"并不是摘要，而是回声。" "Not a summary, but an echo."
Echo is a Chrome Extension that brings a "soul" to YouTube videos. Instead of dry AI summaries, it summons a specific persona (based on the video content) to offer profound, first-person insights and engage in a dialogue with you.
- Ω Button: A subtle, breathing Omega button appears next to the video title.
- Soul Channeling: Automatically analyzes the video content and summons the most suitable expert or thinker (e.g., Socrates, Steve Jobs, Feynman) to comment.
- Identity Awareness: Intelligently identifies speakers and ensures the commentator is a different perspective, not just an echo of the speaker.
- Deep Dialogue: Chat with the summoned persona. They will respond in character, using first-person perspective ("I believe..."), and can reference specific parts of the video transcript.
- Aesthetic UI: A premium, dark-themed design with cinematic animations and golden amber accents.
Since Echo is currently in Beta and not yet on the Chrome Web Store, you can install it manually:
- Download Code: Click the green Code button above and select Download ZIP, then unzip it.
- Open Extensions: Go to
chrome://extensions/in Chrome. - Developer Mode: Toggle on Developer mode in the top right corner.
- Load Unpacked: Click Load unpacked (top left) and select the
echo-v2folder. - Enjoy: Open any YouTube video, look for the Ω button near the title, and click it!
The backend of Echo uses a Cloudflare Worker to securely proxy requests to the AI model (Aliyun Qwen).
