aiPDF

What is aiPDF?

aiPDF is a browser-based app for talking to your documents. You upload a PDF, an EPUB book, a web link or a YouTube video, and the AI preprocesses it, writes a summary and lets you ask questions in a chat. Answers are matched to the relevant passages and shown with references so you can verify them, and it replies in the language you write in. Scanned files are handled through OCR, you can combine several documents into one multi-document chat, and responses can be exported or shared as a downloadable chat. The vendor says documents are stored encrypted, that data sent to the AI is excluded from external model training, and that you can delete files at any time; automatic deletion happens after one month on the free tier and six months on Dynamic. Nothing needs to be installed. The Playful tier is free, Dynamic costs $9 per month and Flagship costs $19 per month, with custom pricing for Enterprise.
