Frequently Asked Questions
How long a PDF can I summarize?
Up to 1,500 pages per file. Long documents are processed in chunks so nothing gets truncated — you still get one unified summary at the end.
Is this AI PDF summarizer free?
Free credits to start — no credit card needed. Paid plans add more credits, longer files, and access to premium models.
How accurate are the summaries?
Numbers, dates, named entities, and citations are preserved verbatim. For research and legal use, we recommend keeping the original PDF open to cross-check specific claims.
Does it work with PDFs in other languages?
Yes — upload a PDF in any major language and ask for the summary in the language you prefer. Spanish, Portuguese, German, Japanese, Korean, Arabic, and more are all supported.
Can I summarize scanned or image-based PDFs?
Yes. Built-in OCR extracts text from scanned pages and screenshots inside PDFs, so you can summarize old books, handwritten notes, and photographed documents.
What summary formats are available?
Executive summary, bullet-point key takeaways, chapter-by-chapter breakdowns, study notes, flashcards, and mind maps. Export to Markdown, DOCX, PDF, or plain text.
Is my PDF kept private?
Your documents are encrypted in transit and at rest, never used to train models, and can be deleted from your library at any time.
How is this different from ChatGPT or Claude for PDF summaries?
Genspark handles long PDFs end-to-end — up to 1,500 pages in one go — with built-in OCR, chapter-aware chunking, and direct export to notes and flashcards. No context-window workarounds, no manual splitting.
