Part of this entry was LLM-drafted and is being polished.
ChatPDF is the simplest PDF Q&A tool — upload, ask, get answers. Free tier covers small documents; $5/month for larger / more files. Browser-based, no install.
Editor's verdict
Cheapest in the category and that's the only reason to pick it. Quality is fine for short documents, drops on long ones (chunking gets fuzzy). For students / casual users on a budget, fair pick. For research-heavy work, NotebookLM is free and better.
Use cases
- chat with pdf
