Keys stay in your browser's local storage and are sent only to the official service endpoints (Google Cloud, OpenAI, Gemini, Ollama, OpenRouter, Soniox). They never pass through any third-party server. ❓ What if a video has no subtitles at all? You'll need a Soniox API key for that. The extension captures the tab's audio stream and converts speech to text on the fly. ❓ Is this useful for language learning? Very much so. The bilingual display lets you compare original and translated text line by line. Pair that with voice readout for pronunciation, and you've got a solid immersion tool using real-world content. ❓ How does the AI Summary work? On YouTube, click the ✨ Summarize button on the right side. The extension grabs the video transcript and sends it to your chosen AI provider (OpenAI, Gemini, Ollama, or OpenRouter), which returns a structured summary with overview, key points, takeaways, and details — written in your chosen language. Summaries are cached so you don't need to regenerate them. ❓ How does Local WebSocket TTS work? Select "Local WebSocket" in TTS settings and run the supertonic-tool server (github.com/thanhng8/supertonic-tool). The extension connects to your local TTS server for speech output with adjustable playback speed. • Site access (YouTube, TED, Udemy, Coursera) — to read captions and render the overlay on the player • API access (Google, OpenAI, Gemini, Ollama, OpenRouter) — to send translation/summarization requests to your chosen provider • Tab audio capture — only used when Soniox STT is active, to generate captions from audio • Storage — to keep your preferences, cached translations, summaries, and API keys locally 💬 Questions, bugs, or ideas?
