I was using Gemini, but since there was no way to categorize chat history, I created a Chrome extension.
In my case, since the chat list couldn't be managed, I kept creating chat lists with similar topics and using them,
and similar chat histories accumulated so much that it was confusing. haha
It's a simple program that creates folders by topic and manages them by dragging chat lists into the corresponding folders.

Create folders that match the topic,

Select a folder from the chat list and put it in the folder, or

You can also drag and drop from the chat list to put it directly into the desired folder.

I made it so you can search for things put in folders, and I plan to improve it.
I want to search in all chat history, but since it's dynamically loaded, there's no way to do it - -

I also made it so you can manage and use prompts, but I think this still needs some refining
