What it does

aiPDF is a web app for asking questions about documents. It accepts PDFs, EPUB books, website URLs and YouTube videos. Answers come with references taken from the uploaded files, and you can export the responses.

aiPDF is a browser tool for reading long documents without going through every page. You upload a file or paste a URL, wait for a short preprocessing step, then ask questions and get answers with references back to the source text. It supports PDFs, EPUB books, website URLs and YouTube videos, and responses can be exported. The free Playful tier allows 2 PDF uploads, 550 questions and a 35 MB maximum PDF size. Paid tiers raise these limits: Dynamic costs $9 per month with 120 PDF uploads and a 50 MB maximum, while Flagship costs $19 per month with unlimited PDF uploads and a 65 MB maximum. Documents are deleted after one month on Playful and after six months on Dynamic. Flagship keeps documents until you delete them. The app runs online, so there is nothing to download or install.
