Edit: So, where do I start? The idea is good. The beginning was just great. It gave me a lot of hope. Unfortunately, then there was the barrier with the 50 files.
So I waited for an improvement. It came... for exactly three more runs. Then silence. Greta is just doing nonsense now to my project. That was three weeks ago.
I can't see any improvement even in beta. In response to my feedback on the beta version, I only received a superficial text block suggesting that the problem was my prompt.
After my initial enthusiasm—the first attempts were really great!—I have now reached a point of disillusionment and disappointment. Greta breaks more than it fixes.

My rating after a little more than 60 days:
Support: 0/5
Performance: 2/5

Since support is an individual service (yes, @shubham, you're already in the loop!) and I still have some hope left, there are two points left.

Old: This is definitely one of, if not the best, purchase here on Appsumo. The application not only has potential, but it's also really fun to work with. It actually produces really good, usable stuff. Unfortunately, that's not the case with all deals here. Good work!
