Frequently asked questions
How does Chat with PDF work?
Upload a PDF with selectable text, open the processed document, and ask a question in everyday language. CramDesk uses text extracted from your document to compose an answer.
Can I use a scanned PDF?
The PDF needs selectable text. An image-only scan may not contain enough readable content for analysis or chat.
Can I trust every answer?
No. AI can overlook a passage or answer incorrectly, even when it uses the extracted document. Check important claims against the original PDF.
Is there a page limit?
Paid plans allow up to 100, 200, or 500 pages per PDF, depending on the plan. Monthly page allowances also apply.
