Current A.I. is all over the place. It’s hard which ones to recommend as they evolve and names change. Google(Gemini\Bard) and Microsoft (Copilot) are quite large – server farm-wise. OpenAI is made in many apps. DeepSeek is in the news lately. There was once a philosophy bot I liked that actually remembered my answer\correction a year and a half later. Do any of these share search results with each other? No clue.

Modern solution… treat it like a search engine… best to use more than one, just make sure.
