Privacy Filter ![]() Security: The listed filters can all be switched on and off separately and individually. Winner in this category | 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. |

Ad blocking worked flawlessly on all platforms tested, so there were no disruptions to websites caused by advertising. Winner in this category | 9.0 Retrieval is fast and reliable in most cases.

Design Tooltivity's expert score for the 'Design' aspect of each extension. | 8.5 The user interface is clearly laid out and should be easy to use for every user.

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. Winner in this category |
Value for Money Tooltivity's expert score for the 'Value for Money' aspect of each 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.
