Features Tooltivity's expert score for the 'Features' aspect of each extension. | 9.3 Ad Blocker:In our tests, ad banners and ad videos were blocked on all websites, including YouTube and Twitch. Blocked ads also include social media widgets and pop-ups, among other things. ![]() Privacy and Malware Protection:The extension blocks tracking by blocking third-party trackers on all websites and protects your personal data. It also detects and blocks malicious websites and spyware. ![]() CustomizableAdGuard Adblocker offers the option of activating or deactivating all functions yourself. Winner in this category | 8.8 The AI writing aid worked very well in the test with emails, customer responses, and short formats. We particularly liked the dynamic templates, which adapt according to user input. The extension can therefore be adapted for both commercial use, such as quickly replying to emails, and for everyday private use. From summaries to social media texts, this helped enormously in the test. In particular, learners such as students should have a special added value here, for example, through summaries that can be created quickly. ![]()

Performance Tooltivity's expert score for the 'Performance' aspect of each extension. | 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. Winner in this category | 8.9 In our test, AI Blaze worked reliably on most websites and in various applications. The only thing that was immediately noticeable at the beginning was that the functions do not work in the Chrome Store, so websites may prevent access for the extension, but this did not otherwise occur in the test. ![]() The text expansion works immediately, and the AI-controlled functions generally respond quickly, depending on the model selected. When using the most advanced AI models for complex tasks, there were occasional short delays, but these were minimal. |
Design Tooltivity's expert score for the 'Design' aspect of each extension. | 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. Winner in this category | 8.8 The clear, intuitive user interface should also make AI Blaze possible for private users who are not so tech-savvy. The integration into the sidebar is very well done and offers a seamless integration into the design of the browser. |
Value for Money Tooltivity's expert score for the 'Value for Money' aspect of each extension. | 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. Winner in this category | 9.0 In this area, a clear distinction must be made between private and commercial users. For the private user, AI Blaze already offers enough functionality for most people in the free plan. Here we also appreciate the Academic Edition, which offers students and teachers extended, free access. The Pro plan could be too high for private users at $20/month with annual billing. For businesses, however, AI Blaze's Pro plan offers exceptional value compared to similar productivity tools. The time savings alone can justify the investment for most users. For those who want to work in teams, AI Blaze offers the Business plan for $24/user/month. This includes additional comprehensive functions for collaboration and improved communication processes. Compared to alternatives, AI Blaze offers a competitive feature set at a reasonable price for businesses. The ROI is clear after just a few days of regular use, especially for those who frequently write similar messages. |
Ease of Use Tooltivity's expert score for the 'Ease of Use' aspect of each extension. | 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. ![]() Winner in this category | 9.0 For basic functions such as using templates and simple shortcuts, AI Blaze is extremely straightforward. New users can start using the ready-made templates within minutes, and they are well-explained. If you don't want to use the predefined shortcuts, you can create your own commands immediately, which makes it easier to remember the shortcuts in everyday life. We found the shortcuts intuitive and time-saving once you have memorized them. The search function makes it easy to find the right snippet quickly, even as the library grows. The advanced functions do require a certain amount of learning, but the basic functions are easily accessible straight away. |
Security & Privacy Tooltivity's expert score for the 'Security & Privacy' aspect of each extension. | 8.0 Strong privacy protection by preventing tracking. Also features malware detection and blocking, although public complaints could raise concerns. | 9.7 AI Blaze takes security very seriously and holds a SOC 2 certification, which confirms that a company has implemented appropriate controls and procedures for IT systems, data protection, and data security. The company's privacy policies are transparent from the user's perspective in terms of how data is handled, and no user data is sold to third parties. The Business and Enterprise plans offer additional security features such as SAML SSO integration and audit logs. Choosing between different AI models gives users more control over their data. The company is transparent about its use of cookies and analytics and provides clear options for managing settings. There is also the option to allow the extension only to use marked areas for answers, normally, the AI uses the entire website content to have a better data basis. ![]() Winner in this category |
Conclusion A summary of our findings and final thoughts for each extension. | 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: ![]() 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. ![]() | AI Blaze shows that it is an impressive productivity tool that delivers on its promise of saving time and optimizing communication. The user interface is intuitive and well-designed, making it accessible even for those without experience with AI tools. You can tell that companies in particular are also a target group. The ability to customize templates and train the AI to match your brand's voice is particularly valuable here. While the free version is somewhat limited, the affordable pricing of the paid plans makes it accessible to businesses of all sizes. The time savings alone justify the investment for teams that frequently send similar messages or create repetitive content. Individuals, however, may find it too expensive. |
