It says the free version only handles up to 6 lamguages, and I only wanted a simple basic spellchecker for and English blog. Installed yesterday and it just worked, pretty simply, a lot like Microsoft spellcheckers with the words underlined and click on them for suggested spelling. However that was yesterday – today it tells me I have reached the trial limits! So its not a free version, its a 1 day limited trial…

I tried a different plugin first and was shocked when it left highlighted text on my published page simply because it didn’t have British English! This plugin does understand British English and highlights unknown and misspelt words simply with a red underline. I like it!

Installed the plugin, navigated to the settings page to make sure all relevant post types were checked, and… nothing. I literally have NO idea what this plugin actually does, or how it is supposed to work. Post and page edit screen show absolutely nothing. Seems to me this is a bit of a half-baked and not very well coded plugin. No offense to the dev team, but really: if your basic version of the plugin doesn’t even work properly, it might be a good idea to leave the option of buying a premium version off the table – at least until such a time that you’ve fixed ALL relevant bugs. Not good for business selling something which is clearly broken – take some advice from a veteran plugin developer. I’ll just code my own, but for what it’s worth: WordPress 5.8.2, using Blogable theme, PHP v7.4 (ea-php74) Thanks.

I love this kind of tool, the quality of the proofreading is good. I use it in French and English.

I was not impressed with this plugin at all. The documentation was difficult to understand. The UI was difficult to use and incorporates many non-standard and counterintuitive designs. The UI, documentation, and features are all lacking. It misses some spelling errors and falsely identifies correctly spelled words as misspelled.

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.
