AI & BYOK
Tostada's AI features are bring-your-own-key. You paste an Anthropic API key into Settings; it's stored in localStorage and only sent directly to Anthropic. Tostada has no server in between.
- Setting your key — where to get a key and how to save it
- Ask AI: generate tokens — the one AI hook live today, on Primitives
- Privacy — exactly what leaves your browser and what doesn't
What's live
| Surface | Status |
|---|---|
| Ask AI on Primitives — generate a palette from a prompt | ✅ UI live, stub mode by default (wiring deferred) |
| Suggest layout principles from a description | ⏳ deferred |
| Real Spread (rewrite-in-your-system) | ⏳ deferred |
| Drop a screenshot, get a token patch | ⏳ deferred |
Every AI surface has a manual fallback. The key gates AI-assisted shortcuts; nothing in Tostada requires a key.
Stub mode
When no key is set, the AI surfaces still work — they return deterministic mock responses. This lets you test the diff/apply/preview flow without paying for a call. Set a real key to switch to real responses.
