The #djinn story so far: I made a #lovable account and started prompting. I had a roughly working thread selection screen (the heart of what I miss about nn) within about four prompts, which burned about half of my daily free credits.
Fixing little bugs consumed the rest, but I was pretty bored of prompting by then, so I had gpt5 come up with a single prompt encapsulating what an nn-like mastodon web reader could look like.
It did a reasonable (if giant) job, so I threw that at a new #lovable project and then spent a while clicking the moral equivalent of "next" or "approve", and then a much longer while copying and pasting a progression of auth and DB errors back into the chat.
Lots of back-and-forth later, it's pulling some data and partially rendering but still broken in a variety of ways. Guessing that it has done some imperfect refactors along the way.
Bored of this at this point, going to try something else. Overall burned about 40 credits, I think, to get this point, which is about a week's worth of free credits.
