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 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 is clean and intuitive, making it easy to navigate. The color-coded underlines for suggestions are helpful, and the interface is user-friendly. However, some users might find the pop-ups slightly intrusive.

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.

8.5

While Grammarly offers a free version, the Premium plan is relatively expensive. However, the advanced features and comprehensive feedback justify the cost for those who need a robust writing assistant.

Grammarly is the priciest option for a reason—because, in our view, it's the best writing tool available in its category. If you're looking for the best writing assistant, go for the Premium plan, you won't regret it!

Ease of Use

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.

8.0

Grammarly takes privacy seriously, with stringent security measures in place. While an account is required, the company assures users that their data is not sold or made public. However, some users may still have concerns about data processing.

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

In our eyes, Grammarly is the best choice for anyone who wants to write professional articles or other things in English.

Even though Grammarly has an expensice price tag, you can't get anything better on the market. We have been using Grammarly for a long time now. And even in the world of ChatGPT and other AI tools, Grammarly is just super handy and helpful. For us, the Premium plan is worth every penny.

This only applies as long as you are in the English-speaking world. If you need other languages, we would recommend LanguageTool instead.
