Open the editor and describe the board — the AI is included from Pro up, with no API key to set up. Claude designs while the verification gate checks.
trycherryblossom.com/app opens the editor with no install. You start on an empty 50 × 50 mm board called Untitled Circuit.
Your projects are saved to your account, so the editor needs to know whose they are. Type your first prompt whenever you like — pressing send asks you to sign in. A free account gets the whole editor to design by hand. The agent is included from the Pro plan up — 600 AI actions a day — and there are never third-party credentials to provide.
Open the AI Assistant with the chat button or Ctrl/⌘ L and describe what you want to build. Try “Design a 555 timer LED blinker” or “Add an ESP32 with USB-C power”. Claude edits the circuit live while it finds parts, footprints, and datasheets.
After every AI edit, the gate reports either Circuit validated: no errors or a concrete issue such as an unconnected pin or missing footprint. It does not auto-fix; ask Claude to address each flag.
Switch between Schematic, PCB, 3D, and BOM tabs. The PCB view includes select, move, route, autoroute, and a DRC inspector. Want the raw source? Settings → Advanced → Show Code tab reveals the circuit's TSX.
Select Export for a KiCad project, Circuit JSON, or a BOM CSV — open formats, so the board leaves with you. There is nothing to save by hand: the agent writes every change straight to your account.
The editor is free to use by hand. Managed AI is included on Pro and Ultra, with no API key to connect. Pro gets 600 AI actions a day and 4M credits a month, and Ultra is 8× that plus the frontier model (Sakura 2 High). Both can turn on on-demand usage to keep working past the included allowance at $5 per 1M credits. The chat explains when you reach a limit and when credits reset.
Your projects live in your Cherry Blossom account, so a design is there on any machine you sign in from. They are private to your account, and Export takes a copy out at any time in open formats.
This is an early beta with weekly releases. Tell us in Discord if something breaks — and keep an eye on what the agent builds before you send a board to fab.
