JevTypeSafe is the playground for TypeSafe System One models — Jev and Laya. Classify text, route intents, score inputs, and test LLM guardrails with structured judgments (Choice / Yes-No / Score), not free-form essays. Export the same configuration to API, CLI, MCP, or skills. Sign up for 1,000,000 free input tokens (no credit card).
I built JevTypeSafe to make typed, structured text decisions easy to test in the browser. Try Jev and Laya, explore different judgment types, and tell me what workflows you’d like to build with TypeSafe System One.
