@alinanorakari I tried to use it to get a hint on a regex I got stuck with. It gave me 4 correctly looking wrong answers I had to refuse, then a correct one, but not working in subset of regex used in sed, and when repeatedly told that it doesn't work in sed, it got into a loop of "Oh, I'm sorry, you are correct, this won't work. The correct regex is: repeats the same regex
To be fair, at the end, it got unstuck and even provided explanation for why isn't it working, but yea... Whoever uses it for something they don't already know enough to verify the result is setting themselves up for a failure.
