PDF Summarizer

PDF Summarizer is a web-based tool for working with PDF documents. Users can upload image, PDF, or audio files, then receive detailed summaries, short summaries, key points, notes, flashcards, or quizzes. It offers multi-file chat so users can ask questions across several PDFs in one conversation, and a side-by-side view that links answers to specific parts of the document. The page states that documents can be translated into other languages, that uploads are limited to 50MB and 500 pages, that data is encrypted in transit and at rest with SOC2 Type II certified storage, and that the service is accessible from any device with a web browser. The FAQ says a free trial covers the first few messages, after which a subscription is required, and that no account is needed to start.
