Service to verify if the article or text is written in the native language

Hi guys.
I want to try to validate my startup.
Can you help me?

This is a service that can verify if an article or text is written in the native language or not, generated by robots or written by a human.

Is this tool useful to you and how often will you use it?

if it is useful, you get free access to this service when the beta version is made.

I'll finish the beta running for a week.

Thank you very much for the help.
