Draw a keyboard character in the box, then press Go!
Don't make it small or it won't work!!
And please, draw the letter the way it's supposed to be drawn... :P
It won't guess right every time, but it works alright.
The most difficult characters for it to guess are P, A, :), Q, *, and f.
Which one is hardest for you?
The thumbnail isn't updating. It's a Scratch glitch. The Scratch team is working on it.
Here are all of the characters supported: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ12
Also, there are text emojis!: :P :D :) But they don't work super well.
I'm sure there are other people who have made stuff like this, so credit to them for coming up with it first.
