Vendor demo looked slick. Explain COBOL, refactor, maybe COBOL-to-Java. Management is excited.

Has anyone used it on a real program bigger than a sample? Especially curious if the Java output is something you would actually maintain or if it is more of a documentation aid.

Tried explain and business-rule extraction on a 8k-line billing module. Helpful for onboarding. COBOL-to-Java on the same module needed a lot of cleanup - it worked but still "thought" like COBOL.

We are treating it as an understanding tool first, not an auto-migrate button.

Same experience. Explanation saves time. Blind transform into prod Java is a fantasy for anything that moves money.

I use the chat for "what does this paragraph do" when the comments lie. That alone is worth the seat for juniors.
