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.
