Stop wrestling with AI to get the output you need. You write an instruction, the chatbot misinterprets it, and you waste ten minutes iterating. SecondBrain is a transparent prompt optimizer built specifically for everyday AI users. We clarify your intent, tighten your wording, and show you exactly what changed. Once you secure the perfect result, you can instantly build a library of repeatable requests.

Try it with the next prompt you were about to rewrite manually.

SecondBrain is a Chrome extension that functions as a transparent prompt optimizer.

The app functions well, but the user experience would be greatly improved by adding an option to hide or disable the persistent floating icon in the bottom-right corner. It currently feels a bit intrusive since there is no way to remove it from the interface.

Works well but the developer needs to add an option to remove the floating icon on the bottom right of every page. It's annoying and can't be removed. Also add an option to remove the Google search bar. It's unnecessary & redundant since I can just search google in my normal browser. I'm only interested in the Gemini prompt-bar.

버그때문에 쓸수가 없네요. 사이드바에서 사용할 때, 전송 버튼이 활성화되지 않습니다. 그리고 플로팅 버튼 on/off 있으면 좋을 것 같아요.
