The README opens with
Typed semantic decisions for TypeScript. Ask questions about your data, inspect the evidence, and decide what happens next using ordinary async/await or native Web Streams.
Define decisions with Zod 4 schemas or native typed question batches. Use Jev through TypeSafe AI or Vercel evaluation, or use Gemini, Claude, GPT and Gateway language models through the optional AI SDK generative adapter, without rewriting your questions. Add confidence gates, readable deadlines, explicit retries, replay and observability as your application grows.
