| Performance Tooltivity's expert score for the 'Performance' aspect of each extension. | 8.8 Quillbot performs well with small to medium-sized texts, but it can slow down when processing larger documents. | 9.2 Sider generally performs well in the test with fast response times and reliable functions.

| Design Tooltivity's expert score for the 'Design' aspect of each extension. | 9.0 User Interface: Customization: Winner in this category | 8.5 The design of Sider is very user-friendly, and the interface is quite clear, so it's easy to find anything. The sidebar is great because you can access features without leaving the page. However, it might feel cluttered for some people as there are so many options. A sleeker design could improve the user experience. |
| Value for Money Tooltivity's expert score for the 'Value for Money' aspect of each extension. | 9.0 Free vs. Paid: Cost-Effectiveness: Winner in this category | 7.8 While Sider offers a free version with limited requirements, the premium plans can be expensive for casual users. While the feature set justifies the cost for power users, those who only need basic features may find it expensive. The availability of different pricing tiers offers flexibility, but an intermediate solution with a cheaper option could appeal to a wider audience. |
| Ease of Use Tooltivity's expert score for the 'Ease of Use' aspect of each extension. | 7.8 Quillbot's onboarding process is impressive, and the tool is easy to use right from the start. We quickly grasped most of its features. However, when compared to top competitors like Grammarly, it doesn't feel quite as natural or seamless to use. | 9.0 In our tests, Sider was easy to use without having to learn how to use it. The tooltips and instructions help you get started right away. It works well in our tests with popular browsers such as Chrome and Edge, which are quick to install and use. However, if you want to delve into the advanced functions, it can take a while to get to grips with everything. Basic users might be a little overwhelmed here. Winner in this category |
| Security & Privacy Tooltivity's expert score for the 'Security & Privacy' aspect of each extension. | 8.8 Data Handling: Third-Party Services: Winner in this category | 8.0 Sider stores the data on Amazon's US servers. The data protection guidelines are transparent and users have control over their data. However, usage data is collected for analysis purposes, which not every user will find acceptable. The assurance that data is never passed on and no spam messages are sent is a positive aspect. |
| Conclusion A summary of our findings and final thoughts for each extension. | Quillbot is a flexible AI writing tool that does a great job with paraphrasing and grammar checking. While it has a few minor downsides, like occasional mistakes and some privacy concerns, its overall performance and affordability make it a solid choice. In the end, choosing the best writing tool is also a matter of personal opinion. If you want to improve your writing and boost productivity, Quillbot is definitely worth a look. However, it still cannot compete with Grammarly as the best writing tool in this category. In our eyes, Grammarly is worth the more expensive price. | Sider is an AI tool that can significantly increase user productivity across multiple platforms. The high number of features, from writing assistance to image editing, makes it a versatile choice for truly anyone. Although it excels in many areas, there is still room for improvement. In particular, the sometimes high prices will put normal users off. Overall, Sider is a valuable tool for anyone who wants to combine almost all the possibilities of AI in one tool and is willing to pay for it. |
