What AI PDF Reader is
AI PDF Reader lets you ask questions about PDF files and follow citations to the exact page behind an answer. Its reading tools include zoom, fit, rotation, single-page or continuous layouts, thumbnails, document search, text selection and copying, plus auto-scroll with a reading-speed tracker. You can highlight, underline, strike through, add notes and shapes, and bookmark pages; annotations and bookmarks are saved in the PDF itself. A free path has no time limit. Pro adds OCR for scanned files, 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-device and continue offline. The maker says data is encrypted at rest and an encrypted private copy of annotations and bookmarks stays on the device. Windows, macOS, iPhone and iPad are supported, with an interface in 16 languages. Personal costs $0.99 per month; Commercial costs $4.99 per month.
