Grammarly is launching a clever new iPhone and iPad keyboard that includes sophisticated grammar, spelling, and punctuation coaching features. Grammarly Keyboard brings the popular writing service from the desktop to anywhere you can write on iOS.

Grammarly announced the new third-party keyboard availability in a blog post this week:

I’ve used Grammarly on Safari from the Mac and it can be a really useful coach when writing professionally.

Grammarly’s iOS keyboard looks similar to the standard keyboard which is a nice approach and adds intelligent writing features like realtime grammar checking, contextual spell checking, advanced punctuation correction, and vocabulary enhancements with a synonym finder.

The third-party keyboard also offers explanations for what mistakes you’ve made when writing so you can learn from your errors and not repeat them. Having these features accessible in any app where you can write should make iPhone and iPad an even better writing tool.

You can download Grammarly Keyboard for free from the App Store.
