PDF Suite by Function Labs

Ask questions about your PDF

Read your document alongside an AI assistant. Generate a summary, pull out key points or ask a specific question. Check important answers against the original PDF.

AI is included in the one-time premium trial when available, the day pass and Pro. Direct uploads need selectable text (up to 50,000 characters); image-only scans need OCR first. Questions can be up to 1,000 characters.

Common questions

Is AI always accurate?

No. AI may omit details or make mistakes. Verify important points in the source document.

Do I need to save my document first?

No. Direct PDF selections remain in this tab. Extracted text is sent for the AI task but is not saved to a document-library record.
