The big idea
Hand-typing TypeScript interfaces from API responses is busywork. Paste the JSON, ask the AI for the type, paste the type. The whole thing takes ten seconds and never has typos.
Some examples
- You paste a Stripe webhook JSON into Claude and get a clean type with optional fields marked correctly.
- ChatGPT turns a deeply nested API response into types with nested interfaces and union types for nullable fields.
- Cursor offers to add JSDoc comments to each field based on the API docs you pasted alongside the JSON.
- Copilot Chat generates a Zod schema and the inferred TS type from a single JSON sample.
Try it!
Grab any API response in your project's network tab, paste it into Claude, and ask for the TypeScript interface. Drop it in.
