We made an app and need feedback

Hello!
We have been developing our product for several years.

https://signum.ai/

I know that such solutions already exist, but we decided to focus on AI and ML. Previously, our product was called test4startup.com. We built our new solution based on old algorithms.

We welcome any feedback on the concept. Thank you in advance.
