Features
8.0

Merlin AI offers a variety of features including summarizing, writing, coding, diagramming and more. It supports multiple AI models such as GPT-4, Claude and Gemini and allows users to create custom AI chatbots and knowledge bases. The platform also integrates with the web and files in real time. However, some features, such as PDF summarization, are not as robust as those of specialized tools. It also lacks what we consider to be the important function of direct communication between AI and the current website. In addition, the function of direct communication between AI and the current website, which we consider important, is missing.

Missing Feature
9.5

In our tests, Toggle Track was found to have a diverse set of features suitable for both individuals and teams. The time tracking function is straightforward and allows users to start and stop it via a button.

start tracking

We were particularly impressed with how detailed the reporting function is. It gives you detailed insights into your productivity and time management to help you improve your efficiency.
Integrating with other applications, such as Notion or Todoist, is also very useful. This is a particular advantage, as processes from other programs can also be integrated, which is not possible with Toogl Tracker itself.

integration

Finally, it should be emphasized how Toggl specializes in larger teams and companies. With the team management functions, seamless collaboration is possible, where you can always see how much time and effort has already gone into a project.

Performance
7.5

Merlin is generally fast and responsive, but it can slow down browsers, especially on older hardware. There are occasional bugs and crashes, though the team releases frequent updates and improvements.

8.0

In our tests, Toggl Track worked reliably and without any major technical problems on various platforms. However, some users reported occasional synchronization problems when switching between devices in the reviews.
The automatic start of time tracking also worked well, only an automatic stop, e.g. when closing the browser, would be desirable. In our test, the timer continued to run for hours because the task was forgotten to end when the browser was closed.

Design
9.1

The design has a modern look and feel, with handy keyboard shortcuts and sidebar integration that make navigation easier. That said, the user interface can feel cluttered and overwhelming, especially for new users, and there are inconsistencies between the extension, web, and mobile versions.

Design
8.3

The design of Toggl Track with its basic functions is clear and intuitive. The dashboard is well organized and provides quick access to the most important functions. When users get to the advanced features, the design could be a little more self-explanatory. It is currently a little confusing and users have to find their way around first.

Value for Money
8.2

The free plan is generous for light users, offering a substantial daily quota and access to a wide range of basic features. The Pro plan is competitively priced, especially when compared to the cost of subscribing to multiple separate AI tools, and unlocks unlimited access to all models and advanced features. However, the absence of a free trial for premium features means users must commit before experiencing the full capabilities of Merlin AI. Additionally, some users report that the query system—where different models and features consume varying amounts of daily queries—can be confusing or feel restrictive, particularly for those trying to understand how far their usage will go on each plan.

8.0

Toggl Track offers a free plan with basic features. If you only want to track your time and only do this on your own, you get a good time-performance ratio here.
However, if you want to use additional functions such as detailed analyses, the premium plans are necessary. For many who only want to use it as a time management tool, the price will probably put them off. If you need and use all the functions, the price-performance ratio with the comprehensive functions and integrations is perfect. For teams and companies, the investment can also be justified by the productivity gains and insights offered.

Ease of Use
8.5

Getting started with Merlin AI is straightforward—installation is quick, and the onboarding process is simple enough for most users to begin using core features right away. However, the platform’s extensive feature set can be overwhelming at first, leading to a noticeable learning curve as users explore everything it offers. Some users have expressed confusion about how the daily query limits work, how different models are selected or switched, and which features are available on each plan. Occasional bugs and log-in issues can also disrupt the workflow, requiring users to troubleshoot or reach out to support. Overall, while Merlin AI is accessible, mastering its full capabilities may take some time and patience, especially for those new to AI tools.

7.0

The Installation and use of the basic functions are very intuitive. No user should have any problems tracking their times here. However, if users want to use the advanced functions, they will need to think a lot about it and take some time to understand everything. There is still room for improvement here so that every user can use them straight away.

Security & Privacy
9.3

Merlin does not sell user data to third parties and only uses data for core functionality. The privacy policy is transparent, but some users remain concerned about the amount of data collected and the permissions required.

8.7

Toggl Track protects user data with standard encryption to protect information and offers options for two-factor authentication. The data protection guidelines are transparent so that everyone can read how their data is handled. The only point deduction is that it would be desirable to be able to control which data authorizations you want to assign yourself. This is also evident from user reviews.

Conclusion

Merlin AI is a powerful and versatile tool that can really boost the productivity of a wide range of users. The integration of multiple AI models and functions into a single extension is ideal for this p

However, Merlin is not completely perfect. We encountered occasional bugs, inconsistencies in the user interface and some performance issues. Pricing can also be confusing, and some features are locked behind a paywall..

Overall, Merlin AI is a good choice for anyone looking for an all-in-one AI assistant for the browser - especially if you value having multiple AI models and tools in one place.

Toggl Track is a reliable tool for both individuals and teams who want to improve their time management. Its comprehensive functions make it an indispensable tool, especially for advanced users. However, the standard user might be a little overwhelmed at first. While it stands out for its numerous integrations, some users might find the price a little too high. Overall, Toggl Track offers good value for money for anyone who can handle its numerous functions.
