Ratings and reviews

The app is amazing. It's pretty cool to use the keyboard as well; however, the keyboard could use some updates, like having the ability to remove a learned word and have the word actually go away. Additionally, the keyboard can obstruct the view in some apps, preventing you from seeing what you are typing. One positive is having the ability to generate a better sentence. After a long day, when your brain is tired, you just type in your idea, and it corrects and gives options.

Though I'm a premium member, QuillBot has been extremely disappointing, especially its AI detector feature. It often flags content I’ve written entirely on my own as 80–90% AI-generated, which is completely inaccurate. At the same time, when I tested it with actual AI-generated text, it reported only around 20% AI. This inconsistency makes the tool unreliable and defeats its purpose. An AI detector should provide dependable results, but in this case, it feels misleading rather than helpful.

The worst app one can use for AI detection. Quillbot will pull a random number out of thin air and give your document that score. Requested for a refund 30 mins after using the app and finding it trash, only to be rejected as they don't entertain refunds from regions that don't enforce refund by law.
