Description
A service that allows you to use three AI LLMs (Gemini, ChatzyPT, and Claude) simultaneously.
1. All conversations are saved solely in the Chrome browser, not through the server.
2. English translation and prompts have been added to the basic conversations for more precise conversations. *Ctrl+Enter for general conversations.
3. Summarize the conclusion in the first sentence for quick information comparison.
4. You can use your own account to access your paid LLM accounts. *For non-subscribed accounts, only the free quota is used.
5. Using your own account, you can use all the features of each LLM.
6. You can have separate conversations for each LLM you've set.
7. You can also add other sites using custom slots. *Some sites may be blocked.
8. If you log in at the bottom, the slot order and customization settings are remembered.
9. You can drag to translate.

10. Clicking the logo hides the main chat window, allowing only the split window function.
