This is nice! I do use ChatGPT a fair amount as I’m still crap at Latin and Greek, but a lot of scholarship just plonks it in untranslated. It has always worked fine for getting the gist. I am extremely lucky in that while moving house my wife allowed me to buy the complete Loeb collection but until then I spent a lot of time on Tufts’ Perseus library. The Latin and English sources (and Greek for that matter) are all in XML on GitHub, so some enterprising soul could probably hook up a wider set of books from here:
Perseus seems to be slowly falling apart; I think it's unmaintained. I also think there's supposed to be a more current replacement. But that's as far as my knowledge goes; do you know more?
It does seem under resourced. Version 5 never appeared and I don’t know what 6 is supposed to look like. It’s still a great online resource, but having my own library, and access to the Hellenic and Roman Library in London, I’m happy to take things slow these days.
