K'ai
Korean, written right. Replies in one line.
It fixes only the line you tap. Not right? One backspace.
Concept
There are plenty of keyboards that fix English. Few fix Korean well.
K'ai tries to be the best at one thing: Korean spelling, spacing and tone.
One button while you type, and the corrected line drops into place.
What it tests
How far do people trust text an AI has rewritten?
We count how often an edit is undone with one backspace. The target is under 15%; tones and lengths that get undone most are what we fix next.
Only when you tap
A keyboard sees everything you write, so we cut what leaves the phone to the minimum.
Typing stays on the phone; only the line you tap is sent. The server keeps no text, only counts.
Who it's for
Anyone who worries about the tone of every work message.
Anyone who freezes at the send button over Korean spacing.
Anyone who closes the chat because they cannot find the first line of a reply.
