Smart Keys

As an AI grammar checker, Smart Keys takes an unusual route: it lives in the keyboard rather than in a separate writing app.

Smart Keys is an AI keyboard for iPhone and Mac that checks grammar, translates text and adjusts the tone of your writing wherever you type.

It also proofreads and summarizes, so one install covers several small writing jobs.

The practical gain is that you do not copy text into another tool to fix it.

Suggestions appear where the writing already is, which makes the keyboard easy to fit into whatever workflow you have.

It runs on iOS and macOS.

AI suggestions can be inaccurate, so read them before sending anything important.

Some people also find the keyboard laggy at times, and that matters when you type on it all day.

If you write across languages or change tone often, the convenience may outweigh those flaws.
