SageTube turns YouTube channels into a searchable AI knowledge base. Import a whole channel, ask in plain English, and get answers cited to the exact video timestamp - click any citation to jump to that second on YouTube. Creators can publish a public Expert their audience can ask - and even charge per question (you keep 70%). Product Hunt exclusive: sign up via the launch link for a $20 starting wallet credit + 30% off your first 3 months of any paid plan.
I'm the founder of SageTube. I built it because I kept hitting the same wall: I'd learn something genuinely useful from a YouTube video, and three months later I could not find it again, or the video is 2 hrs long and I don't have time to watch it, or there are just too many videos to watch. I just want to know what the video is about. For anyone who learns from long-form content - and especially for creators sitting on hundreds of tutorials - that's a huge amount of trapped knowledge.
SageTube fixes that. You paste a channel and it becomes a searchable, chattable knowledge base. The part I'm proudest of: every answer is cited to the exact second in the source video, so you can always click through and verify - no hand-wavy AI summaries you can't trust.
A few things that make it more than a summarizer: - Whole-channel import, not one video at a time. - Cited chat - answers link to exact timestamps; if the videos don't cover it, it tells you instead of making something up. - A Chrome extension so you can save videos without leaving YouTube. - Public Experts - creators can publish a branded page their audience can ask, and even charge per question (creators keep 70%). - Offline expert on Android app - will be published very soon (you will be able to chat in airplane mode)
You can try a live one right now, no signup: engineerguy.sagetube.ai - it's Bill Hammack's "how things work" channel turned into an askable expert (built with his Creative Commons videos, full attribution to William S. Hammack / engineerguy). Ask it how aluminum cans are made. 🙂
For Product Hunt today: sign up via sagetube.ai/producthunt and I'll bump your starting wallet credit from $5 to $20, plus 30% off your first 3 months on any paid plan. No catch, no upvote required - just wanted to give this community a real head start.
I'm here all day (I'm in Poland, so I'm actually awake for the whole US morning for once). I'd genuinely love your feedback - what's confusing, what's missing, what would make you use it. Tear it apart. 🙏

Love how clicking a citation drops you straight to the exact second on YouTube instead of just linking the whole video. That tiny UX choice makes the whole "AI knowledge base" idea actually useful instead of gimmicky.

@ogluemel68240 thank you for checking out the demo, much appreciated! This is really important to me to emphasize the actual source of the information provided by AI based on the sources we provide. This is a proof that's it's not a hallucination or training data but that's it's rooted in the data we want it to use - so it can be subjective - which is the goal of the app.

Hey Product Hunt!
