Random keyword question: Capitalization

Hello Manychat folk!

I’m new to the Manychat platform and have a newbie question. 

For the “keyword” feature, how does Manychat treat capitalization? For example, if my keyword is “network” will it trigger the automation if people comment or reply with every possible instance of capitalization of the word (for example “Network” and “NETWORK”) or do I have to continue putting in every possible capitalization option as a keyword?

Thanks for your help!
