What it solves

It provides a private, local-first whiteboard application that works without an internet connection, removing the need for accounts or servers while allowing users to save documents as portable files.

How it works

The app uses an infinite canvas for drawing, diagramming, and adding media. It saves documents in a native .tldraw format which includes the canvas, pages, and embedded scripts. It is designed to be compatible with coding agents that can inspect the canvas, modify it, and create scripts to add new behaviors to files.

Who it’s for

Users who need a local drawing and diagramming tool for privacy-conscious work, as well as developers and AI agent users who want a visual canvas that agents can programmatically interact with.

Highlights

• Local-first operation with no accounts or servers required.
• Cross-platform support for macOS, Windows, and Linux.
• Integration with coding agents like Claude Code and Codex to automate canvas changes.
• Portable .tldraw files that store both content and custom document scripts.
