Grammarly goes beyond basic grammar and spelling checks. It offers advanced features like tone detection, vocabulary enhancement, and generative AI capabilities. Compared to competitors, Grammarly provides a more comprehensive set of tools, making it a valuable asset for any writer.

Performance
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.

9.0

Grammarly performs well across different platforms, providing real-time suggestions without significant lag. The tool is reliable and helps improve writing efficiency.

Design

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.

8.5

The design is clean and intuitive, making it easy to navigate. The color-coded underlines for suggestions are helpful, and the interface is user-friendly. However, some users might find the pop-ups slightly intrusive.

Value for Money
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.

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!

Ease of 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.

Configure
9.0

Grammarly is straightforward to use, with a minimal learning curve. The browser extension integrates seamlessly with various platforms like Google Docs and Gmail, allowing you to get started right away.

Security & Privacy
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.

8.0

Grammarly takes privacy seriously, with stringent security measures in place. While an account is required, the company assures users that their data is not sold or made public. However, some users may still have concerns about data processing.

Conclusion

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

Currently, you have the opportunity to purchase the app as a lifetime plan. Here you can decide whether the app should be installed on 3 or 9 devices.

Pricing

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.
