Features	9.3 Todoist offers comprehensive functions for task management. Tasks can be prioritized, labeled and filtered. Another good feature is that websites can be saved directly as tasks. This can be done via the taskbar button or by right-clicking. In this way, information on a website can be added directly as a task that you want to edit or read up on later. The extension can also be used to mark tasks directly as completed. Other features like collaborating on projects and tracking progress with personalized productivity trends add further value. Some of these advanced features of the application, such as customized templates and advanced reports, are available in the paid plans.	9.5 Sider offers a comprehensive range of functions and is designed to provide a solution for every possible use of AI. From AI writing assistance to PDF analysis, for example, it covers all areas for every blogger. Creatives also get their money's worth here, whether creating images from text or editing photos, Sider offers these functions in just one tool and integrates the functions of other providers into your one tool. The number of integrated AI models, such as GPT-4o, Claude, or Gemini, also stands out. This ensures that users have access to the latest technology. In summary, Sider offers almost all of the current possibilities of AI in one tool.
Performance	7.3 Most of Todoist's functions worked quickly and without problems in our tests. The function of connecting the account with the Google Calendar to display your appointments did not work in the test, an error message was displayed. Users also report occasional delays in synchronization in the extension in the reviews.	9.2 Sider generally performs well in the test with fast response times and reliable functions. The integration of multiple AI models ensures that users receive accurate and relevant information. However, there can be occasional delays, especially when using advanced features or at peak times. Continuous updates and optimizations could further improve performance.
Design	9.5 The design is clean and intuitive, making it easy to navigate immediately. The interface can also be visually customized to suit your needs, but these are not overdone. The option of color-coded priority levels and project labels also helps with organization.	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	9.0 The functions of the Todoist extension are free of charge. The free functions of the Todoist application should also be sufficient for most users. For users who want to use functions such as reminders or additional view options, the price should also be reasonable. With an annual payment installment, $4 per month is reasonable in our view.	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	9.0 In our test, we had no problems with the installation and the first steps. The creation of tasks and overall use is self-explanatory. There are also many instructions and tutorials already available for the tool. For more experienced users, there are also additional functions in the application that can be used with simple shortcuts.	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.
Security & Privacy	9.0 Todoist describes its data security in detail in its Privacy Policy. This states that the data is encrypted according to the state of the art and that regular security updates are carried out. The data is stored in the cloud for synchronization; it cannot be stored locally.	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	Todoist is a great option for task management. We really like its simplicity, which is likely why it has become so popular. While some modern tools may offer more features, Todoist is one of the best choices if you’re looking for a solid, beautifully designed to-do list. Still, we noticed some performance issues. The extension takes longer to load when working in environments with a bad internet connection. It’s not a dealbreaker, but something to be aware of, especially if you often work in places with poor internet. Overall, Todoist is a strong choice for anyone seeking an easy-to-use and powerful task manager, though its speed and offline capabilities could be improved. If you would like to test Todoist yourself, you can use our code to get the Pro version for 2 months free of charge. https://get.todoist.io/mgs7dk	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.
