Great

einfach und unkompliziert, bestens das Tool, - Danke

Всё быстро,удобно и понятно.

Pretty impressive tool with accurate corrections. Used Grammarly for a while but open to try new add on's too. So far, i'm impressed.

Love this extension! So easy to use and isn't heavy on your browser.

Круто

This young extension is an open and secure alternative to proprietary solutions such as Grammarly.

Main Feature: unlike competitors, it does not send anything to remote server unless user explicitly asks it to do so.
Ability to opt-in for automatic checks ONLY for specific websites is a very useful feature and a good design.

Keep up great work!

Continuate così!

Great tool for those who want to write the correct way.

And better yet, is open source.

Ugly icon tho.

Great news!!! But somehow it is labeled as "Legacy" in my Add-ons list.

Nice, free, and very useful for non-native english people.
