Start with your project
Open the board you want to build on — an empty canvas is fine. Here it is a fresh project called 555 timer random blink led, ready for parts.
Describe it in plain English
Tap Share to AI, paste the prompt into Claude, ChatGPT, or any LLM, and just say what you want: make a 555 timer circuit that blinks an LED randomly. No part numbers, no schematic — the prompt already carries edit access to your board.
The AI gets oriented
It reads your current board, pulls the Circuitcaster manual, and picks the right parts — real datasheet dimensions, every pin named. You do not explain the format; it already knows it.
Watch it build — live
Components land on your canvas, get wired, and auto-route into clean traces as you watch. No refresh, no export back and forth — the AI edits your board in real time.
A complete circuit, ready to build
The finished 555 lands wired and labeled — GND, TRIG, OUT, VCC, DIS, THR — with its resistors, caps, LED and light sensor in a stocked library. From here it exports straight to KiCad and an orderable parts list.
Tip: library-first means every part carries a real part number — so your board is not just drawn, it is buyable.
