最初它工作得很好,但是後來失效了,前後的Prompt,Study Goal都沒有改變。我猜可能是因為調用的模型的問題。希望增加通過自己的大模型api來判斷的選項。 Initially it worked very well, but later it stopped working, and the Prompt and Study Goal before and after did not change. I guess it might be because of the model being called. I hope to add an option to make judgments through my own API.

Tried it, and it's great for keeping you away from distractions. Love the extreme customizability which allows you to focus on the thing you're working on now (whatever it may be) -- by providing an allow / ban list, but also being able to provide a general description of what you want to get done.

The extension is light-weighted, extreme smooth and highly customizable. Really good for me to prevent myself scrolling instagram lol
