Frequently asked questions
How do I generate documentation from JSON?
Paste a sample and run the AI Copilot’s Schema + Describe action. It produces a JSON Schema with an AI-written description on every field, ready to use as docs.
How is this different from schema generation?
Schema generation infers structure and types; Schema + Describe adds a written description to each field, so the output doubles as human-readable documentation.
