Features
9.0

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.

9.3

Customizable

AdGuard Adblocker offers the option of activating or deactivating all functions yourself.
It also offers an allow list and user-defined rules. This means that you can make adjustments to the rules or allow advertising on certain websites that you want to support.

Performance
8.8

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

9.0

A recent user complained in a review that it had YouTube problems that affected the performance and speed of the website. In our test, we did not notice any performance problems. The extension generally works quickly and reliably. There are also regular updates, so the problem may already have been solved.

Design
9.0

User Interface:
Quillbot boasts a clean and intuitive interface. The layout is straightforward, making it easy for users to navigate through different features without any hassle.

Customization:
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.

9.2

The design is very clear and well-organized. The display of the settings is significant for adblockers. Here, great importance has been attached to user-friendliness and highlighting the customizable settings.

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.

9.2

The free browser extension offers numerous functions that worked perfectly in the test. Compared to competitors, you get many functions here that others offer for a fee.
If further functions are required that can also be used outside the web browser, AdGuard Adblocker also offers an app that is subject to a charge. We consider the current lifetime prices to be fair for the services offered.

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.

9.5

Installation is quick and easy. What impressed us in comparison to other competitors was that AdGuard Adblocker clearly shows which functions it offers and explains them in the introduction, and you can activate them directly if you wish. The extension therefore attaches great importance to ensuring that every user recognizes and uses the options. With competitors, some functions were somewhat hidden in the settings.

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.

8.0

Strong privacy protection by preventing tracking. Also features malware detection and blocking, although public complaints could raise concerns.
Overall, AdGuard provides transparency in its privacy policy and limits data collection. Some practices, such as filing public complaints and reviewing website visits, should be critically questioned.

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.

AdGuard Adblocker is, in our opinion, a very good ad-blocking tool compared to its competitors, offering a range of features in the free extension that you often have to pay for. In our test, all ads were blocked. Other ad blockers currently fail because of YouTube's advertising videos, but AdGuard currently seems to have this fully under control. Overall, it is the choice for a free browser extension with many features.

Finally, we would like to point out that our test is about the browser extension. If you work in different browsers and don't want to install a new extension in each one, or if you work a lot in apps that carry out advertising and tracking, AdGuard Adblocker offers an app for comprehensive security outside the browser.

The AdGuard app allows you to block advertising in other apps outside of your web browser, for example, and keep your data secure. Here is an overview of the additional functions:

Comparison
