Summary

PDF.chat lets users upload documents, ask questions, and receive answers tied to exact pages in over 100 languages. It accepts PDFs, Word and PowerPoint files, text, and images, and OCR models on its own infrastructure read scanned or photographed documents. Long files are indexed so questions can retrieve relevant pages from lengthy reports, textbooks, and dockets. Users can compare answers from Claude, GPT, Gemini, Llama, and DeepSeek side by side, then export results as plain text, Markdown, DOCX, searchable PDF, CSV, or JSON. The service runs in a browser without a download or installation. Its REST API ingests documents, returns per-page text and metadata, and supports chats with page citations; API use is metered per page. The free plan’s pages reset at midnight UTC. Starter costs 5.00 USD per month and includes 750 pages per month. PDF.chat says uploaded files are deleted automatically shortly after processing and are not sold, shared, or used for training; on paid tiers, relevant passages may go to third-party AI providers.
