JSON Schema Multi-Generator とは？

Hey hunters 👋 I'm Pasindu, the maker. Most JSON Schema generators use one sample and assume every field is required and every type fixed — almost never true for real APIs. Paste 2–5 real samples and this merges them: missing fields become optional, mixed types become nullable unions. A schema that matches reality, not one lucky response. 100% client-side, no signup, free. Part of jsondevtools.org. Feedback on the merge logic welcome — what JSON pain should I solve next?
