Edit a real part right now. No account, nothing to install.

This is the SpeakCAD editor itself, with a print-ready part already generated from the prompt you see in the chat. Ask for a change in plain English (“make the lip 4 mm taller”), or click a part of the model and type a new number, and watch it rebuild in your browser. It runs on a phone too. The demo runs on the quick model and allows 3 small edits; describing your own part, the stronger models, uploads and downloads come with credits, from Maker at $7.99 a month for 50 credits, cancel anytime.Tap a face or ask for a change, right below.

Live demo

What you can do hereTap a face and add a hole, a cut, a tab or rounded corners with the hand tools (free, as many as you like), change any dimension by chat or by clicking the model, undo and redo, compare with the ghost of the previous version, orbit and inspect the mesh, and read the printability check. Every rebuild is real OpenSCAD geometry compiled in your tab.

What credits addYour own parts from a description, the model picked for each request (deeper reasoning for new parts and redesigns, a stronger model whenever an answer misses), photo, STL, 3MF and .scad uploads (4 credits for a new part on a plan, its first 3 small changes free, 3 for a redesign), edits for 2 credits each (1 for a quick edit), and downloads of the STL, 3MF or G-code sliced for your printer. Start with Maker: 50 credits a month for $7.99, cancel anytime; Pro brings 200 credits a month. Downloads, sliced G-code included, come with both.

The parts in the demoOne of 4 is loaded at random: ESP32 enclosure with snap lid, AirTag keychain holder, drawer organizer tray, 60° phone stand with cable slot. Each was generated from the one-sentence prompt shown at the top of the chat, exactly as a subscriber would type it. Press “Another part” to load a different one.

Questions about the demo

Yes. The live demo on the homepage (and at speakcad.com/demo) is the real editor with a real part already loaded: an ESP32 enclosure, an AirTag keychain holder, a drawer organizer tray or a phone stand, picked at random. Edit it by chat (“make the lip 4 mm taller”) or click a part of the model and type a new number, and watch it rebuild in your browser. No sign-up, no card, nothing to install; it works on a phone too. The demo allows 3 AI edits of that part; describing your own part, the stronger models, uploads and downloads need an account with a plan, from Maker at $7.99 a month.

The demo edits one pre-made part on the quick model, 3 times, and nothing can be downloaded. A plan unlocks the full editor: describe any part from scratch, let SpeakCAD pick the model for each request (deeper reasoning works through the geometry of new parts, and a stronger model steps in whenever an answer misses), attach photos, STL, 3MF or .scad files, iterate in the chat, and download the STL, 3MF or G-code sliced for your printer. Maker is 50 credits a month for $7.99, Pro 200 credits a month; cancel anytime.

The demo runs on the quick model, good at changing sizes, holes and tolerances of an existing part, and cheap enough to run for anyone who passes by. New parts and redesigns get deeper reasoning, which thinks through the geometry for a minute or more, and a stronger model whenever an answer misses; that is what a plan is for. The demo tells you when a request crosses that line instead of quietly producing something worse.
