Mine corrected "Kaitlin" to "Maki toon"... Spelled correctly, and I even capitalized the name. It was also at the start of a new sentence.
Autocorrect is worse in many ways, but I do like that it can be used against another word, and that it can pick up on missed spaces. I think it'll get better.
The keyboard responsiveness is another issue though. I only notice it when I type really quickly.
It's funny because mine auto corrected it the exact same way but for "Kaitlyn". Oh dear.
