About
Save once. Query anywhere. BrainTube is your YouTube library, in the AI tools you already use: save the videos and articles you care about, then search them, chat with them and remember them.
CAPTURE FROM ANYWHERE
Tap Share in YouTube, Safari, Voice Memos or any app and send it to BrainTube. Video links, web pages, PDFs, screenshots and voice memos are transcribed, summarised and filed into your library automatically.
FIND ANYTHING
Search your whole library by meaning, not just keywords. Ask for "that talk about sleep and memory" and BrainTube finds it.
CHAT WITH YOUR KNOWLEDGE
Ask Cue questions and get answers grounded in what you saved, with links back to the exact sources.
REMEMBER WHAT YOU LEARN
Spaced-repetition recall turns your saves into short review sessions, scheduled so ideas stick instead of fading. Streaks, daily challenges and a 60-second quiz keep it fun.
ONE BRAIN, EVERY DEVICE
Your BrainTube account syncs with the web app at brain-tube.com, so everything you capture on your phone is there on your desktop too.
PLANS
BrainTube is free to use with 30 credits a month plus credits you earn. Starter and Pro add more monthly credits, faster earning and bulk imports. They are auto-renewing subscriptions, billed monthly or yearly through your Apple ID, with a 14-day free trial for new subscribers. Payment is charged to your Apple ID at confirmation of purchase. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel any time in your Apple ID settings.
