Dim0
Dim0 is an open-source collaborative AI canvas where notes, mini-apps, and agents share one infinite board.
The architectural choice that sells Dim0 is where agent output lands: on the board as editable nodes, not in a scrolling chat pane. That single decision makes spatial context survive across sessions, and it's why we'd trial this over bolting ChatGPT next to Miro. The caveats are real — no documented third-party integration marketplace, no admin controls or SSO — so it fits individuals and small teams far better than enterprises.

Skip Dim0 if your team lives in linear documents and expects a mature third-party integration marketplace — its strength is the board itself, not plugging into the rest of your stack.
AI requests are capped on the free tier and the paid tier only raises that limit — heavy agent use is the variable that pushes you to upgrade.
The published structure is a free cloud entry point and a low-cost paid tier that raises AI request limits (€6.99/month per the seed data, though the pricing page was not reachable this run — verify current numbers before committing). For a single researcher or a small team it undercuts per-seat canvas tools by a wide margin; the comparison flips only if you need enterprise admin controls or a large integration catalog, where Miro and Notion charge for things Dim0 does not yet publish.

About Dim0
Dim0 is an open-source, MIT-licensed AI canvas that treats the board itself as the interface. Notes, code, math, images, hand-drawn shapes, docs, widgets, and nested folders all live on one infinite surface as first-class nodes — and the AI can read every one of them. The agent reads your whole board before it acts, then searches the web, runs code in a sandbox, and writes results back as editable nodes next to your notes instead of burying them in a chat sidebar. Describe a calculator, chart, or quiz and Dim0 drops a real interactive React mini-app onto the board. Group work into nested boards that fold like folders, turn frames into slides with presentation mode, and use Mapify to convert notes into mind maps, schemas, or diagrams in one gesture. Rich notes cover tags, math, toggles, sub-pages, and code, edited by hand or drafted in place by the agent. Real-time multiplayer brings live cursors, names, avatars, and presence colors, plus shared agents where one person prompts and the whole room watches and refines. Edits sync through operational transforms with last-write-wins — the same approach Figma and Excalidraw use — so two people can edit the same note without merge conflicts. It suits researchers, developers, writers, and privacy-first teams who want a Miro-style canvas they can run themselves. Eight AI providers are supported (Claude, OpenAI GPT, Gemini, Mistral, DeepSeek, Qwen, Kimi, ChatGLM), self-hosting runs on local Postgres and a local vector DB with your own model keys, and notes are pure Markdown so boards export cleanly. Where Miro and Notion keep your thinking in their cloud, Dim0 hands you the codebase.
Behind the Verdict
Most canvas tools bolt AI onto a doc and call it done. Dim0 went the other direction: the canvas is the interface, and every node type is something the agent can read. We'd reach for this when the shape of the thinking matters — literature maps, architecture sketches, prototype pipelines — because the agent reads the whole board before acting and drops results back where you're already looking. Pick it if you want data custody the big canvas vendors don't offer. The codebase is public and self-hostable, with local Postgres, a local vector DB, and your own model keys. On the cloud side it's TLS on the wire, at-rest encryption on the database and uploads, no training on your boards, and no session replay on the canvas. Notes are pure Markdown, which means no proprietary export to fight later. Pass on it if your team lives inside linear documents. Dim0 is a canvas first; if you need Google-Docs-style flow, page-by-page editing, or comment threads on paragraphs, this will feel upside down. Same for teams whose workflow depends on a large integration marketplace — none are documented on the vendor page. And if you require formal admin controls, SSO, and a support contract, that's not what you're buying here. The closest alternative is Excalidraw, which gives you the infinite canvas and the openness but no notes and no board-aware agent. Miro has the canvas and the ecosystem but keeps your boards in its cloud. Notion has the notes and the ecosystem but no canvas. Dim0's pitch is that you stop choosing. Where it bites in practice: self-hosting is a real ops task, not a toggle, and running local Postgres plus a vector DB is on you. Shared agents are genuinely collaborative but they also mean a prompt from one teammate consumes one shared model quota, so the "one person

