Features Tooltivity's expert score for the 'Features' aspect of each extension. | 8.0 Several features are included in the free Urban VPN Proxy. The most obvious is IP address masking, which allows VPN access to servers in over 80 countries. ![]() An adblocking function is also integrated as an add-on, which reduces unwanted advertising while surfing and also protects against mining websites. ![]() However, advanced security features such as a kill switch or multi-hop connections, which are available in some premium VPNs, are missing here, probably due to the free version. Winner in this category | 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. ![]() Winner in this category |
Performance Tooltivity's expert score for the 'Performance' aspect of each extension. | 5.5 The performance of Urban VPN Proxy was good at the beginning of the tests, the connection speed and server availability were also okay, but could be even better in our tests. Especially at peak times, when the server load is high, you notice a sharp drop in speed. | 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. Winner in this category |
Design Tooltivity's expert score for the 'Design' aspect of each extension. | 8.0 The design of Urban VPN Proxy is clear and simple. Every user is immediately shown the basic functions and these can be switched on and off directly as required. | 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. ![]() Winner in this category |
Value for Money Tooltivity's expert score for the 'Value for Money' aspect of each extension. | 8.0 Urban VPN Proxy is free and has a good price-performance ratio. With access to over 530 servers without a subscription fee, it's perfect for any basic user. You also get additional functions such as adblocking for free. However, it should be noted and clear to everyone that you “pay” for the use by saving your tracked data through the extension. | 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. Winner in this category |
Ease of Use Tooltivity's expert score for the 'Ease of Use' aspect of each extension. | 9.0 Urban VPN Proxy is a very easy-to-use tool overall. The installation process is quick and uncomplicated, and you can start establishing a VPN connection immediately after installation. Every user should have no problems with it, only the performance problems can cause some users to despair. Winner in this category | 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. |
Security & Privacy Tooltivity's expert score for the 'Security & Privacy' aspect of each extension. | 6.0 Urban VPN Proxy offers basic encryption according to OpenVPN standards. Due to the VPN function, you initially browse the websites anonymously. At the same time, however, the service collects precisely this web browsing data for itself. The data is collected in an anonymized format. The browser extension also lacks a clear no-logs policy and other advanced security functions, which also affects the rating in this category. | 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. Winner in this category |
