| Features Tooltivity's expert score for the 'Features' aspect of each extension. | 8.8 Screencastify offers a robust set of features, including screen and webcam recording, video editing and interactive questions. Leaving aside the fact that many features are only available for a fee, it's fair to say that it offers a lot of features. While recording, you can easily add spotlights and draw on the screen. The drawing tools offer a nice range of options, so you should have everything you need:  The subsequent editor also offers many functions where you can cut the video to your needs. Here is what the basic editor looks like:  It recently also added an AI feature that automatically adds captions, transcripts, titles, and descriptions. Furthermore, Screencastify offers another video editor when clicking "Edit Video" in the top right corner. This will open up another editor where you can do some more video editing. Here is how it looks like:  In our opinion, this editor isn’t necessary if you already have your own video editing software, but it could be useful for some people. We’re not entirely sure if this is just an older version of the original editor. However, we did discover that you can export videos to MP4 for free, thanks to an "Export" button that lets you do so without any limitations. We’re not certain if this is intentional, but at least it works for us. 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.  |
| Performance Tooltivity's expert score for the 'Performance' aspect of each extension. | 7.5 The speed has deteriorated considerably with the latest updates. This is probably because more and more functions, such as the AI function, are being added. The tool has become slower, and creating links or accessing older videos takes longer than before. Many users have also complained about the performance in the reviews. Winner in this category | 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. | 9.0 The design is intuitive and user-friendly. We think that navigation is very intuitive despite the many functions. | 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. | 5.0 As already mentioned, we are somewhat shocked by the limitations of the free version. Especially if you have used the app in the past and can export videos for free. In addition, even with the starter package for $7, you are limited to 10 exports. We find that many other providers offer much more for the 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.

| Ease of Use Tooltivity's expert score for the 'Ease of Use' aspect of each extension. | 8.5 Screencastify is easy to use, with a minimal learning curve. Even beginners can quickly get the hang of it. However, we find that recent updates have introduced some complexities that are not absolutely necessary for a screen recorder. 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. Winner in this category |
| Security & Privacy Tooltivity's expert score for the 'Security & Privacy' aspect of each extension. | 8.0 Unfortunately, an account is required, which in our opinion is not necessary for Screen recorder. However, Screencastify's privacy policy is very comprehensive and complies with standard data protection practices, including compliance with the GDPR and PCI-DSS certification for payment data. Screencastify takes reasonable security measures but, like all online services, cannot guarantee absolute protection. | 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 |
| Conclusion A summary of our findings and final thoughts for each extension. | Screencastify was a fantastic tool in the past, and we used to use it daily. Unfortunately, recent updates have made it less user-friendly by hiding key features behind a paywall. For people who need a wide range of features, the tool is still an option. For others who just want to make a recording every now and then to export a video, Screencastify is unfortunately no longer an option. | 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. |
