What PdfGPT is

PdfGPT is a web service for reading PDFs, asking questions about them and researching their contents with AI. It can produce structured study notes with headings, key terms, definitions, examples, summaries by section and page citations. Users can turn terms into spaced-repetition flashcards and generate quizzes from notes. Deep Research combines material from multiple PDFs into a shared set of notes, while OCR processes scanned handouts, photographed pages and image-based documents. Notes can be generated in 10 languages and exported as PDF, Markdown or plain text. The notes page accepts PDFs up to 25 MB, and the free plan supports documents of up to 500 pages. That plan includes 25 notes per month and five Deep Research reports, with no signup required to try it. The Student plan costs $4.99 a month, billed monthly. PdfGPT says files are encrypted in transit and at rest and are not used to train models. Free and Basic plan files are deleted every seven days; paid users can set a deletion schedule.
