Universal interface for enhancing the user experience of websites with videos and audios, such as YouTube, Odysee, Coursera, etc. 👾 Features: - Playback rate adjustment for videos and audios - Volume adjustment for videos and audios - Some built-in functions of videos and audios - Danmaku service for YouTube ‼️ IMPORTANT: This project is to develop a universal playback interface in the form of a browser extension to control online video or audio playback for every website embedded with video elements, such as YouTube, Odysee, Coursera, etc. Currently, each website provides its own control interface, and the functions provided are different, which will undoubtedly lead to deviations in the ease of use of the video control interface of each website, but they should actually share a large number of common characteristics, such as playback rate, play/pause, loop, etc. Specifically, this extension is supposed to specialize in aspects of playback speed controls. Additionally, this project also attempts to provide danmaku services for video sites, currently including YouTube.

They're optional upgrades: • Google Cloud Translation → better accuracy, especially for nuanced or technical language • OpenAI / Gemini / OpenRouter → AI-powered context-aware translation + video summarization • Ollama → completely free and private, runs on your own hardware • Google Cloud TTS → premium Chirp3-HD voices that sound remarkably natural • Soniox → generates live captions from audio when a video has no existing subtitles ❓ What is Ollama and how do I use it? Ollama lets you run AI models locally on your computer — completely free and private. Install from ollama.com, pull a model (e.g. `ollama pull llama3.2`), set environment variable `OLLAMA_ORIGINS=*`, restart Ollama, and select "Ollama (Local/Cloud)" in the extension.

Google Cloud gives you 500,000 translated characters per month at no charge. OpenRouter has many free models. Ollama local is completely free. You'd only pay if you go beyond those limits or use paid models. ❓ Is my API key secure? Absolutely. 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.

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.
