WHY THIS EXISTS
Specialized workflow, inspectable result
Paste JSON or JSON-like LLM output and infer a Draft 2020-12 JSON Schema with nested objects, arrays, enums, required fields, and confidence notes. The scoring is visible and repeatable so users can improve an input, rerun the tool, and copy a useful artifact.

- Makes optional and enum assumptions visible.
- Outputs copyable schema instead of vague text advice.
