Every plan includes managed AI on frontier Claude models — no API keys to provision, no usage dashboards to babysit. The free tier is generous enough to design real boards, every month, forever.
A genuinely generous free tier. Design real boards with frontier AI — no credit card, no trial clock.
For engineers shipping boards every week. Ten times the AI budget, room for long agentic sessions.
For hardware teams that run on Cherry Blossom. Frontier capacity, our most capable models, direct access to us.
No account? No problem — use Cherry Blossom without one and bring your own Anthropic API key, with no limits from us.
Most “free tiers” are a demo with a fuse. Ours is the plan we expect most hobbyists to stay on: 2 million tokens a month covers regular design sessions — describing circuits, placing parts, fixing what the verification gate flags — with access to the same Claude Opus 4.8 that Pro gets. And because cached context counts at a tenth, long back-and-forth sessions on the same board barely dent it.
If you ever outgrow it, you can bring your own Anthropic API key and keep designing without limits from us — no account required — or wait for Pro. No lock-in either way.
The tokens the model actually reads and writes, straight from Anthropic's own usage reporting — no markup. Cached context is billed at just 10%, so long design sessions where the AI re-reads your board stay cheap.
It's a rolling 30-day window that starts the first time you use managed AI. When the window ends, your full quota is back — no proration, no surprise mid-month cutoffs.
Nothing breaks. Your designs, editor, and exports keep working — only managed AI requests pause until the window resets. You can also switch to your own API key and keep going immediately.
Always — and you don't even need an account. BYOK is free with no limits from us; you pay Anthropic directly. Managed AI just means zero setup: sign in and start designing.
