Hey PH 👋 We built TryJev because every team eventually hits the same wall: You’re classifying tickets / chat / urgency… and you’re paying a chat LLM to write paragraphs you don’t need, then parsing labels out of the prose. Jev (TypeSafe AI’s System One decision model) is the opposite interface: state + questions → typed answer + confidence + full probability distribution. TryJev is the unofficial playground so you can see that shape before you write a line of code: • Demo playground (no API key) • Quickstart via OpenRouter (typesafe/jev-1.13) • Scene library: ticket routing, intent detection, urgency • Guides: question design, confidence thresholds, Jev vs GPT Happy to answer anything about System One vs System Two, latency/cost tradeoffs, or how we gate low-confidence predictions to humans. Would love your feedback on the playground UX 🙏
