SnapOCR - Screenshot & Text Extractor

About

SnapOCR — Screenshot any region, get the text in one click.

✨ WHAT IT DOES
Draw a box on any webpage. SnapOCR instantly extracts the text inside and copies it to your clipboard. No more retyping quotes from images, PDF viewers, video subtitles, error dialogs, or scanned documents.

🔒 100% PRIVATE — RUNS LOCALLY
Unlike cloud-based OCR tools, SnapOCR performs all recognition **inside your browser** using WebAssembly (Tesseract.js). Your screenshots and text NEVER leave your device. No account, no upload, no tracking.

🛡️ PERMISSIONS EXPLAINED
