Collate is a free, offline PDF assistant built for learners, students and professionals who would rather work through their own documents than upload them somewhere.
It summarizes PDFs, turning a long document into concise insights instead of demanding a full read. For anything a summary does not cover, you can chat with the PDF directly: ask questions, open a specific section, and pull out what you need without scrolling through the entire file.
Because it runs offline, documents stay on your own machine. There are no sign-ups and no restrictions on use, so every feature is available without creating an account.
