No cloud OCR request
The site is delivered as static files. After that, your selected image moves only between the page and a dedicated browser worker.
OCR without upload
Your image stays on your device
A genuinely local image-to-text tool: the worker reads pixels in your browser and returns editable text without sending either across the network.

Preparing private OCR…Editable result
Text will appear line by line.
A strict network boundary
A Content Security Policy limits connections to same-origin application and model files. There are no analytics, ad, account, or OCR endpoints.
Local does not mean mysterious
Progress labels show when the engine, detector, and recognizer are loading, and when text is being detected and read.
Offline after the first cache
Fast mode can work offline after its models finish caching. High accuracy works offline only after its optional model has also been stored.
