Features
8.0

OneNote Web Clipper basic functions for saving web content.
In addition to saving an entire page, you can also save individual markers.

In addition, screenshots of the entire page or only parts of a page can be created.

An important function of the Web Clipper is that a preview is created directly when clipping and can be edited directly, for example by rewriting or highlighting text before it is synchronized with OneNote.

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
Performance
9.0

The Performance was good in our tests and there were no problems. All content could be saved and transferred to the OneNote notebooks without any problems. The only performance problems mentioned by some users in the reviews are that there are sometimes synchronization problems. We were unable to reproduce this.

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.

Design
8.5

The design is clear and simple, so even basic users can get started immediately without any problems. However, it could offer a few more customization options to suit individual preferences.

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
Value for Money
9.2

As the tool is free, it offers excellent value for money. You get basic functions for saving web content. The required OneNote can also be used with certain restrictions; a paid version of Office for $69.99 per year is also not overpriced.

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
9.3

The tool is very user-friendly and has a low and fast learning curve. Most users should find it easy to start cutting and organizing content straight away. There are only a few functions that are not self-explanatory.

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
9.0

OneNote Web Clipper is from Microsoft. The same privacy policies apply when using other products such as Word, Excel, or similar.

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.

Conclusion

Overall, OneNote Web Clipper is a useful tool for anyone who simply needs to collect, store, and organize web content. It offers a number of features that make it easy to clip, annotate, and organize information. If additional features are needed on top of these basic features, other competitors should be looked at.

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.
