How do i connect my grammar checker website with my dictionary in python

I have built a grammar checker in python, and it works well in the terminal, but i don't know how to implement it on the web. How can i implement a grammarchecker on the web like Grammarly? I did not find article that that talked about that at all. Please help guys. I will not need a database because I have a text file for replacing words. What i don't know is, if i will need some sought of a server to communicate back and forth for reading, checking, and retrieving. The link on the grammarchecker button should also be protected to prevent people from using my code to do their grammar checking functionalities on their websites. Please help on these issues guys. Help make the world a better place.
