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. ![]() | 9.2 Matter's feature set is imposing, offering a comprehensive suite of tools that enhance the reading and listening experience. The AI transcription capabilities are particularly noteworthy, as they accurately convert spoken content into readable text. ![]() The speed listening feature with natural-sounding voices is a game-changer for consuming content efficiently. The integration options with popular services like Kindle and Gmail make it a versatile tool for content management. The regular updates and improvements show a commitment to enhancing the user experience. 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. | 9.2 Matter delivers reliable performance across all its features. Content processing is fast and efficient, handling various file types and formats smoothly. The sync capabilities work reliably across devices, ensuring content is always up to date. The tool uses system resources efficiently, maintaining good performance even with multiple features in use. Response times are quick, providing a snappy user experience. The stability across different platforms is impressive, though occasional minor issues may occur during heavy usage. 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 The design of Diigo is outdated and could use a modern refresh.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. | 8.8 The interface design is clean and modern, making it easy to navigate through different features. The layout is intuitive, with a clear hierarchy that helps users find what they need quickly. The mobile-responsive design ensures a smooth experience across devices. While the design is generally excellent, there's room for improvement in some areas of the mobile interface. 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. | 9.3 The free tier offers substantial value, providing access to most essential features without cost. The premium pricing is competitive compared to similar tools in the market. Regular feature updates ensure that users get ongoing value from their subscription. The cross-platform access adds significant value for users who work across multiple devices. 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. | 9.0 Matter is very user-friendly, with a straightforward setup process that gets users started quickly. The controls are intuitive and well-placed, making it easy to access key features. The content organization system is logical and easy to understand. The onboarding process is helpful, guiding new users through the main features. The learning curve is minimal, allowing users to get the most out of the tool without extensive training. 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. | 8.7 The tool takes security seriously, implementing robust data encryption to protect user information. The privacy-focused design ensures that user data is handled responsibly. The company maintains transparency about data handling practices through a clear privacy policy. Regular security updates help maintain a secure environment. While the security measures are solid, some users might want more control over their data sharing preferences. Winner in this category |
