Press the green flag and try saying a sentence that contains a fruit. It doesn't support all of them, but the most common ones are included. It doesn't filter specific words, sadly, it just detects if there's a word in the blacklist.
This was destined for cloud games with chat functions. If you want to use this in your game, make sure to credit me. It should (theoretically) be fine with Scratch TOS, since there's no actual swears and none of the words from the blacklist are translated. Still, I didn't want to push my luck. Essentially, the project just uses a bunch of lists in order to translate letters into ascii code and to translate the resulting binary into base64. Since Scratch can't tell the difference between capital and lowercase letters, I had to use letters from the greek alphabet and add two more symbols. There's plenty of flaws with how I handled the detection since it's really simple (yes, despite the base64 encryption system), but it could probably be expanded upon and whatnot. shoutouts to the wikipedia page for base64 encoding frfr
