About this tool
Generate TypeScript interfaces and Zod validation schemas from JSON with nested types and enum inference. AI JSON Type Inferencer runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.
What this tool does not do
- AI JSON Type Inferencer is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.
