Document chat that stays anchored to your material
Upload a lecture PDF, a scanned handout or a set of slides and ask questions against that source instead of the open internet. Answers cite the section they came from, so you can jump back and check the original wording before you trust it.
- Works with multi-hundred-page textbooks — ask for one chapter at a time to keep answers precise.
- Ask for a plain-language explanation first, then ask for the technical definition; comparing the two is where understanding usually clicks.
- Follow-up questions keep the document in context, so you can drill from a summary into a single paragraph without re-uploading.
