Code snippets are fine, but I'd actually rather just use ChatGPT to generate code snippets and ideas, and have it explain to me details and other options in a conversational way.
Thus in general this approach, like most other AI search options, doesn't excite me.
At a high level, I think AI search is terribly hard to solve. You're fighting against existing user patterns heavily tuned to the nuanced behaviours of existing search. So you have to find a specific use case that Google sucks at (and while StackOverflow's fall from grace somewhat lends an opportunity, I think it's not sufficient for most developers to start looking for a different solution) and that you're 10x better at.
But 10x better means your speed has to be just as fast, your answers have to be significantly better, and crucially you have to be nearly 100% consistent, which is brutally hard for most AI approaches.
At that point I wouldn't even market yourself as search. In this context maybe something like "AI-powered software development assistant".
