— A real Dim0 board
A Dim0 board showing nested research, sticky notes, code, charts, and an AI agent panelOpen inapp.dim0.net

Sticky notes, code, math, charts, sketches, and an AI agent — all on one board.

— The problem

One idea, five tabs.

Browse, note, sketch, ask AI, paste back. By the time you move forward, your thinking is spread across tools that never talk to each other.

— How it works

One prompt, work on the canvas.

The agent reads what's on your board, goes out and does the work, and drops the result where you're already thinking.

01 · READ

Reads the board

Starts from your actual workspace, not a blank chat thread.

02 · ACT

Searches, synthesizes, runs code

Parallel reasoning across sources. No tab switching.

03 · WRITE

Builds on your board

Nodes appear next to your notes. Editable, connected, live.

— Features

Built canvas-first. Agent native.

Most tools bolt AI onto a doc. Dim0 is built the other way around — the canvas is the interface.

Infinite canvas

Thinking, laid out in space.

Notes, code, math, and shapes on one infinite canvas. Nested boards keep big projects structured without losing the view.

Mapify

Notes become structure.

Select any notes and turn them into mind maps, schemas, or diagrams in one gesture. Mapify. Drawify. Schemify.

Board-aware AI

Reads first. Acts second.

The agent reads your board before it acts. Searches, runs code, writes results back as nodes you can edit and connect.

Code, charts, docs

Every kind of node, one canvas.

Sandboxed code nodes. Live widgets. Uploaded documents. Everything stays connected to the thinking that produced it.

— Rich notes

Notion-grade notes. Drawn on a canvas.

Tags, math, toggles, sub-pages, references, code. Edit by hand — or ask AI to draft and revise the note in place.

— Use cases

What it feels like to think on Dim0.

Four shapes of work that get faster the moment your tools share a canvas.

Turn a question into a map you can walk.
Learn

Turn a question into a map you can walk.

Ask anything. Get a structured mindmap on your canvas. Follow threads, keep your map, never lose where you were.

Pull benchmarks. Chart them. Annotate.
Research

Pull benchmarks. Chart them. Annotate.

Bring sources, run code, render charts. Compare results side by side without juggling tabs.

Rough shapes that the AI understands.
Sketch

Rough shapes that the AI understands.

Excalidraw-style freehand shapes, system diagrams, flows — drawn by you or generated. The agent reads them as context.

Long-form notes, spatially arranged.
Write

Long-form notes, spatially arranged.

Notion-grade rich notes — math, code, tags, toggles, sub-pages — sitting wherever you put them on the board.

— Themes

Six themes. Light and dark.

Parchment, Catppuccin, Tokyo Night, Gruvbox, Monokai Pro, Rosé Pine — pick the one that makes you want to open the app.

— Privacy

Your work is yours.

Use the cloud with nothing to configure, or run it yourself. Either way, your content stays yours.

No training on your boards

Your prompts, notes, and content are never used to train models — ours or anyone else's.

No ads. No profiling. No telemetry.

We don't sell data, we don't track your activity, we don't mine your work to target you. We make a thinking tool, not an ad business.

Self-host for total control

Open source, MIT licensed. Notes in pure Markdown. One-command Docker. Bring your own model keys if you want.

— FAQ

Questions, short answers.

A thinking canvas where notes, docs, code, widgets, and AI agents live on one board together. Rich notes like Notion, freehand shapes like Excalidraw, agents that act on the board — same surface.
Notion has rich notes but no canvas. Excalidraw has a canvas but no notes or AI. ChatGPT has AI but no spatial workspace. Dim0 has all three on one board — and the agent is board-aware, so it reads the surrounding context before it acts.
Yes, free to use during early access at app.dim0.net. The product is also open source — fork it, self-host it, bring your own model keys.
Yes. Inspect it, fork it, self-host it — it’s all on GitHub.

Today Dim0 is built for single-user thinking. Real-time multi-user collaboration is on the roadmap.
Dim0 runs in the browser today. Tablets work well; phones are read-friendly. Native apps may follow.
Complex thinking is spatial. A canvas keeps structure, relationships, and partial ideas visible at once. Chat buries context.
Read selected context, search the web, run code, and generate nodes, widgets, charts, or summaries directly on the board.
300+ active nodes in view stay smooth, with 1,000+ total supported per board.
On the cloud at app.dim0.net: prompts and board context are sent only to the model provider that produces the answer (Anthropic, OpenAI, Google, etc.) under their terms. We don’t train on your content, we don’t sell data, we don’t profile you for ads, and we run no behavioral telemetry on your boards. Self-host: everything stays on your infrastructure — local Postgres and vector DB, your own model keys, no calls back to us.
Pure Markdown. Download any note and paste it into any other editor — Obsidian, VS Code, plain text. Boards export cleanly too. No proprietary blocks, no vendor format you can’t walk away from.
