One-click YouTube transcripts and on-device AI summaries, with session history and detail pages Copy YouTube transcripts or quickly generate AI-powered summaries directly from thumbnails without opening the video. Hover over a thumbnail, click the button, and instantly paste the transcript or summary from your clipboard. ThumbSkript works on the YouTube homepage, search results, channel pages, Shorts, and the inline preview player. HOW IT WORKS • Hover: 📋 Transcript and ✨ AI Summary buttons appear on thumbnails and in the preview player. • Click: ThumbSkript retrieves the available captions and can optionally generate a local summary in the background. • Paste: The result is copied to your clipboard with a compact header containing the video title, channel, duration, and URL. KEY FEATURES • One-click transcripts: Automatically copies the most appropriate caption track, with optional timestamps in [MM:SS] format. • Local AI summaries: When Chrome’s Prompt API is available on your device, Gemini Nano generates concise 5–8 bullet-point summaries locally, with no API keys or third-party servers. • Session history: Access your recent transcripts and summaries from the extension popup during the current browsing session. • Seamless experience: Repeated requests use cached results, button visibility is configurable, and no account or sign-in is required. PRIVACY AND LIMITATIONS • Local processing: Summaries are generated directly on your device when Chrome’s Prompt API is available. Your content is not sent to an external AI service. • YouTube captions: Transcripts are retrieved from YouTube. Videos without captions and some live streams are not supported. • Session storage: Generated transcripts and summaries are stored only during the active browsing session. They are deleted when the browser is closed or the extension is reloaded. • Preferences: Settings such as button visibility, timestamp display, and AI activation are saved in your browser and may be synchronized with your Chrome account.
