YouTube Agent - Transcript Fetch & Term Explainer

YouTube Agent is a tool that helps you understand YouTube videos by providing short explanations of technical or financial terms.

Features & Capabilities

YouTube Agent is a learning companion for YouTube. While you watch any video, it reads the transcript, finds the technical or financial terms being discussed, and shows short definitions in a floating panel — so you never have to pause, open a new tab, or lose your place to look something up.

HOW IT WORKS

When you open a YouTube video, the extension automatically fetches the transcript, scans it for recognised terms (such as CapEx, EBITDA, API, Kubernetes, Free Cash Flow), and displays definitions in a small side panel. Each definition includes clickable timestamps so you can jump directly to every moment in the video where that term is mentioned.

KEY FEATURES

• Automatic term detection — no manual highlighting needed; the panel updates as soon as the transcript loads.

• Clickable timestamps — click any time marker next to a term to jump straight to that moment in the video.

• Draggable floating panel — reposition the panel anywhere on screen; collapse it to a slim header bar when you want it out of the way.

• Download the transcript — save the video transcript as SRT, VTT, plain text, or JSON with a single click. Perfect for note-taking, AI tools, accessibility, or video editing.

• Download format settings — choose your preferred transcript format once in the Settings page; your choice is remembered across sessions.

• Suggest missing terms — spotted a term that should have a definition? Submit it with one click straight from the panel.

• Refresh on demand — transcript or term list not loading? Hit the refresh button to re-fetch without reloading the page.

• Works without a backend — a bundled glossary covers common finance and tech terms out of the box, with no account required.

PERFECT FOR • Students watching lectures or technical tutorials • Investors and analysts watching earnings calls or financial commentary • Developers watching conference talks or architecture walkthroughs • Anyone learning a new field through YouTube

PRIVACY YouTube Agent does not collect, transmit, or sell any personal data. The extension reads publicly available YouTube transcripts in your browser to perform local term matching. No browsing history, watch history, or personal information ever leaves your device. An optional remote glossary feature (disabled by default) sends the video transcript to a server you configure; it is never enabled without explicit setup.

PERMISSIONS USED • Storage — to remember your collapsed/open panel state and your preferred download format. • Access to youtube.com — to read transcripts from the YouTube page you are already on.
