Scanned pages
Scanned pages, including copier scans whose text layer is weak or garbled, are read with the quick reader first (the AI tools run OCR PDF for you), so you get a result straight away. On computers that can run it, superPDF then offers high-accuracy reading beside the result, and improves those pages in the background: in Chat and Ask multiple PDFs the pages behind your latest question come first and new questions use the improved text; elsewhere, Run again with the improved text redoes the result. It runs on this device: nothing leaves it, and it works offline once downloaded. Download: 871 MB, once, only when you choose it; delete it any time in On-device AI models. Speed: about 10 to 30 seconds a page on a recent computer (the offer shows the time for your pages); up to 20 pages are read at a time unless you choose more or pick pages. It reads English and other European languages best; check results in other scripts, and like any OCR it can misread faded or handwritten text. Running page headers, footers and page numbers are left out of the text. If anything goes wrong, the quick result stays, with a short note. See High-accuracy reading.
Limits
superPDF sets no file size or page limit.
superPDF searches every document for the passages that match your question and gives the AI the best passage from each document that has one, so an answer spread over many pages of one document can be incomplete.
AI can be wrong, so check the result before you rely on it.
Privacy
Runs in your browser, with the AI you choose. With a model on this device, nothing leaves it. With your own API key (BYOK), the document text the tool needs goes from your browser straight to your provider, never through superPDF. See Privacy: AI features.
