Offline OCR in your browser with layout-aware document recognition
Click the toolbar icon, draw a rectangle over any part of the active window, and the text inside is recognised immediately.
A Tesseract.js engine recognises plain text in over 100 languages with automatic text orientation and script detection.
Switch to IBM Granite-Docling to retain headings, lists, bold and italics, tables and mathematical equations instead of losing layout.
The OCR runs entirely in the browser with no server calls; only the language database is downloaded once and then cached.
AI sidebar and browser agent for reading, writing and research
A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.
