Notebida - An AI tool that drafts study notes from lectures & PDFs

by
Notebida is an academic/research demo exploring how AI can help with studying. Give it a lecture video (YouTube/Bilibili/upload) or a PDF and it drafts structured, bilingual (中/EN) notes shown next to the source — click a line to jump to that moment or page. The same notes power a few study tools: • AI Q&A over your notes • Auto-graded quizzes (can follow a sample exam's format) • One-page cheat sheets • Sharing & collaboration with classmates Free to try.

Hi all — Notebida is a research/demo project I've been building to see how far AI can go in helping with studying, so I'm sharing it for honest feedback rather than as a finished product. What it does: you give it a lecture video or a PDF and it drafts structured, bilingual notes synced to the source (click a line to jump to that point). The same notes also feed AI Q&A, auto-graded quizzes, and one-page cheat sheets. It's free to try. Since everything is AI-generated it can get things wrong, so please treat the output as a study aid rather than authoritative. I'd genuinely appreciate criticism — where does it fall short, and what would make it actually useful for you?
