YouTube AI summaries, comments & controls in one panel

SpaceTube adds a panel right inside YouTube. Get AI summaries of the video and its comments in your language, search a click-to-seek transcript, loop any section, control speed and volume, save timestamped notes, and organize videos into folders — without ever leaving the watch page. Free to start; the Pro plan is free for a limited time, no card needed.






The transcript search that lets you jump straight to the moment someone says a word is such a smart move, makes rewatching dense videos actually bearable.

Thanks! That's the part I use a lot myself. On a long video, I search the transcript and jump to the section I need, like the design part of a headphone review. Summarizing before watching helps too, you know what the whole video covers first. That's my workflow: summarize first, then search.

Hey Product Hunt! 👋
I built SpaceTube because I watch a lot of podcasts, tutorials, and lectures on YouTube. But I'd watch a 40-minute video and forget most of it by the next day — and when I wanted to go back to that one moment, I couldn't find it.
So SpaceTube is a full panel that lives next to the player: AI summaries of the video and its comments (in your language), a transcript where clicking any line jumps to that moment, an A-B loop, playback speed and volume controls, timestamped notes, and folders for the videos worth keeping. It matches YouTube's light/dark theme and stays out of your way until you need it.
My favorite way to use it: when a 1.5-hour podcast loads, I summarize it before settling in. You know what it covers and where it's going, so you watch with more focus — the summary isn't a replacement for the video, it's a map.
It's free to try, and the Pro plan is free for a limited time — no credit card.
I'm a solo developer and this is v0.2, so I'd genuinely love to hear what feels missing. What would make this your default way to watch YouTube?
