Udemy Study Assistant is now Vidlore: Course Notes & AI Tutor. Same extension, same local-first library, now with a full study workspace and an AI tutor grounded in your course.
Study Center (Pro)
- Full-page study workspace. Open any lecture in its own tab with a collapsible curriculum sidebar and next/previous lecture navigation.
- Lecture chat. Ask questions about a lecture and get streaming answers grounded in its transcript, not a generic chatbot.
- Quizzes. Generate active-recall quizzes from a lecture. Sessions and results are saved so you can come back to them.
- Summary history. Every summary is kept. Switch between versions or delete the ones you do not need.
- Diagrams and tables. AI answers now render Mermaid diagrams and Markdown tables.
- Output language. Choose the language for summaries, quizzes, and chat, independent of the course language.
Library and Search
- Semantic search (Pro). Search by meaning, not just keywords. Embeddings are computed on your device, so your queries stay private.
- Transcript viewer. Read extracted transcripts in History with lecture navigation.
- Smarter extraction. Missing curriculum is fetched automatically, interrupted extractions resume, and you get a clear warning when a lecture falls back to a different caption language.
AI Access and Plans
- Cloud AI included with Pro. Lifetime Pro now unlocks the Study Center’s AI features with a single sign-in, including a daily and weekly base AI quota.
- AI Plus. An optional monthly add-on for Lifetime Pro users: 600,000 tokens and 600 requests per paid month.
- Quota top-ups. Buy extra AI credits that never expire.
- Usage at a glance. See your remaining quota, AI Plus period, and credits in the extension.
Interface
- Available in English, Vietnamese, Spanish, and French.
- Confirmation dialogs before deleting courses or history.
