AI Features FAQ

PDFAI uses GPT-4o from OpenAI and Claude from Anthropic. We choose the best model for each feature: GPT-4o for summaries and chat, Claude for academic content, and specialized models for flashcards and quizzes.

Yes, AI features (summaries, chat, flashcards, quizzes) require an internet connection because they use cloud-based AI models. However, scanning, OCR, search, and listening work completely offline.

Yes. Your documents are encrypted in transit, and we only send the text content needed for AI processing. We never store your documents on AI servers, and all data is processed securely. See our Privacy Policy for details.

Absolutely! PDFAI's OCR extracts text from scanned documents, then AI features work on that extracted text. You can scan a textbook page, paper notes, or any document, and immediately get summaries, chat, flashcards, and quizzes.

AI summaries and flashcards are highly accurate thanks to GPT-4o and Claude, but they're best used as study aids, not replacements for reading. Always review AI-generated content, especially for exams or professional use. You can edit any flashcard or quiz question.
