Features Tooltivity's expert score for the 'Features' aspect of each extension. | 8.5 Momentum offers a comprehensive set of features that are both useful and easy to use. The focus mode and to-do list are particularly standout features, but some advanced functionalities are locked behind the premium plan. Winner in this category | 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. ![]() Winner in this category |
Performance Tooltivity's expert score for the 'Performance' aspect of each extension. | 9.0 Momentum runs smoothly without any noticeable lag or performance issues. It integrates well with various browsers and does not slow down your browsing experience. Winner in this category | 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 Tooltivity's expert score for the 'Design' aspect of each extension. | 9.0 The design is sleek and user-friendly. The customizable backgrounds in the premium plan and widgets make it visually appealing and easy to navigate. Winner in this category | 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 The design of Diigo is outdated and could use a modern refresh.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 Tooltivity's expert score for the 'Value for Money' aspect of each extension. | 8.7 The free version offers basic functions for creating to do lists and occasionally using the focus mode. The premium plan offers considerable added value with additional customizations and integrations. Winner in this category | 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 Tooltivity's expert score for the 'Ease of Use' aspect of each extension. | 9.2 Momentum is straightforward to set up and use. The First Start Tour describes the basic functions to everyone in just a few steps so that you can work in a focused manner after just 2 minutes. The minimal learning curve makes it accessible for users of all skill levels. Winner in this category | 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 Tooltivity's expert score for the 'Security & Privacy' aspect of each extension. | 8.0 Momentum takes data protection seriously and offers the option of saving data locally. Nevertheless, some data is collected for functional purposes. Winner in this category | 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 A summary of our findings and final thoughts for each extension. | Momentum is a fantastic choice for anyone looking to enhance their productivity with a visually appealing and functional new tab page. If you're okay with the basic features and don't mind the occasional upsell for premium features, Momentum can be a valuable addition to your productivity toolkit. With the premium plan, you can unlock even more customization options and integrations that can make your workflow smoother. Overall, Momentum is an excellent addition to any productivity toolkit. | Diigo is a handy tool for collecting stuff from the web, like bookmarks, highlights, and notes.
