This one uses Chrome's built-in AI (Gemini Nano), so it's genuinely free, unlimited and private: the transcript is read from YouTube's own transcript panel, the model runs on your machine, and nothing is transmitted anywhere. REQUIREMENTS, HONESTLY Chrome 138 or newer, and roughly 22 GB of free disk for the one-time model download (Chrome handles it; the extension shows progress). If your device can't run the model, the extension says so and offers the transcript to copy instead. Videos need captions.
