About AI PDF Chat

Reading a long PDF to find a single answer is time-consuming. AI PDF Chat lets you skip straight to the information you need by asking questions in plain English. Upload your document, and Claude Fable 5 — Anthropic's most capable model — reads it and answers any question you have about its content.

Claude Fable 5 is particularly well-suited to document Q&A. It understands complex language, maintains context across multi-turn conversations, and can interpret nuanced questions about legal language, technical specifications, financial data, and academic writing. You can ask it to summarise sections, explain terminology, compare clauses, or find specific figures buried in hundreds of pages.

Your PDF is processed on our secure server and the session data is held in memory only for the duration of your chat. Files are automatically deleted within two hours. Free users can send up to 5 questions per hour; Pro users get 50 per hour.
