Features	9.2 Recall's range of functions is impressive for a relatively new tool. The AI summary works on a wide range of content, from articles to YouTube videos with a running time of several hours. We particularly liked the personal knowledge base and the way Recall automatically links related content. Spaced Repetition and Active Recall are outstanding features for students. However, some features are still in beta or will be available soon. The functions in the free version are severely limited in the number of users per day, and there is an upper limit for free use.	9.3 AdBlocker Ultimate offers a wide range of features that effectively block ads on websites, YouTube and social media platforms. Ad Blocking: Ads are prevented on various platforms, both on the website and as pop-ups. There are other additional functions here, such as blocking all irritating in-page popups, cookie notices and third-party widgets, which substantially decrease page loading times. The settings can also be used to remove only country-specific advertising and a whitelist can be added. Privacy Filter Blocks an extensive list of various online trackers, counters and web analytics tools. Based on the EasyList Privacy list and upgraded by our team. Additionally you can use the Fanboy's Social Blocking List which Removes social media integration. Security: The Security Filter automatically blocks all malicious domains. The listed filters can all be switched on and off separately and individually.
Performance	9.0 Retrieval is fast and reliable in most cases. The summary is fast, even with very extreme examples such as a 9-hour news show that we had summarized in our test. Occasionally, we encountered errors or slowdowns, especially when asking further questions about the summarized content via the wizard. The team is actively working on performance improvements and there are regular updates. Overall, the tool feels stable and is suitable for everyday use.	9.0 During our test, AdBlocker Ultimate did not experience any performance issues. Ad blocking worked flawlessly on all platforms tested, so there were no disruptions to websites caused by advertising.
Design	9.0 The user interface has a clear and modern design. The focus is on user-friendliness. We found the browser extension intuitive and easy to navigate. The tagging and organization system can be used flexibly, and some users mentioned minor bugs in the user interface, but these were only minimally noticeable in the test.	8.5 The user interface is clearly laid out and should be easy to use for every user. The settings page is also very clearly laid out. Only the constant reference in the extension pop-up to the paid Windows desktop version detracts somewhat from the design.
Value for Money	8.1 The free tariff is suitable for infrequent users who do not need all the functions, as you will quickly reach the map limit. However, if you want to use the extension on a day-to-day basis, you cannot avoid the extension. The paid plan is competitively priced, especially with the student discount. We appreciate that some features will remain free forever, and the team is open to feedback on pricing. Compared to alternatives, Recall offers good value for money for those who need advanced knowledge management features, but casual users may find the limitations too restrictive and stop using the extension.	9.5 The Web Extension is free of charge. Compared to other free providers, it offers a very high number of functions and options for customizable functions. We would therefore rate the price-performance ratio as very good.
Ease of Use	8.0 An account is required to use Recall. However, due to the integration with a Google and Apple login, this should be easy for everyone. Saving and summarizing content is a one-click process that is well explained at the beginning. However, mastering all functions (e.g., nested tags, links, and spatial repetitions) requires some time and some searching, which can lead to many users not being able to exploit the full potential.	9.0 AdBlocker Ultimate is easy to install and can be used immediately afterwards. Even beginners should find the extra functions easy to use, as they are described in detail. Great importance has been attached to the individual settings for each user.
Security & Privacy	9.9 Recall is characterized by its privacy-friendly approach. User data is not used by the extension for advertising, profiling, or AI training. All content is stored securely, and users retain full control over their data. Data can be exported for inspection or deleted at any time. The data protection guidelines are transparent, and support is always available to answer questions about data protection. We were unable to identify any uncertainties during our review.	8.2 The tool offers the function of extra privacy protection by preventing tracking and thus increasing online security. However, it is not entirely transparent in the policies whether the data collected by the extension is passed on to third parties.
Conclusion	Recall impressed us with its useful intelligent use of AI and its focus on helping users in their everyday lives, especially when learning. The browser extension makes it easy to capture content, and the revision features with auto-generated questions are a real bonus for learners. For occasional users, the free version may be enough, but if you want to use the extension, you can't avoid the paid version. The extension is not yet perfect and has small bugs, but the team reacts quickly to these and feedback, and many new functions are currently being introduced. Overall, Recall is a good choice for anyone looking to do more than just bookmark cards and build a personal knowledge base. If you're tired of forgetting what you've read online and want to save time, it's a must!	AdBlocker Ultimate is a great extension for blocking ads. Ads on various platforms are removed without the user noticing. Particularly noteworthy are the various options for customizing the settings. The user can control whether the extensions should only be responsible for blocking ads or whether they should also offer support in the areas of data protection and security. Compared to other ad blockers, the additional function of blocking cookie banners stood out, which we no longer want to do without. Overall, we consider AdBlocker Ultimate with its wide range of additional functions to be a reliable option for anyone who wants to remove advertising from their online experience.
