Frequently asked questions

Is my document uploaded?

No — and it is worth being exact. On the first run your browser downloads the OCR engine (its worker script and WebAssembly core) and the recognition model for your language, roughly 2–15 MB in total, from a public CDN; all of it is cached afterwards. Those are one-way downloads. Your PDF travels the other way only — it is rendered and read inside this tab, so the document itself never leaves your device.

How accurate is it?

It depends on scan quality — clean 200+ dpi scans of printed text usually come out very well. We show the engine’s own confidence score with every result so you know how much proofreading to expect.

Which languages are supported?

English, Spanish, French, German and Portuguese. Pick the language before running — using the wrong model sharply reduces accuracy.
