Model endpoint versus product boundary
Both can read documents. The difference is how much of the finished behavior you still need to build.
Bottom line
If you need a finished workflow boundary, LeapOCR is the better fit. If you want to work closer to the model, Mistral OCR has the stronger appeal.
LeapOCR
Built for the output your app needs
LeapOCR is designed around the handoff: markdown for humans, schema JSON for systems, and a smaller contract between the document and the workflow that follows it.
Mistral OCR
Built around the model call
Mistral OCR gives teams a capable OCR endpoint. That is useful, but it still leaves open questions around schema discipline, validation, response consistency, and how the output should behave across many document types.
