Tldraw Offline

tldraw offline is a desktop whiteboard application for drawing, diagramming and sketching, built on the tldraw SDK that powers tldraw.com. It runs locally with no accounts and no servers, and works without an internet connection. Documents are saved as self contained .tldraw files that bundle the canvas, any images and videos, and custom scripts, so they can be backed up, kept private or shared with contacts. The AI angle is a bring your own AI model. AI agents such as Claude Code, Codex, Pi and OpenCode can see the open documents, make changes in the editor, and write reusable scripts that add new functionality to the canvas. The application does not bundle a model of its own; the user connects the coding agent they already use. It is aimed at people who want a private, file based whiteboard on their own machine and who want a coding agent to read and edit that canvas alongside them. A user manual and a changelog are linked from the site. The application is a free download for Windows, and the site does not list any paid plans.
