Features

Nowadays, websites request data through third parties. The local CDN emulation offered by Decentraleyes is a unique and effective feature that blocker competitors currently lack. This means that the same locally stored data is always sent directly to the websites before they can even request relevant private data.

CDN


The extension is aware that this function is only an additional function and advertises it as being used in addition to regular ad blockers. The extension could be expanded here and offer these additional functions directly so that you have them all in one extension.

Another advantage of the extension is that the code is completely open source and can be found on GitLab. This ensures transparency and trust.

9.0

LanguageTool offers a comprehensive set of features that go beyond basic grammar and spelling checks. It supports over 20 languages, making it a versatile tool for multilingual users. The advanced grammar checks are particularly impressive, catching complex issues that many other tools miss. Compared to competitors like Grammarly, LanguageTool holds its own with unique features like custom dictionaries and plagiarism detection.

Performance
9.3

The extension offers a noticeable improvement in page load times. We did not find any problems in our tests, but according to user reviews, there are occasional compatibility problems with certain websites. However, according to Decentraleyes, these are constantly being fixed by updates.

8.0

LanguageTool does a good job of spotting grammar and style issues. However, it can take a while to process longer texts, and sometimes, clicking on suggestions causes the page to jump to the top, which can be a bit frustrating.

Design
9.5

The design is intuitive and simple. This also includes the settings menu.

8.0

The design is clean and intuitive, making it easy for users to navigate and utilize the tool effectively. The browser integration is seamless, and the user interface is straightforward.

Value for Money
9.5

The extension is completely free to use with optional donations. The price-performance ratio is therefore perfect, as functions that are not offered by other providers are made available here free of charge. Only the lack of further functions in the area of ad blocking results in deductions.

9.5

The free version gives you the basics, but the premium version really shines with its advanced features.

While Grammarly can be expensive, LanguageTool offers great value at a more affordable price. So, if you’re seeking a budget-friendly alternative to Grammarly, LanguageTool is a solid choice.

Ease of Use
9.9

The extension is characterized by its user-friendliness. Installation is very simple and you have the option of testing the function immediately on the website. When you open the website https://decentraleyes.org/test/, you are shown whether the function works and an example of what it looks like in the icon when data is blocked.

The settings are also very well described so that even beginners should have no problems here. Advanced users can also read the complete documentation or the code on GitLab.

9.0

LanguageTool is very user-friendly, with a minimal learning curve. Most users will find it easy to get started and make the most of its features right out of the box.

Security & Privacy
9.2

The extension offers strong features in the area of data protection, so it goes without saying that it scores well in this area. The open-source code allows anyone to review the extension in detail. Only the lack of a proper privacy policy detracts from this for beginners, who can do little with the code. There is a privacy policy that states in one sentence that no data is collected. However, this should be a little more detailed.

9.5

LanguageTool takes privacy seriously. No account is required for basic features, and the tool ensures that user data is not sold or made public. This focus on privacy is a significant plus.

LanguageTool states that it is GDPR compliant which makes it especially interesting for users in Europe.

Conclusion

Decentraleyes is a valuable tool for anyone who wants more privacy and faster browsing. With local CDN emulation, Decentraleyes has features that bring both security and performance benefits. While it currently excels in this one area, you need to be aware that websites also make adjustments and it won't always work 100% of the time, especially without further updates.
Overall, Decentraleyes is a recommended choice for privacy-conscious users as an addition to the usual ad blockers.

LanguageTool is a reliable and efficient writing assistant that supports multiple languages. Its advanced grammar and style checks make it a valuable tool for writers and professionals. While the premium version offers excellent features, the free version is somewhat limited. Overall, LanguageTool is a solid choice for anyone looking to improve their writing.

Compared to Grammarly, LanguageTool holds its own, especially if you need to write in multiple languages. When it comes to writing in different languages, LanguageTool is the way to go. But if you’re only writing in English, Grammarly still delivers better results.
