About AI PDF Reader
AI PDF Reader is a free, no-signup web tool that opens a document on screen while AI reads the whole file, summarizes it, translates it, and answers questions in the chat using only the document's own text. It handles PDF, DOCX, TXT, PPTX, EPUB, and FB2 files up to 30 MB, and uses OCR to read scanned or photographed pages. It's aimed at students, researchers, and professionals who need to quickly digest long reports, papers, contracts, or slides — and its main differentiator is that it's entirely free with no paid tier, no account, no page cap, and a side-by-side viewer for verifying every AI claim against the original.
