I have an AI tool Idea , need suggestions!

Hi ! So i had worked as a freelance writer and most of my clients were YTs. I created YouTube scripts for them on various topics in Hindi. There are many such in India looking for YT scripts in regional languages.

So i wanna know if i can build a YT script writing simple tool with CHAT GPT that will provide creative scripts as per the user's inputs and in everyday Hindi (or any other Indian Language) not in BOOKIESH language. Because typical Hindi is different from what we actually speak in day-to-day life !
Maybe it can use some inputs of other channels to copy their style of the script to write a script in the same tone!

I have some networks that i think i can use to get initial users and later on i can also provide additional services (like editing and all) !

Talking about competitors then there are not any noticeable ones providing such content in regional langs and they are Expensive too ! And even if there are competitors ... I still want to give it a try !

How does this idea sound? Please share your suggestions and a rough roadmap or steps so I can know how do I go with it (the technical part especially).
