What YouTubeTLDR is
YouTubeTLDR is a free, self-hosted YouTube video summarizer built around Gemini AI. Enter a YouTube video URL to generate a summary, choose any available Gemini model, and customize the instructions that guide the output format. The application also exposes the complete raw transcript. Summary history is stored locally in the browser so it can be revisited later. YouTubeTLDR runs a Rust server on your own machine, with a vanilla HTML and JavaScript interface. You provide your own Google Gemini API key, which the project says is used directly without proxies or data collection, while your data remains yours. The documented deployment is a single executable of about 0.3 MB, without a database, Tokio, or frameworks. Start it by running the executable and opening localhost:8000 in a browser. TLDR_IP, TLDR_PORT, and TLDR_WORKERS environment variables can change the server address, port, and worker count. The project supports Linux, macOS, Windows, web, and self-hosted use, and its repository identifies an MIT license. It accepts YouTube URLs only; video uploads and chapter generation are not supported. The server is optimized for personal use rather than hundreds of simultaneous users.
Who it suits
YouTubeTLDR suits individuals who want local control over YouTube summaries and are comfortable running a small self-hosted executable. It fits users who have a Gemini API key and want model choice, custom prompts, transcripts, and browser-based history.
