Talk to your canvas. It draws back.

Spectacle is a spatial workspace for thinking and planning, with an AI that can create on the canvas.

Free & open sourceNo account needed

Demo: in Spectacle, a user asks the chat beside a canvas to draw the checkout flow from their Payments notes with a retry path for declined cards. The assistant shows which notes it is reading, replies, and draws an eight-step flowchart on the canvas as a proposal. The user applies it and the shapes become part of the canvas.

The canvas, reimagined.

A spatial toolkit for your hardest work. Powerful drawing tools, rich-text notes, diagramming, and small tools the AI builds for you.

  • Drawing tools

    Freehand ink, geometric shapes, and smart connectors that anchor and route cleanly around your cards.

  • Notes & to-dos

    Distraction-free markdown notes and to-do checklists that live directly on your canvas.

  • Extensions

    Small AI-built tools like converters, estimators, and checklists that live on your canvas.

An AI collaborator with hands on the canvas.

Most AI sits on the side and talks about your work. Spectacle's assistant shares the canvas: it reads what you're working on, places proposals in empty space, and waits for your nod.

  • It creates

    Full access to the same canvas tools to draw diagrams, clean sketches, and arrange real UI wireframes.

  • It sees what you see

    Understands your active canvas, displays context as removable chips, and pulls in references with @.

  • It keeps you in charge

    Every change lands as a proposal in empty space. Apply, edit, or discard without touching existing work.

Connect to other AI tools on your terms.

Claude Desktop, Cursor and other agents connect to Spectacle over MCP, so they can read the canvas you point them at and suggest changes to it.

  • Model Context Protocol

    Standard MCP server over a local Unix domain socket. Any MCP client can connect.

  • Explicit scopes per agent

    Grant access to one canvas, read-only or with permission to suggest changes. Revoke any time.

  • Changes stay as proposals

    Outside agents can't overwrite your canvas. Their edits land as proposal cards for you to apply.

  • Every call in the audit log

    See which tool read which note, at what time, right in the app. No mystery telemetry.

Private by design.
