What AI tools are actually useful for building apps?
I've been trying out different AI tools for coding and building small projects, but there so many options that its's hard to know what's actually worth using.
I'm mostly interested in tools that help with things like writing code, debugging, working with existing projects, or quickly getting an idea into a working app.
For those of you who use AI for development what tools have you actually stuck with, and what do you use them for? I'd especially like to hear about tools that have been genuinely useful beyond the first few experiments.
