different shape. Drag it and its subtree moves with it. This is the outliner at the center of the product, and it is not a plugin you bolt on. It is the substrate.

Because a task and a paragraph and a section are all nodes, the usual walls between “my notes app,” “my docs,” and “my to-do list” disappear. You are always working in one structure. The tagline is keep the thread — the idea that the connection between a rough note, the task it spawned, and the document it became should never be broken by moving between apps.

Supertags turn nodes into databases

The sharpest structural difference is supertags. In Integrity, you tag a node and it becomes a row in a database. The same node can then be viewed as a board, a table, or a timeline — you are not making copies, you are looking at one node through different views.

That means a meeting note tagged as a decision, a line tagged as a bug, and a heading tagged as a project all become structured, queryable rows without leaving the outline.

Obsidian ships Bases, a core feature that turns your notes into database-like views: each note becomes a record, its properties become columns, and you can lay the results out as a table, cards, a list, or a map. It is a genuine native database — but it works at the note level, so the record is a whole file. Integrity’s supertags work at the node level: a single line, task, or heading inside a document becomes a row, and the very same node is what you see on a board, in a table, or on a timeline.

AI that builds, not just chats

Obsidian ships no built-in AI assistant — neither its shipped nor its planned feature list includes one. Its native app is a Markdown editor with a graph, Canvas, and Bases; AI arrives through community plugins that you install, wire up to a model, and maintain.

Integrity’s AI is native and structural. It reads your whole workspace and produces editable artifacts — a project plan, a deck, a populated database — as real nodes in your tree. The output is not a chat transcript you copy out. It is an outline you can fold, drag, re-tag, and hand to a collaborator, because it was made of the same nodes as everything else. You can also connect external AI assistants through MCP, so a tool like Claude Code can work against your workspace directly.

Meetings become nodes

Integrity records a meeting with a live transcript, uses your sparse notes as scaffold, and then writes clean notes for you. The meeting itself becomes a node you can reference later — link a decision from it into a project, or fold it under the initiative it belongs to. Obsidian has no native meeting capture; recording and transcription come from community plugins, or you reach for a separate tool and paste the result in as text.

Publishing and collaboration

Both tools can put a page on the web. Obsidian offers Publish, a paid add-on that turns selected notes into a hosted site. Integrity lets you publish a page and gives you analytics on it, and — importantly — your workspace is collaborative in real time through CRDTs, so multiple people edit the same tree at once. Obsidian is local-first at its core; cross-device use and shared vaults come through its paid Sync service, and real-time multiplayer editing is on its roadmap rather than shipped.

Side by side

Who should pick which

Pick Obsidian if owning your data as plain files is non-negotiable, if you work mostly offline and solo, and if you enjoy assembling your own tool from a plugin ecosystem. The local Markdown vault is a genuine, lasting advantage, and no amount of AI changes that trade-off. If you would be uneasy trusting your notes to a system without files on disk, Obsidian is the honest choice.

Pick Integrity if you want structure and AI to be native rather than assembled. If you want one tree where a note becomes a task becomes a database row becomes a canvas card without ever leaving the outline; if you want AI that reads everything and hands back editable plans, decks, and databases; if your meetings should turn into referenceable nodes; and if you want to collaborate in real time — Integrity is built around those things from the ground up.

The deciding question is simple. Do you want a durable local vault you extend yourself, or a single AI-native tree that keeps the thread across notes, tasks, meetings, and databases? For pricing and to try it, see integrity.sh.

Frequently asked

Is Integrity a drop-in replacement for Obsidian?

Not exactly. Obsidian is a local-first Markdown editor you own on disk and extend with plugins. Integrity is a collaborative, AI-native outliner where every line, task, and canvas card is a node in one tree. If your priority is offline plain-text files, Obsidian is a better fit. If you want AI that reads your whole workspace and builds editable artifacts, Integrity is built for that.

Does Obsidian have built-in AI?

No. Obsidian ships no native AI assistant — its shipped and planned feature lists include none. The core app is a Markdown editor with a graph view, Canvas, and Bases; AI features come from community plugins you install and configure yourself. Integrity's AI is native: it reads the whole workspace and creates plans, decks, and databases as editable nodes.

Can I keep my notes as local files with Integrity?

No. Integrity stores your workspace as a shared tree of nodes with real-time CRDT collaboration, not as Markdown files in a folder you control. Obsidian's defining feature is exactly that local vault. This is the clearest trade-off between the two.

Do both apps have a canvas?

Yes. Obsidian ships Canvas, an infinite board where you place notes and cards. Integrity has a canvas too, but the cards on it are the same nodes as everywhere else in your outline, so a canvas card and an outline line are two views of one thing.
