AI document translation for PDFs, decks and books that keeps the layout
Translates the file itself, not extracted text, so tables, headings, columns, images and page structure stay where they were in the source document.
Scanned PDFs and image-based files are recognised with OCR and translated without you having to retype or rebuild the page layout.
PDF, PPTX, DOCX and EPUB are supported today, covering legal contracts, slide decks, reports, theses and full-length books.
Define how key terms must be translated so terminology stays consistent across a long project, a client account or a whole catalogue.
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.
