Questions about ocr pdf

Does OCR upload my document?

No. Recognition runs in your browser using WebAssembly. The only thing downloaded is the language model, which your browser then caches.

Why is the first run slow?

The language model (roughly 10–15 MB) is fetched once. After that, recognition starts immediately.
