Which AI do you use to help with DD or general CO info

I’ve tried Gemini, grok, chat gpt, for generally getting as much information as I can. I found it helpful because it mentions things and other links to help you investigate further.

I found Gemini to be good for general stuff. Grok was better for investing information as well as ChatGPT.

Just wondering if anyone knows of or uses investing AI chats or something more specific? New to all of this so looking for guidance thanks.
