Quillbot is affordable at just $99/year, but if you just need basic grammar checking and rephrasing, it's far from the only option (or arguably even the best) in that price range.Unfortunately, it doesn't detect for Ai content currently, but it can be used to rephrase Ai generated text so it doesn't set off third party Ai detectors (as often). It can be used to check documents for plagiarism thanks to its integration with CopyLeaks. Quillbot recently surged in popularity as a tool to bypass AI and plagiarism detectors.Quillbot is great at what it does, but it isn't the same as some of the AI generating tools out there like like Frase, JasperAi, or CopyAi that focus on advertising and marketing content primarily.I recently switched to using QuillBot from Pro Writing Aid for editing my books. Thanks to their co-writer feature, it is fully capable of helping writers manage, compose, and edit full length books.
Although many people use it for very basic paraphrasing and grammar checking, Quillbot is actually a tool that can used for much larger projects.
