Guide
A practical guide to reading, annotating, and reviewing lecture PDFs without creating a fragmented study process.
A lot of students break their study flow by starting with a blank document and only occasionally looking back at the lecture slides.
A cleaner method is to begin with the original PDF and keep your notes attached to the slide that created the question in the first place.
For each slide, capture the one thing that matters most: the definition, relationship, formula, process, or contrast the professor is trying to teach.
That keeps notes short enough to review later while still preserving meaning.
AI is most valuable when it helps you cross the gap on a difficult page after your first pass through the file. It is less useful when you already understand the slide and only need a short note.
KeepUpClass works best when AI explanations act as targeted follow-up support within a study flow that stays tied to each page.
Keep exploring the guides and study flows that fit the way you review lecture materials.
