What AI PDF Reader is
AI PDF Reader lets readers ask questions about PDF files and trace answers to clickable citations on the exact page. Its reading tools include zoom, fit, rotation, continuous or single-page layouts, thumbnails, document search, text selection and copying, plus auto-scroll with a reading-speed tracker. Readers can highlight, underline, strike through, add notes and shapes, and bookmark pages; annotations and bookmarks are written into the PDF itself. The free path has no time limit. Pro adds OCR for scanned PDFs, whole-document summaries, questions across open PDFs, premium and multilingual models, and optional cloud providers. With a downloaded local model, extraction, indexing, retrieval and answering run on the device and continue offline. The maker says data is encrypted at rest, with a private encrypted copy of annotations and bookmarks kept on the device. Windows, macOS, iPhone and iPad are supported, and the interface is available in 16 languages. Personal costs $0.99 per month; Commercial costs $4.99 per month.
