ChatPDF

ChatPDF lets you upload a PDF and ask questions in natural language: summarize a contract, find a specific clause, pull figures from a financial report or have a memo reviewed. Unlike a general chatbot, the tool specializes on the document itself and cites source passages in its answers, making verification easy. No account is needed for free use, so it's quick to try for a one-off need.

The free plan limits use to 2 PDFs per day and 120 pages per document. A paid plan exists for heavier use, with volumes and pricing that have shifted over time; better to check the site directly before committing. The site claims multilingual support for documents and questions, making it usable in multiple languages. An API is documented for developers wanting to embed this function elsewhere, but the tool has no out-of-the-box third-party integrations (CRM, cloud storage): it's a standalone service.
