Paraphrasing Tool:
Quillbot's paraphrasing tool is one of its standout features. 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. However, it sometimes flagged correct sentences as incorrect, which can be a bit annoying.

Summarizer:
Quillbot's summarizer is effective for condensing long articles or papers. It provides concise summaries that capture the main points, making it a valuable tool for students and professionals alike.

9.5

The ChatGPT sidebar offers many useful AI functions that help with a wide range of everyday tasks, but can also help in the business sector.

Users can access real-time data with Web Access, which is a huge advantage over other models. The multi-model group chat function enables users to communicate with several AI models at the same time and thus gain different insights. In addition, the tool supports interaction with images and files, allowing users to analyze images and chat directly with PDFs. These worked flawlessly in the test.

Performance
8.8

Quillbot performs well with small to medium-sized texts, but it can slow down when processing larger documents.

8.0

In testing, the performance of the ChatGPT Sidebar was good. You hardly notice any lag, which ensures a smooth and efficient browsing experience. Only the function of loading marked content directly into the sidebar via a pop-up, asking questions, or summarizing the content had a few problems. Sometimes it was not possible to click on the pop-up after highlighting.

Design

The tool offers various customization options, such as different paraphrasing modes and the ability to adjust the length of summaries. These features make it adaptable to different writing needs.

9.0

The ChatGPT sidebar is designed to be intuitive and user-friendly. Even the basic user should have no problems navigating through all the functions. The interface looks modern and aesthetically pleasing. Several customizable settings allow the tool to be adapted individually, but there could be a few more functions here.

Value for Money
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.

8.3

The ChatGPT Sidebar offers a free version with basic features and a limited number of queries.
However, if you want to use functions such as Web Access, you need the premium version. The premium features might be a bit expensive for the basic user, but for anyone who needs the advanced features, they are still fine. Compared to alternatives, the price is competitive and offers good value for money.

Ease of Use
7.8

Quillbot's onboarding process is impressive, and the tool is easy to use right from the start. We quickly grasped most of its features. However, when compared to top competitors like Grammarly, it doesn't feel quite as natural or seamless to use.

9.0

The ChatGPT sidebar offers an uncomplicated setup process, with the basics presented in the tutorial immediately after installation. Every user should have no problem using all the functions here, as they are also very clearly presented. Should questions or problems nevertheless need to be resolved, many users have commented in their reviews on how responsive the support team is.

Security & Privacy
8.8

Data Handling:
Quillbot ensures that user data is encrypted and securely stored. However, like many AI tools, it does send data to its servers for processing, which may raise privacy concerns for some users.

Third-Party Services:
The tool uses third-party services for certain features, which could lead to data being processed outside of the EU. Users should be cautious when handling sensitive information.

9.7

Security and data protection are a top priority in the ChatGPT Sidebar. No personal data is collected in the extension. The user settings are saved locally so that the data remains private. The tool's transparent data protection guidelines and regular security updates set the extension apart from the competition.

Conclusion

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.

The ChatGPT Sidebar is the perfect tool to improve productivity by integrating AI into daily browsing. The many features make it a valuable asset for personal and professional use. While it stands out for its functionality and ease of use, the premium price might be too high for regular users. Overall, however, it is a highly recommended tool for anyone who wants to use AI for their daily tasks.
