Which dev docs? I guess you could provide it with links and ask questions, but I tried that with a transcript of a Japanese class I missed and it was very very wrong with the page numbers and asking it about homework (and those parts were in English which it should support). For LN spec stuff I’d think it’s mostly useless because you need the details. Maybe asking where things are and then go refer to the actual spec, but don’t be surprised if it is confidently wrong like ChatGPT etc.
