Saving YouTube Videos with the Extension — Help

How to save YouTube videos and their transcripts using the BrainTube Chrome Extension.

The Chrome Extension makes saving YouTube videos effortless.

How to Save a Video

Navigate to any YouTube video
Click the BrainTube extension icon in your toolbar
Click "Save to BrainTube"
Wait for the confirmation — the video is now in your Library

What Gets Saved

When you save a YouTube video, BrainTube extracts:

Full transcript — The complete spoken text with timestamps
Video metadata — Title, channel, duration, publish date, thumbnail
Chapters — If the video has chapters, they're preserved
AI Summary — An automatic summary of the key points
Key Entities — People, tools, concepts mentioned in the video
Topic Tags — Auto-generated tags for categorization

Transcript Sources

BrainTube tries multiple transcript sources in order:

YouTube's official captions — Most accurate
Auto-generated captions — Available for most videos
AI transcription — Fallback for videos without captions

Tips

Videos without any transcript can still be saved, but with limited searchability
Long videos (2+ hours) are fully supported — BrainTube chunks them intelligently
Playlists — You can import entire YouTube playlists as Courses
Private/unlisted videos — Can be saved if you have access to them in your browser

Troubleshooting

"Transcript not available" — Some videos disable captions. The item will still be saved with metadata.
Extension not detecting YouTube — Make sure you're on a youtube.com/watch page, not an embed.
