- Amazing app i have it on all my work devices it helps me format any document whether is correcting me to speak to chat GPT or to edit documents on google drive.

- Developers should really start looking into it. While Edge allows the extension, updates go to Edge's store and it becomes 2 installs. One Major flaw that grammarly don't present is - if the message contains an URL, such as a google doc link, fixing the grammar will remove the link. So anytime one has an URL, quillbot becomes unusable
- Manju Jangra
- Lovely and errors free with this tools on your routine online content writing
- Cameron Salazar (Darkerowl)
- TBH I thought I would not like this addon but I have fallen in love with how easy it makes spelling mistakes easy to edit, also adds grammar and punctuation. The one thing I do wish I could do is have it learn more about the way I write and tell it to stop adding so many (;) and the long: em dash (—). which is a tell that someone used AI to edit text or write for them. Also last issue I have seen is when you hit ignore and add text, it will go back to the ignore and ask you to edit it again, or edit it again if you do the 1 click edit all. _________________________________________________________________________ Google:Info! 1. The long dash commonly used in AI-generated text is called an em dash (—). Sometimes referred to as the "ChatGPT hyphen" due to its frequent appearance in AI outputs. 2. AI models, particularly those using greedy decoding, often overuse semicolons (;)—along with other repetitive phrasing—because they are trained to maximize the likelihood of the next token, creating dull, looping, and monotonous sentence structures. This repetitive style results from the AI choosing the safest, most statistically frequent word path rather than diverse sentence construction.

- Oliver C
- This is not a viable alternative to Languagetool, as it does not check spelling. For example, in the sentence "Dis is a setnece wtih misspleled wrods uih fuioah sdiuf vuiorpogh poagvoip aiodsfjieor ioghopghiogphgipoghadsfuiepafghgiorhiaohufpeiths", Quillbot does not detect any errors.

- i love it
- electryc03
- Love this, it protects me from the grammar Nazis. I'd give it 6 stars if the service didn't cost so much. I use the free version, but if you the next level up its pretty ridiculous. The free version suits me fine, although I use it so much I feel guilty.
- Kevin Whiteley
- The Gold Standard—Simply Outstanding This is, without question, the best app I have used to date. I’ve integrated it into both my personal and professional workflows over the last three months and have been thoroughly impressed by its flawless performance. The 'Fix All' icon is a game-changer—a unique and incredibly helpful feature that sets this app apart from every other alternative I’ve tried. I cannot recommend it highly enough; it is truly in a league of its own. I have tried a huge number of spelling and grammar apps over the years from the 1st word application (yes I'm that old) and this is by far the best one i have ever used.
