tldraw is an open-source infinite-canvas library and SDK, known for the "Make Real" demo that turns sketches into code. airsup is a ready-to-use AI canvas product that generates images, documents, tables, and interactive apps for builders. Here is how they compare.
tldraw is a canvas you build with; airsup is a product you build in. tldraw gives developers a beautiful open-source canvas to embed, plus AI experiments like Make Real. airsup is a finished workspace where anyone describes what they need and the AI generates multi-format assets, using their files as context, with accounts, projects, collaboration, and export built in.

tldraw is free to use in development and for hobby projects (with a "made with tldraw" watermark), but production and commercial use of the SDK requires a paid license that costs about $6,000 per year. airsup is a finished product at a flat $10/month (free to start), so there is no SDK to license or app to build.
Choose tldraw if you are a developer who wants to embed an infinite canvas into your own app, or experiment with canvas and AI at the code level.
Choose airsup if you want a finished product where AI generates the images, docs, specs, and apps for your project: no code, with uploads-as-context, projects, collaboration, and export built in.
