Thank you for bringing this to my attention! You were completely right: ChatGPT changed their underlying website code a while back, which unfortunately broke the extension's ability to detect when it was typing. I've just released a major update (v0.1.2) that completely fixes this issue and restores full functionality for ChatGPT. It also adds brand new support for Google Gemini and Claude! If you have a chance to try it out again, I'd really appreciate it if you could update your review. If you run into any other issues, please feel free to reach out at addons@smolkin.org!
