Well, I tried extracting fields from some logs I had lying around and I can tell you why I think it's not useful: 1. I select DEBUG and INFO, but it doesn't work out that there are WARNs etc in there and extract those too.

2. Some of the regexes are just.. wrong? I selected individual fields but there's one mangled regex that gives me two fields and the text in between, I didn't ask for that and it's no use.

3. None of the regexes could extract the date I selected (of the form 2023-03-28 05:23:28.844); some of the 'agents' used the literal date, the only one that broken it down into \d's didn't match anything because the DEBUG and INFO were mangled into there.

I'm not really sure how this would be at all useful in its current form?

Well, I know nothing about AI and tried with simple variations of "foo bar baz."

The only solutions that worked were either "\w+ \w+ \w+..." which does not filter anything and may produce errors with other content, or "(first line|second line|third line)" which could be replaced by a bunch of if statements.

The other solutions were plainly wrong but at least they are honest about it and it's shown in the user interface.

For me it's more than useless and I get faster results with https://regex101.com/.

How do I tell it to generate a regex for emails? Try selecting the emails. all four generated Regexes are wrong. Even if one of them was right? how do I choose between 4 choices if I Don't know the meaning? I have to verify the generated Regexes, Veryfing complicated regexes is much harder than writing them in first place.
