Tube-U is an AI YouTube research tool. Describe what you want to learn, and it finds the best videos on the topic, reads their full transcripts, and synthesizes everything into one clear research report — organized by theme, with inline timestamp citations back to each source. It is not another single-video summarizer: it combines many videos into one answer, the way a human researcher would.
Most tools summarize one video at a time. Tube-U synthesizes multiple sources into one research report — cross-referencing claims, surfacing where sources disagree, and citing every point back to a specific video and timestamp. There is also a free Video Triage mode that ranks videos by substance, evidence, originality, and title honesty so you know what is worth watching before you commit.
Start free with 50 credits at signup (about 5 research reports), no credit card. Then subscribe from $6.99/mo, or buy one-time credit packs that never expire.

Yes. Paste several YouTube URLs or describe a topic, and Tube-U reads every transcript together and produces one unified report — cross-referenced, deduplicated, organized by theme, with timestamp citations — instead of a separate summary per video.
Single-video summarizers produce one summary per video, even in batch mode. Tube-U synthesizes all selected videos into one research report: it identifies consensus, flags where creators disagree, and cites every claim back to a specific video and timestamp.
New accounts get 50 free credits (about 5 research reports) with no credit card. Video Triage is free for up to 50 video rankings per day. You can also preview a real report on your own topic once a day without signing up at all. Paid options start at a $4.99 one-time credit pack (credits never expire) or a $6.99/month subscription.
Yes. Type a topic on the homepage and Tube-U runs a real research pass in front of you — finding videos, reading their transcripts, and streaming the report as it is written, with timestamp citations. The opening findings are free to read, one preview per day, no account needed. Signing in unlocks the rest of that same report using your free signup credits.
Yes. Video Triage reads each video's full transcript and ranks the batch into Must Watch, Worth It, or Skip based on substance, evidence, originality, and title honesty — adapted to whether you want deep learning, a quick overview, multiple perspectives, or current events.
Reports can be generated in 16 languages, and source videos can be in any language that has captions available on YouTube.
Yes. Every report and single-video summary has an AI chat. Ask follow-up questions and the answers cite the source videos with timestamps. Your first 25 questions each day are free, then 1 credit per question; you can optionally have an answer fact-checked against the live web for 3 credits.
Yes. Save a Digest — a named list of channels, with an optional focus topic — and Tube-U pulls each channel's latest uploads and synthesizes them into one briefing whenever you ask. Digests can be shared via public links.
Yes. News brief mode builds a developing-story briefing from the freshest coverage: pick a recency window (down to the last few hours) and the brief separates confirmed facts from single-source claims, flags where newer videos contradict earlier ones, and is stamped with when it was generated.
