Whichever one you're using is probably borrowing massively from iNaturalist that also has (and has had for a long time now) its own AI-powered identifier (which recently underwent a major update).

iNaturalist is a platform to allow citizen scientists to upload observations of any species. The distribution data is what's most used in published research and databases like GBIF, but photos can also be uploaded with any license the observer wishes and iNatualist has decent APIs and works hard to make its data accessible to anyone

PlantNet and BirdNet are two of my favourite apps ever. They feel like a proper realisation of the power of smartphone technology (as opposed to all the other crap)
