Want a free encrypted open source that can check all writings without proprietary engines of others like Grammarly, this is it. Plus, you can register to sync across devices if you choose and still free and if you really want advanced features, the full blow version, which has support across more platforms than others, is less than any other I have seen.

Mejor y más barato que grammarly, sinceramente me convencio, muy buena extension.

The best extension ever, it helps me a lot, better than grammarly and less expensive.

atomico per persone come me che fanno orrori e non errori..... ....Addio Dislessia

I can certainly tell why this is recommended.
Super clean and no need to sign up!
Love it!

Tips: disable rule like "Checks that a sentence starts with an uppercase letter" is super useful.

so good

Sehr nützlich

Tout simplement le meilleur correcteur orthographique.

Works very well and is not too intrusive.
