Features
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.

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:

Highlighter Popup with four colors

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.

Notes Editor: Adding notes to your highlight

The dashboard where your highlights are stored works well and gives you an overview of all your highlights.

Diigo Dashboard
Performance
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.

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 design is sleek and user-friendly. The customizable backgrounds in the premium plan and widgets make it visually appealing and easy to navigate.

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 The design of Diigo is outdated and could use a modern refresh.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
8.7

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.

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
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.

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
8.0

Momentum takes data protection seriously and offers the option of saving data locally. Nevertheless, some data is collected for functional purposes.

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

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.


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.
