Aircad brings professional CAD and AI into your browser tab

Aircad slipped into my browser tab while I wasn't looking, and now I'm not sure I want it to leave.

Aircad brings professional CAD and AI into your browser tab

The frustration that built Aircad is the same frustration that makes you wonder why a pair of sneakers costs $190 and ships next year, not tomorrow. It's the itch that says this should be better. The person who made Aircad looked at professional CAD, those expensive, slow-to-improve desktop beasts that charge extra for the privilege of showing a colleague your work, and decided the whole thing was broken in a boring, predictable way. So they built a browser tab that does NURBS-based solid modeling, reads DWG and STEP files, and drops a scripting API and an AI agent right into the workflow. No server-side lag. No toy-mode limitations. No separate PDFs that drift away from the source file. It is, in the most literal sense, the friend who already had a tab open on that.

This is the kind of tool that makes you circle back. You can compare it to the way Nike and LEGO's space sneakers: a yellow Air Max Dn for kids rethought a familiar silhouette for a new context, or how Corteiz and Nike trade secrets while the Shox R419 waits for its 2026 curtain let a collaboration breathe instead of rushing it to shelves. Aircad isn't a reissue or a slow reveal, it's a direct shot at the incumbents who have been coasting on inertia. The creator says current tools are expensive and slow to improve, and that new features barely move the needle. That's not a complaint; that's a diagnosis. And the cure is a browser tab that runs geometry locally, gives you real-time collaboration without an add-on subscription, and bakes AI into the scripting engine so you can write new commands that extend the tool itself.

Here is the concrete point you need to hold onto: Aircad's AI agent works with a stage-and-commit workflow. That means you see exactly what the AI is about to do before it does it. No black-box magic, no "trust me, it'll work." You can inspect the change, approve it, or reject it. That is the razor clam hiding in the spec sheet, the narrow detail everyone else scrolls past. Most AI in CAD is a plug-in that costs extra and runs opaque. Aircad makes the AI transparent and scriptable. You can use it to build repeatable, shareable workflows that your whole team can run. That is not a feature. That is a philosophy.

The open question is whether it can scale. The creator has built something that runs in a browser and handles professional-grade drafting, but the real test is whether it can handle the 2,000-part assembly that a desktop tool chokes on. That is the detail to watch. Aircad is live, it's weird, and it's fast. It surfaces fast and disappears if you're not paying attention. Stay spooty.

From Hacker News

Aircad is a professional CAD system running in the browser with deep AI integration. It includes professional grade drafting and documentation tools, NURBS-based solid modeling, and a lot more. You can make professional quality design documents with it. It is all integrated behind a scripting API that can do anything you can do in the interface and also perform complex modeling operations efficiently. It reads and writes file formats like DXF, DWG, STEP, and 3DM.
