UsePdfAi

Upload a lecture handout or a long report and ask questions about it instead of reading every page. UsePdfAi is an AI PDF chatbot and summarizer that answers questions about your documents and pulls out the key points.

It runs on GPT-4o mini across every plan, so the difference between tiers is about limits, not model quality.

The free plan is small: 2 PDFs a month, 10 pages per file, a 4MB size cap, one workspace and 10 questions in that workspace.

That is enough to test it on a short document.

The Pro plan costs $10 and raises the limits to 200 PDFs a month, 500 pages per PDF, 64MB files, unlimited workspaces, 1000 questions per workspace and priority support.

A Student plan at $5 sits in between with 50 PDFs a month, 200 pages per file, 16MB files, 50 workspaces and 100 questions per workspace.

If you work with long files or ask many questions, you will hit the free caps fast, and the Student plan looks like the cheaper step up for coursework.
