I've been using Google Gemini, standard issue on my Pixel 8. It can be very helpful but requires good prompts and follow up questions. I start by assigning an "expert" role related to my question. I'll tell it to be a "professor of electrical engineering", an "expert speaker designer", or similar. I also instruct it to seek out authoritative sources or specific sites. Then I follow up with requests and questions to resolve inconsistencies or hallucinations. This also prompts the AI to request more info from me to narrow down the information.
I don't use it for subjective evaluations of gear. That's my role. But I'll ask it to find reviews that mention a particular quality for suggestions.
