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.	8.5 Diigo offers basic features for a highlighter and bookmarking tool. It works well and we were able to highlight most websites and they were recreated when revisiting them. The highlighter popup makes it easy to highlight text offering 4 colors. It looks like this: We would have wished to have more color options. Also, note-taking and the tagging functionality are working, but its design does not look appealing. The dashboard where your highlights are stored works well and gives you an overview of all your highlights.
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.	8.0 Diigo performs well in terms of highlighting and syncing across devices. The fact that highlights are always synchronized can cause some loading delays. It's not as fast as other highlighters that use an offline-first approach, but it works reasonably well. However, the unreliable link creation feature and the simple sidebar outliner design need improvement.
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.	7.0 The design fulfills its functionality. The design of Diigo is outdated and could use a modern refresh. The lack of a nice overview of all your highlights on the page itself means you have to open the dashboard on diigo.com instead. The dashboard on diigo.com is okay, but other highlighters like Web Highlights have a much nicer user interface.
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.	8.0 The free version of Diigo offers basic features and is fine for most users. The paid plans are reasonably priced and similar to other highlighters. However, we think other highlighters offer more value for the same price.
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.	7.8 Diigo is fairly easy to use, but the sidebar outliner takes some time to get used to. You can't see all your highlights on the page itself, so you have to go to the dashboard on diigo.com. We wish there was a sidebar to quickly access all our highlighted pages, like in the Web Highlights extension.
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.	7.5 Diigo takes reasonable steps to protect user data. However, since you need an account and your data is stored in their database, absolute protection can't be guaranteed. We think a highlighter should work without needing to sign up, but this feature is missing in Diigo.
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!	Diigo is a handy tool for collecting stuff from the web, like bookmarks, highlights, and notes. It’s a good deal with its premium plans, but the old-fashioned design and limited highlight colors might be a turn-off. If you want something that looks nicer and offers more customization, check out alternatives like Web Highlights.
