Features Tooltivity's expert score for the 'Features' aspect of each extension. | 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. ![]() | 9.3 PresentBoard is characterized by its extensive range of functions and offers a variety of widgets to different requirements. ![]() The iCalendar and Google Calendar integration worked perfectly in the test so that you can always keep track of your appointments immediately when you open a new tab. It is also worth taking a look at future updates, where PresentBoard has created a list of additional functions that users can vote on themselves to prioritize for future development. In our opinion, a decisive function that competitors have already partially integrated is the integration of ChatGPT directly as a widget in the dashboard. ![]() Winner in this category |
Performance Tooltivity's expert score for the 'Performance' aspect of each extension. | 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. Winner in this category | 8.0 PresentBoard works reliably once it has been set up. Only when customizing the dashboard can minor problems occur. For example, occasionally clicking on the + symbol did not work, which is annoying when setting up. ![]() Occasional bugs reported by users in the reviews were actively fixed by the developers in regular updates. Overall, the extension delivers a good performance. Winner in this category |
Design Tooltivity's expert score for the 'Design' aspect of each extension. | 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 The design of Diigo is outdated and could use a modern refresh.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. | 9.0 When selecting the design of PresentBoard, importance was placed on both the visual and the functional. Users have almost no limits when it comes to customizing the dashboard. Whether different backgrounds of the dashboard, colors and backgrounds of the texts of widgets or ready-made templates. With a little time, everyone can find the right design. Winner in this category |
Value for Money Tooltivity's expert score for the 'Value for Money' aspect of each 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. | 9.5 PresentBoard offers extensive features for being free. Many features are offered for a fee by competitors, the ones here are free, making it a valuable tool for users who want to increase their productivity at no cost. Only the lack of some functions such as a directly integrated AI model is still decisive here compared to competitors. This is usually offered for a fee, but if it were also offered free of charge here, users would have an unbeatable price-performance ratio. Winner in this category |
Ease of Use Tooltivity's expert score for the 'Ease of Use' aspect of each extension. | 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. | 8.3 There were no problems with the installation process of PresentBoard during the test. After installation, a new tab appears on which users are immediately shown the tutorial video and various sample templates. Great importance was attached to user-friendliness here. This also shows that you do not have to register to use the functions. You only need to log in if you want to save the self-created dashboard in the cloud to avoid losing it. ![]()
In summary, the extension is easy and intuitive to use with the help of the tutorial. However, anyone who wants to set up their dashboard without using the ready-made templates should be aware of the high initial time expenditure. Winner in this category |
Security & Privacy Tooltivity's expert score for the 'Security & Privacy' aspect of each extension. | 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. | 9.0 PresentBoard takes user privacy seriously and ensures that data is not sold to third parties. The data protection regulations are described transparently so that users who value data security are in the right place. The only negative aspect is a security warning from Google when setting up Google Analytics. The application should still be checked here, if you continue to click that you trust PresentBoard, this has no influence on the later use, but this does not inspire good confidence for the user. ![]() Winner in this category |
