My experience with AI is it sucks and never gives the right answer, so no, good ol’ regular web search for me.
When half your searches only gives you like 2-3 pages of result on Google, AI doesn’t have nearly enough training material to be any good.
The reverse is also sometimes true and it’s when a rewrite is justifyable.
I’ve worked with many systems that piled up a ton of edge cases handling for things that are no longer possible, it makes the code way harder to follow than it should.
I’ve had successful rewrites that used 10x+ less the amount of code, for more features and significantly more reliable. And completely eliminated many of the edge cases by design.
