What AI can build · as of September 2026

See what's possible

If your picture of AI is a chatbot that writes decent emails, this page is for you. Everything here was built by AI from a prompt written in plain English, and it all runs right here in your browser.

Each piece comes with the complete prompt, so you can paste it into your own assistant and watch it happen. And each one explains what the model had to work out on its own: the parts nobody wrote down.

No. 01

Playable synthesizer

Soft Machine

A working synthesizer, rebuilt by AI from a prompt a public gallery published: a live oscilloscope, four knobs, a 16-step sequencer and a two-octave keyboard. Play it, copy the prompt, and see what the model had to work out that the prompt never mentions.

How these are made

I pick pieces from public galleries that publish their prompts, and have them rebuilt here from the prompt with Claude Code, adapted to this site's design. The code is new; the idea and the original prompt belong to the sources credited on each page. Each entry is dated, because what counts as impressive moves fast.
