I need it for my Blog in German, even if i have changed it to German in the Settings it swaps German Words with English Words. No sense in using it for my German Website then. If you cannot manage it to use it in German don't offer it.

This installs a settings panel, but no spell check tool shows up. It wasn't clear how to run a spell check on the site. I looked through the documentation which covered architecture, hardware requirements, configuration, and other confusing and seemingly irrelevant topics. In short, I was unable to use this plugin to perform a spell check on my site.

En la descripción indica que si hay idioma español de forma gratuita, pero al instalarlo me encuentro que es mentira. Desinstalado.

This is the third time I've edited this review. My first was negative, 2 stars. I wrote that it wasn't working in Gutenberg at all and was useless if I had to click in each and every block to find error suggestions. The developer responded right away and told me to give them a chance to work on that problem. They did! And now I can say with absolute surety that this is the first and only plugin at this time that grammar checks ALL Gutenberg blocks on your screen without having to click on each one. I am a paid user of Grammarly Premium, and after two years, they have not been able to make this happen. I am impressed. So, kudos to the team and the fast response to the issue. I've only used the basic, free plugin so far so don't have access to all the features yet. But I can already tell it's an excellent product and does what it does well. I wish they would make a Chrome extension as the plugin works so well in WordPress so it would be nice to have it in the browser for all sites (other blogs, social media, etc), but that's no fault of the plugin. It is a WordPress plugin, after all! But hopefully, they'll consider it in the future. Their pro version is very reasonably priced but I haven't used it yet. The free version however is excellent at checking spelling and suggesting some other minor grammar issues. It even allows you to add words to the dictionary easily. I was also impressed when I purposefully added letters to words and the plugin was able to figure out what the words were supposed to be. The support team is responsive, the plugin rocks, and I highly recommend it.

This seems to be the only spell checker with more languages available. Why isn't it updated for newer WP versions? I'd love to use and buy it, but not if it's not compatible anymore.
