It offers multiple modes like Standard, Fluency, and Creative, allowing users to choose the level of rewriting they need. We found it particularly useful for avoiding plagiarism and improving sentence structure. Grammar Checker: The grammar checker is robust, catching errors that many basic spell checkers miss.

Value for Money	8.5 While Grammarly offers a free version, the Premium plan is relatively expensive. However, the advanced features and comprehensive feedback justify the cost for those who need a robust writing assistant. Grammarly is the priciest option for a reason—because, in our view, it's the best writing tool available in its category. If you're looking for the best writing assistant, go for the Premium plan, you won't regret it!	9.0 Free vs. Paid: While the free version offers basic functionality, the premium plans unlock a wealth of features that significantly enhance the tool's utility. Cost-Effectiveness: Compared to its competitors, Quillbot is slightly cheaper than Grammarly but more expensive than LanguageTool. From our perspective, Quillbot doesn't offer more value than LanguageTool, so we believe it should be priced similarly. However, it currently offers significant discounts on their plans, which makes it a very good investment in your writing.

While an account is required, the company assures users that their data is not sold or made public.

Users should be cautious when handling sensitive information.
Conclusion	In our eyes, Grammarly is the best choice for anyone who wants to write professional articles or other things in English. Even though Grammarly has an expensice price tag, you can't get anything better on the market. We have been using Grammarly for a long time now. And even in the world of ChatGPT and other AI tools, Grammarly is just super handy and helpful. For us, the Premium plan is worth every penny. This only applies as long as you are in the English-speaking world. If you need other languages, we would recommend LanguageTool instead.	Quillbot is a flexible AI writing tool that does a great job with paraphrasing and grammar checking. While it has a few minor downsides, like occasional mistakes and some privacy concerns, its overall performance and affordability make it a solid choice. In the end, choosing the best writing tool is also a matter of personal opinion. If you want to improve your writing and boost productivity, Quillbot is definitely worth a look. However, it still cannot compete with Grammarly as the best writing tool in this category. In our eyes, Grammarly is worth the more expensive price.
