How have you been using AI to help with Stock fundamental research (ChatGPT, Gemini, Grok etc.)

Hey guys, just wanna know if any of you here use large language models like ChatGPT, Grok, Gemini or DeepSeek for screening stocks or getting more precise fundamental data about a company faster?

I wanna know if you guys had any significant advantage doing this and whether it helped your portfolio perform better. Does using these chatbots help to gain a deeper insight into the future prospects of a company, perhaps allowing you to think in different perspectives than you otherwise would, because of the information that these apps provide. I know they can’t predict the stock price or whatever, but I wanna if it has made your research faster and easier, and whether that had any impact on your portfolio’s performance.

I personally have been using AI a lot for fundamental research, but they aren’t very good at sentiment analysis yet, and aren’t very good at stock screening either.

How do you guys think this technology can impact your portfolio decisions, and have any of you tried to fine tune open source AI models on your own datasets? Has that given you any sort of edge in the market?
