Noiz

Noiz is a summaries tool that turns any YouTube video into an instant, timestamped AI summary with one click.

Noiz is a browser extension and mobile app that generates AI-written summaries of YouTube videos so users can grasp the key points without watching the full runtime. Rather than requiring a prompt or a separate app, it adds a button directly to the YouTube video page: clicking it produces a digest of the video's main ideas, formatted as either a bulleted list or a question-and-answer breakdown, in brief or detailed form. Summaries are timestamped, letting a reader jump straight to the section of the video that matters to them, and the tool can also convert a video's spoken content into a readable transcript. The tool is aimed at people who consume a high volume of video content for work or study — students digesting lecture-style videos, researchers scanning long interviews or panel discussions, professionals keeping up with industry talks, and content creators mining existing videos for ideas to repurpose. Because it works across 41 languages and can translate generated summaries into more than 40 languages, it's also positioned for a non-English-speaking or multilingual audience rather than English-only content. In practice, the workflow is: install the browser extension (or the iOS/Android app for mobile use), open any YouTube video — public or unlisted, including podcasts hosted on the platform — and click the Noiz button to get a summary in seconds. The stated ceiling is videos up to 12 hours long, which covers everything from short clips to full multi-hour courses or podcast episodes. A companion feature tracks a weekly top-100 list of videos, intended to help users spot emerging topics without manually browsing YouTube's own trending pages. Within the broader video-summarization category, Noiz's differentiators are its direct one-click integration into the YouTube interface (no copy-pasting URLs into a separate site), its language coverage, and the option to view output as key ideas, Q&A, or full transcript rather than a single fixed summary format. It competes most directly with other YouTube-focused AI summarizer extensions rather than general-purpose text summarization tools, and its value is concentrated specifically around video content rather than documents, articles, or arbitrary web pages.
