What it does
The playground shows source evidence and probabilities. Mapping is experimental and answers can vary; images stay as links, and references, files and custom validators are unsupported. Markdown goes to TypeSafe or OpenRouter.
Integrations
Vellum
Vellum asks Jev which Markdown blocks belong in a Sanity document, then copies and validates those source values in ordinary code.

How you can use it
If your team moves articles into Sanity, a system for storing website content, ask a developer to examine Vellum’s mapping idea. It chooses where existing source blocks belong instead of inventing missing text. Keep the source beside each suggestion so an editor can check it before accepting a document change.
The prototype needs a server-side service key and sends Markdown text to TypeSafe or OpenRouter. Missing required fields still need attention, and references, files and custom checks are not supported. Start with permitted sample documents and compare the suggested fields with the answers your editors expect.
