PDF.chat
What it is
PDF.chat lets users upload documents, ask questions, and receive answers cited to exact pages in over 100 languages. It accepts PDFs, Word and PowerPoint files, text, and images, including PNG, JPG, WEBP, GIF, BMP, and TIFF. OCR models running on PDF.chat’s infrastructure can read scanned or photographed documents, and long files are indexed to retrieve relevant pages for questions about lengthy reports, textbooks, or dockets. Users can compare answers from Claude, GPT, Gemini, Llama, and DeepSeek side by side in one chat, then export results as plain text, Markdown, DOCX, searchable PDF, CSV, or JSON. It 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 a month and includes 750 pages monthly. PDF.chat says uploaded files are deleted shortly after processing and are not sold, shared, or used for training; on paid tiers, relevant passages may be sent to third-party AI providers.
