Transtube

Read, chat with and summarize any YouTube video from its transcript, right beside the player.

Transtube adds a smart panel right beside the YouTube player so you can read, search, question and summarize any video from its transcript — without leaving the page. WHAT YOU GET • Key insights – the main takeaways of the video as a short list, each with a clickable timestamp. • Transcript – the full transcript grouped into readable paragraphs (split at sentence ends and speaker changes). Click any timestamp to jump to that moment in the video, or copy the whole transcript in one click. • Chat – ask questions about the video and get answers grounded in what was actually said, with [mm:ss] citations you can click to seek. • Summary – a structured summary of the video, in the language you choose. BRING YOUR OWN AI Transtube has no servers and no subscription. Connect the AI service you already use with your own account or API key. It works with the major AI providers, and with any OpenAI-compatible endpoint, including models running locally on your computer. MAKE IT YOURS • Edit the key-insights instructions and the summary structure to match how you like to read. • Create your own chat shortcuts and reuse saved prompts with / commands. • Pick the transcript and summary language, including YouTube's translated captions. PRIVACY • No Transtube backend, no analytics, no tracking. • Your API keys and settings are stored only in your browser and are never exposed to the YouTube page. • A video's transcript is sent only to the AI provider you choose, and only when you ask for a summary, insights or a chat answer. HOW TO USE 1. Install Transtube and open its options page to connect an AI provider. 2. Open any YouTube video (youtube.com/watch). 3. Use the Key insights, Transcript, Chat and Summary tabs above the suggested videos. Works on videos that have captions (including auto-generated ones). Transtube is an independent project and is not affiliated with or endorsed by YouTube or any AI provider.
