Unsaid – AI YouTube Summary & What's Sourced by Zelo

A YouTube video summary, and what backs it up.

Unsaid summarizes a YouTube video in one click, right next to the player: its thesis, key takeaways and a timestamped summary. Then it shows what the video claims, what is sourced and what is not, and the interests at stake. Useful for lessons, product reviews, and finance, health or coaching videos.

WHAT YOU GET
• The gist: a one-line summary, key takeaways and a timestamped summary of the video.
• The outline: the video's chapters, each summarized, with markers on the progress bar.
• Claims: every central claim, timestamped (click and the video jumps there), with a status — sourced, unsourced or disputed — what is missing to establish it, and the strongest counter-argument.
• Check on the web (Pro): a claim looked up in original sources (studies, public agencies), with their links.
• Interests at stake: disclosed sponsor, affiliate links, promo codes, the creator's own products, partnerships mentioned out loud.
• Comments: up to 500 comments and replies read, summarized into trends, with exact quotes.
• Persuasion techniques, with the exact sentence from the video.
• While watching: markers on the progress bar, and a note when the video reaches an unsourced claim.
• No captions: Unsaid can transcribe the audio while you watch.
• History, topic folders and side-by-side comparison of several videos on the same question.
• Share the analysis: a public page, readable without the extension.
