What is aiPDF?
aiPDF is an AI-powered tool that lets you upload documents and start asking questions right away. It works with PDFs, EPUB books, website URLs, and even YouTube videos. You can summarize entire books, extract key insights, and get detailed answers with references pulled from your uploaded files.
To use it, you drop a file or paste a link. The AI preprocesses your document, and you can start chatting while summaries generate. It matches your questions to relevant sections, so answers are based only on the document's content. It supports all languages and responds in the language you ask in.
It suits students, researchers, professionals, and anyone dealing with long documents. The site mentions it's fun to use and gives back to environmental charities. There are file size limits depending on your subscription tier, and documents auto-delete after a month for the free tier.

Tips for better results with aiPDF
- Upload a complete PDF or EPUB instead of a partial file so aiPDF can match your questions against the full context and give references from the right sections.

- Paste a YouTube link directly into aiPDF to extract insights from a podcast or video, then ask targeted questions instead of watching the whole thing.
- Start chatting while aiPDF generates the summary, but wait for the preprocessing to finish before asking detailed questions to get the most accurate references.
aiPDF pricing
aiPDF has a free way to start, with paid plans for heavier use. Check aipdf.ai for current limits and prices.
What to check before you rely on aiPDF
- Check the file size limit for your subscription tier before uploading, since the website does not list specific size caps for free versus paid plans.
- Confirm how long your documents stay stored, because the free tier auto-deletes after one month, but the site does not state retention for paid plans.
- Verify whether your data is kept only as documents and login info, as the website says it stores only essentials but does not detail external database policies.
