Questions for a week's notes
Lecture material arrives in whatever shape the module handed you: slides exported to PDF, a printed handout you photographed on the way out, the notes you typed with one ear on the lecturer. Any of it can sit beside a chat and be asked about. What did week six actually establish. What does that abbreviation on slide fourteen stand for. Which of the four models did the deck spend most of its time on, and which got a single line. Each answer names the page it came from and the viewer jumps there, so a quick question ends with you looking at the slide rather than at a summary of it. With notes you wrote yourself that round trip is often the whole point: you remember writing the line, you just cannot remember what it meant.
Incomplete notes are the normal case, and that is where a refusal to guess earns its keep. The assistant answers from the file and nothing else, so when your notes stop mid-sentence because the lecturer had already moved on, you are told the answer is not in the document instead of getting a confident reconstruction of a lecture nobody recorded. Used deliberately, that turns a thin deck into a short list of things to chase: two definitions to borrow from a coursemate, one derivation to look up in the textbook, one topic to raise in a tutorial. Asking whether a proof appears anywhere in these slides and getting a clear no is a useful answer. It is the difference between a gap you know about and a gap you meet in the exam.
What you get, on every document
- Answers that cite the page
- Replies name the pages they came from, as chips that scroll the viewer straight there so you can read the source yourself.
- Grounded in your document
- It answers from the file you uploaded and says so plainly when your question is not covered, rather than inventing something plausible.
- PDFs up to 25 MB
- One document per chat, shown beside the conversation with real text selection — highlight a passage and ask about that exact part.
- Scans read automatically
- Pages with no selectable text are read with OCR instead, page by page, so a scanned or photographed document still works.
- Six interface languages
- English, Bangla, Spanish, Indonesian, Arabic and German — and replies come back in whichever language you ask in.
- Turn it into practice
- The same document can become practice multiple-choice questions, spaced-repetition review and mock exams once you have read it.

Lecture notes FAQ
Can it help me catch up on a lecture I missed?
Within one limit: it reads the file, not the room. If a coursemate shares full notes, or the lecturer posts an annotated deck, you can ask what was covered, what a term means and how one slide leads into the next. If the deck is four bullet points a slide, you will be told plainly that the detail is not there, which at least converts a missed lecture into a specific list of things to ask about.
Do the page numbers match my slide numbers?
Not always. The reference names the PDF page, and a handout printed six slides to a page puts slides seven to twelve on page two, while a title page shifts the whole count by one. It rarely matters while you are working, because clicking the reference scrolls the viewer to the right place regardless. If you are quoting a slide in an essay, use the number printed on the slide itself.
Can I ask about one line on a slide rather than the whole deck?
Yes, where the file carries real text: select the line in the viewer and ask about that selection, and the question is anchored to the sentences you picked instead of to the deck in general. It is the quickest way to deal with a step in a derivation that refuses to resolve. A photographed handout has no selectable text, so there you type the question and name the page instead.
