What it does

AskYourPDF is the most popular PDF chat tool outside of ChatPDF. Upload a PDF (or link a URL to a paper, contract, or manual), ask a question, and get a cited answer with the exact page references. It also has a Chrome extension and a GPT/custom GPT integration so you can use it from anywhere.

Who it's for: Students, researchers, lawyers, and anyone who reads 50+ page PDFs regularly and wants to extract insights without re-reading. Especially good for literature reviews and contract review.

Key features

PDF Chat with any PDF

Drop a PDF or paste a URL — get a 3-sentence summary, key claims, and the ability to ask follow-up questions. Every answer cites the page.

GPT ChatGPT integration

Use AskYourPDF as a plugin/action inside ChatGPT — chat with PDFs from the ChatGPT interface you already use.

Chrome Chrome extension

Right-click any PDF on the web and chat with it without downloading. Perfect for arxiv papers, government PDFs, and online manuals.

Multi Multi-PDF chat

Upload up to 10 PDFs (Pro) and ask cross-document questions — 'compare the methodology in papers A and B.' Best in class at this use case.

The honest take

✓ What works

Free tier is generous (100 pages/mo) — beats ChatPDF's 3 docs/mo
Multi-PDF chat (compare across documents) is excellent
ChatGPT plugin is well-built — feels native, not bolted on
Cited answers — every response has page references, which is essential for research
Works on scanned PDFs via built-in OCR

✗ What doesn't

Accuracy drops on long PDFs (>200 pages) — chunking artifacts
No table/figure understanding — ask about a chart and it gives you text only
Pricing jumps at the Pro tier ($15/mo for 5,000 pages)
Mobile experience is web-only — no native iOS/Android app

Verdict

AskYourPDF is the best all-around PDF chat tool in 2026. It beats ChatPDF on free tier generosity and multi-PDF support. If you regularly read research papers, contracts, or long reports, the $15/mo Pro plan pays for itself in saved re-reading time. For pure PDF chat inside ChatGPT, the plugin integration is the best in class. The only thing missing is chart/table understanding — for that, dedicated tools like Humata are stronger.
