Vummary — YouTube Summary, Transcript & Chat

Summaries, transcripts, chat and highlights for YouTube — with your own AI key.

✨ Summarize YouTube videos with AI and chat about the content without leaving the page. Vummary uses the video transcript to generate timestamped summaries, answer questions, summarize comments, and save highlights in a panel integrated with YouTube. 🚀 FEATURES • AI summaries with clickable timestamps. • Chat about the video using its transcript as context. • Searchable transcripts with language selection and export to TXT, SRT and Markdown. • Summaries of comments loaded on the page, including recurring points, overall tone and disagreements. • Colored highlights and notes stored locally, with Markdown export. • Open a prepared prompt about the video in AI services such as ChatGPT, Claude and Gemini. Automatic sending is optional. • Compatible with multiple AI providers, including OpenAI, Anthropic and DeepSeek, as well as custom compatible HTTPS endpoints. • Light and dark themes, player and thumbnail shortcuts, and a double-X shortcut. 🔑 USE YOUR OWN AI KEY AI features inside the panel use your own API key and the selected provider/model. Provider charges and usage limits may apply. Transcript availability depends on the captions available for the video, and comment summaries depend on the comments loaded on the page. AI-generated answers may contain errors. 🔒 YOUR DATA No Vummary account is required. Settings, API keys, highlights and caches are stored in your browser. Chat history uses session storage. AI requests send the relevant transcript, video title and URL, prompts, chat context and your API key directly to the selected provider. Comment summaries may also send extracted comments, author names, available replies and engagement counts. The "Open in" feature copies and fills the prepared prompt into the selected AI service. The privacy policy of the selected service applies. Vummary does not operate any server that receives this data. In this version, diagnostics remain stored locally. Vummary is an independent project and is not affiliated with YouTube or any AI provider. 📧 Support: malevulobug@gmail.com
