PdfGPT

What PdfGPT is

PdfGPT is a web service for reading PDFs, asking questions about them, and researching their contents with AI. It turns documents into organized study notes with headings, key terms, definitions, examples, section summaries, and page citations. Users can make spaced-repetition flashcards from terms and generate quizzes from notes. Deep Research can draw on several PDFs to create a unified set of notes, and OCR processes scanned handouts, photographed pages, and image-based PDFs. Notes are available in 10 languages and can be exported as PDF, Markdown, or plain text. The notes page accepts files up to 25 MB, and its free plan supports PDFs up to 500 pages, 25 notes per month, and five Deep Research reports. The free plan costs nothing; the Student plan is $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 plans let users choose a deletion schedule.
