FAQ

PDF parsing is a highly challenging task, and most PDF parsing tools on the market are expensive. Immersive translation was the first to introduce a completely free local PDF document translation feature, benefiting millions of users, and this capability will remain free. However, this traditional local algorithm cannot effectively handle PDF documents containing formulas, tables, or images. To break through this limitation, we have created AI-driven PDF translation for Pro members, which utilizes the powerful recognition capabilities of artificial intelligence to accurately extract formulas, tables, and even content from scanned documents, making it particularly suitable for academic paper-type PDF documents. At the same time, with this advanced technology, we have also achieved perfect bilingual juxtaposition in PDFs, bringing a truly immersive translation experience to PDF documents.

If you: 1. Use Chrome; 2. Need to read a lot of English literature/PDFs/slides; 3. Are short on time or just want to skim; 4. Wish to have machine translation as a reference while conveniently browsing the original text, then anyone meeting at least two of these criteria should undoubtedly try this extension!
