Turbo AI (formerly TurboLearn AI) turns recordings and PDFs into notes and flashcards. BibiGPT does the same for 30+ video sources — paste a YouTube or Bilibili link and get chaptered notes, a mind map and flashcards in one pass.
Turbo AI (rebranded from TurboLearn AI) is popular with students who record live classes on their phone. If most of what you study is already online — MIT OCW, CS50, Coursera previews, Bilibili course uploads, long podcasts — you can skip the download step entirely.
BibiGPT reads the video link, pulls the subtitles (or transcribes the audio when there are none), and returns chapter summaries, a mind map, AI follow-up chat and flashcards. Long 2–3 hour lectures are supported, and notes export to Markdown, Notion or Obsidian.
Keep the note-taking speed, add every video platform and timestamped review.
YouTube, Bilibili, podcasts, Douyin, TikTok and 30+ sources work straight from the URL.