Real-world workflow fit
Concrete scenarios for the personas Dim0 actually fits — and what changes day-one when you adopt it.
You drop six PDFs onto a new board, tag the notes you pull from each, then ask the board-aware agent to synthesize themes across them; Mapify converts the resulting note cluster into a mind map you can rearrange by hand.
Outcome: A literature map that lives on one canvas, with the AI's synthesis sitting as editable nodes next to the source notes rather than in a chat log you have to scroll back through.
You describe a small calculator or chart widget, get a React mini-app on the board, then open a code node beside it to wire in real data and run it in the sandbox.
Outcome: A working prototype on the same board as the design notes, with no context switching to an editor or a terminal.
You open a shared board, place frames around the sections of a product idea, prompt a shared agent while teammates watch and refine the output, then switch to presentation mode to walk through the frames as slides.
Outcome: A brainstorm and a presentation produced from the same canvas, with no export-and-rebuild step and no merge conflicts as people edit simultaneously.
Use Cases
- Map a literature review spatially, then have Mapify turn your notes into a mind map of themes.
- Prototype a data analysis pipeline with live code nodes and chart nodes on one board.
- Brainstorm product features with a remote team using shared agents and live cursors.
- Describe a quiz or calculator and get a working React mini-app placed next to your notes.
- Synthesize multiple PDFs and web searches into a structured summary node.
- Sketch a system architecture by connecting code snippets, diagrams, and agent-generated components.
- Build a slide deck by framing existing board content in presentation mode instead of exporting.
- Self-host the whole workspace on your own infrastructure with your own model keys.
Models Under the Hood
as of 2026-10-18
Limitations
- Dim0 is an open-source, MIT-licensed canvas that you can use on the web or self-host, but self-hosting asks for genuine technical comfort since you supply local Postgres, a vector DB, and your own model keys.
- The board-aware agent's usefulness scales with how much you put on the board — a sparse canvas gives it little to read.
- The live site advertises 8 AI models but does not enumerate per-provider capability differences, so you should test your preferred model against your own tasks.
- Real-time collaboration and shared agents are built on operational transforms with last-write-wins, which is a sound default but means a simultaneous edit to the same node resolves to one writer rather than merging both.

$0/mo
Ideal for
A solo researcher, developer, or writer trying the canvas-agent workflow before committing any budget, or anyone on the fence about whether a spatial workspace beats their current tabs.
What this tier adds
Starting tier: free cloud access with nothing to set up and no card required, but AI request limits sit lower than the paid tier.
Basic
€6.99/mo
Ideal for
A regular user whose board-aware agent usage has outgrown the free request limit and who wants the full canvas, notes, mini-app, and collaboration feature set.
What this tier adds
Raises the AI request limit on top of all core features — canvas, notes, mini-apps, and collaboration — and can be started from your account whenever you hit the cap.
Where the pricing makes sense
The company stage and team size where Dim0's pricing actually pencils out — and where peers do it cheaper.
The published structure is a free cloud entry point and a low-cost paid tier that raises AI request limits (€6.99/month per the seed data, though the pricing page was not reachable this run — verify current numbers before committing). For a single researcher or a small team it undercuts per-seat canvas tools by a wide margin; the comparison flips only if you need enterprise admin controls or a large integration catalog, where Miro and Notion charge for things Dim0 does not yet publish.
Setup time & first value
How long it actually takes to get something useful out of Dim0 — broken out by persona, not the marketing-page minute.
Cloud: minutes — the site advertises free-to-start with nothing to set up, and you can pick a model and start placing nodes immediately. Team: add collaborators and the shared board works the same way for one person or fifty, so onboarding is a matter of inviting people rather than configuring anything. Self-hosted: plan on a real project, since you provision local Postgres and a vector DB and
Switching to or from Dim0
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From Miro: rebuild boards as Dim0 canvases and gain the board-aware agent and MIT-licensed self-hosting that Miro doesn't offer.
- →From Notion: export pages and re-place them as rich note nodes on a canvas, then let Mapify turn page hierarchies into mind maps.
- →From Excalidraw: import your drawing habits directly — Dim0 uses Excalidraw-style freehand shapes — and add notes plus a board-reading agent around them.
- →From a ChatGPT-plus-notes workflow: stop pasting answers between tabs and let the agent write results back onto the board as editable nodes.
- ↗To Notion: export notes as Markdown, since Dim0 stores notes in pure Markdown with no proprietary format.
- ↗To Miro: export boards as data and rebuild on Miro if you need a mature integration catalog and formal admin controls.
- ↗To Excalidraw: hand-drawn shapes carry over conceptually, so sketch-heavy boards move with little friction.
- ↗To self-hosted Dim0: run it yourself with local Postgres and a vector DB and your own model keys if you want to stop using the cloud.
