Headline hook

`useSmartState` — typed AI state, in one line.

A drop-in useState that adds an ai.generate(context?) action. The runtime shape is read from your initial value, so the model is constrained to return JSON that matches — no JSON schemas, no parsers, no boilerplate.

const [user, setUser, ai] = useSmartState(
{ name: '', age: 0, bio: '' },
'a fictitious cyberpunk character',
);

ai.generate();        // → { name: 'Kael-9', age: 28, bio: '…' }
setUser({ ... });     // still works — full useState semantics

Every example below ships in two flavors — a Skeleton (bare API, unstyled) and a Stylized version using Tailwind. The hook is the same; only the wrapping markup changes. More advanced use cases live on their own pages — form autofill, extract from text, and color palette.

Why it's different

Shape-first

Seed an initial value; the prompt + JSON parser are derived automatically.

Cancel-on-edit

If the user calls setValue mid-generate, the in-flight request is aborted. Manual intent always wins.

Built-in cache

LRU(16) keyed by (shape, context) — repeated generates with the same context are free.

JS-compatible

No generics required. The runtime shape comes from the seed, so plain JS callers get the same behavior.

1. Primitive — random number

The simplest case: a number initial value plus a context string.
