Terrific spell and grammar checker. It also has the ability to save personal dictionary.

Definitely a help-mate, catching my many flubs, both minor and not. This works in a smooth and helpful manner without ever feeling intrusive. A wonderful tool to help writers express themselves with a prompt and non-intrusive alert. This enables a writer to develop each piece "live" in a smooth and effortless way. What a wonderful tool!

It no longer works with Google Docs (I get spelling error underlines but it doesn't allow me to click on them).
They also keep pushing gen AI features.

good

Una de las pocas extensiones de ortografía y gramática que permite tener las funciones localmente, sin mandar todo mi texto a un servicio externo. Además, es software libre :D

does its job well but I hate that I cannot turn off the badge that shows off "advanced writing errors" in the small dropdown because it's extremely distracting to me. I understand the purpose of it is to persuade people into getting the premium version to see what "advanced writing errors" they've made, and I quite frankly feel a bit disrespected by it.

Will record your personal info including bank info and passwords very sketchy and dangerous! Total garbage I can manage far batter than this joke of an add on. I tried it out just in case I missed something and it cost me more time trying to stop all the mistakes it made! I'd leave out a letter like say "leter" and it would give me all the choices except "LETTER"! As for so called reviews claiming the premium is great I wonder how much they were paid or do they work for the joke of a company. This is by far the worse add-on I've ever tried. It's non-stop so called mistakes aren't mistakes like " it will point it out for no reason and the user is left with a bunch of nonsense. Avoid this you'll do better on your own and will save yourself time on correcting their mistakes. As for the 5 star reviews yeah right!

Auto correct for the web

You get notified of certain errors only checked by having a premium subscription, but it won't tell you where or what the errors are and you can't disable this incredibly annoying behavior. Also, despite the fact that there's no mention of AI in the description, AI integration is all over it (and very limited for free users). Even the name of the extension in the Add-On Manager has AI in it. It's the very first word! What a weird, shady-seeming, and obnoxious extension.
And by the way, LanguageTool, your setup process has at least two typos in it. You can't even be bothered to run your own copy through the AI tools you try to push on us? You failed to inspire confidence from the very beginning and then you lived up to that impression spectacularly.

Works well. With premium, the sentence rewriting comes in handy with all the web apps used for work.
