MergeKey

The keyboard that only shows the letters you need. 20 languages, smarter prediction, Liquid Glass design. Type faster, make fewer mistakes.

MergeKey — the first keyboard that hides the keys you don't need.

As you type, MergeKey dynamically removes impossible letters and expands the remaining keys, giving you bigger tap targets and fewer typos. It's like autocomplete, but visual — you see your options shrink in real time.

MERGE MODE — UNIQUE TO MERGEKEY

• Keys that can't continue your word disappear instantly
• Remaining keys grow to fill the space — bigger keys, fewer mistakes
• Learns new words you teach it
• Toggle Merge Mode off if you prefer just the disappearing keys without resizing
