The de facto for Western plant species ID is Pl@ntNet/iNaturalist (free and citizen scientists will ID if there is uncertainty). Then you just look up care instructions? I would absolutely not trust ChatGPT.

I say Western as the training data is skewed by common species and usually they’re a bit geographically limited (for example BirdNET works best if you use a localised model).

Also if you use these free services, you can contribute natural training data which is valuable - even for well represented species.
