Problem
- Students wrestle with 200-slide decks the night before exams.
- Sharing notes across group chats meant zero version control.

What I built
- Uploads PDFs, chunks them, and streams summarized notes with references.
- Per-user libraries powered by Prisma/PostgreSQL so classmates can revisit packs.
- Usage dashboards that log token costs, latency, and retries for every request.
Outcome
- 120+ study sessions logged this semester; average run completes in under 40 seconds.
- Students export Markdown to Notion, so our output stays portable.
- Still shipping—latency, cost, and eval dashboards stay open while we finish the workflow.
