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
7.0

TimeOWare offers basic functions for checking the time spent on websites. These include time recording on websites, where the percentage of total time taken up by each website is displayed directly in real-time in a statistic.

Another feature is the blocking of websites. Websites can easily be blocked manually if you think that you no longer want to use this website. Here we would like to see the manual blocking of websites.

However, it lacks advanced features such as detailed analytics or customizable alerts that some users may find useful. Nevertheless, the core features are well implemented and serve the main purpose of improving digital well-being.

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.

9.0

TimeOWare works reliably, with no noticeable slowdowns or performance issues during use.
The extension runs in the background and provides real-time updates on time spent without affecting browser speed.

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
7.5

The design of TimeOWare is clear and intuitive, making it easy to find your way around immediately. All available functions can be used directly. The minimalist interface ensures that users are clearly shown which websites may pose problems for their digital well-being. In our tests, however, we found that there could be a little more customization options to adapt the displays to our own needs.

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.

9.0

As a completely free tool, TimeOWare offers excellent value for money as it provides essential time management features at no cost whatsoever.
The open-source nature of the extension also adds value as it allows users to review and modify the code if desired.
The only reason it doesn't get full marks is that some features offered by competitors are not yet available.

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.

8.5

TimeOWare is easy to use, with little set-up time.
Once installed, it starts tracking time immediately. Likewise, the limited settings are self-explanatory and should be easy for anyone to understand.

In our tests, we noticed that if several tabs are opened next to each other, they are also added up in the extension at the same time. The total number of hours is therefore higher than the actual number in the browser. This can be somewhat confusing for new users.

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.

10

TimeOWare is characterized by security and privacy, as it does not transmit any user data to the outside world and all information is only stored offline on the user's device.
This privacy-focused approach is a key benefit for users who are concerned about data security. Users can also check the code used on GitHub themselves if they have any concerns.

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.

TimeOWare is a great choice for anyone who wants to manage their online time more effectively and realize how much time is spent on websites.

Its simple design and privacy-focused approach make it, in our opinion, a standout option in the time management space.

We felt in testing that a little more customization and even more features could further improve the extension. Overall, however, we think TimeOWare is already a valuable tool for anyone looking to improve their digital well-being.
