| Features Tooltivity's expert score for the 'Features' aspect of each extension. | 9.0 Voilà's features are impressively comprehensive and cover many areas, from simple AI chat to advanced content creation tools.  The integration with Gmail works flawlessly and makes email management much more efficient. The ability to respond to emails in a context-sensitive manner sets the tool apart from many of its competitors.  On websites, it is first necessary to highlight the desired text. However, if you want a summary of the website, for example, this is not a problem because you can simply highlight the entire website. A context-based AI chat that has access to the context of the current website would improve this even further.  Overall, the extension offers very powerful features, some of which are not even found in competitors' products. | 9.5 Sider offers a comprehensive range of functions and is designed to provide a solution for every possible use of AI. From AI writing assistance to PDF analysis, for example, it covers all areas for every blogger. Creatives also get their money's worth here, whether creating images from text or editing photos, Sider offers these functions in just one tool and integrates the functions of other providers into your one tool.  The number of integrated AI models, such as GPT-4o, Claude, or Gemini, also stands out. This ensures that users have access to the latest technology.  In summary, Sider offers almost all of the current possibilities of AI in one tool. Winner in this category |
| Performance Tooltivity's expert score for the 'Performance' aspect of each extension. | 8.7 In our test, Voilà consistently delivered good performance on various websites and in different use cases. The AI responses are usually fast and relevant. The extension has no noticeable impact on browser performance. Some users report occasional delays during peak times, but this is common with AI tools. The tool processes large documents and complex queries without any problems. | 9.2 Sider generally performs well in the test with fast response times and reliable functions. The integration of multiple AI models ensures that users receive accurate and relevant information. However, there can be occasional delays, especially when using advanced features or at peak times. Continuous updates and optimizations could further improve performance. Winner in this category |
| Design Tooltivity's expert score for the 'Design' aspect of each extension. | 9.3 The user interface is clear and intuitive. The seamless integration with Gmail is particularly well done. Winner in this category | 8.5 The design of Sider is very user-friendly, and the interface is quite clear, so it's easy to find anything. The sidebar is great because you can access features without leaving the page. However, it might feel cluttered for some people as there are so many options. A sleeker design could improve the user experience. |
| Value for Money Tooltivity's expert score for the 'Value for Money' aspect of each extension. | 8.9 The free plan offers a good introduction to Voilà's features, but is quite limited. The premium plan for $6 per month offers excellent value for money for anyone who finds that they use the tool regularly after using up their free requests. In our opinion, the advanced features, such as chatting with YouTube videos and generating images, justify the price. For frequent users who also want to use AI for their documents or chat with images, the Ultimate version is worthwhile. At $14, the price is still relatively inexpensive compared to competitors with similar features. Winner in this category | 7.8 While Sider offers a free version with limited requirements, the premium plans can be expensive for casual users. While the feature set justifies the cost for power users, those who only need basic features may find it expensive. The availability of different pricing tiers offers flexibility, but an intermediate solution with a cheaper option could appeal to a wider audience. |
| Ease of Use Tooltivity's expert score for the 'Ease of Use' aspect of each extension. | 9.4 Voilà offers an excellent balance between performance and simplicity. The tutorial system is well-designed and suitable for beginners. The keyboard shortcuts make navigation intuitive once you have learned them. The context-sensitive functions work automatically, so manual configurations are rarely necessary. Creating custom prompts and actions takes some time to learn, but it is worth the effort. Winner in this category | 9.0 In our tests, Sider was easy to use without having to learn how to use it. The tooltips and instructions help you get started right away. It works well in our tests with popular browsers such as Chrome and Edge, which are quick to install and use. However, if you want to delve into the advanced functions, it can take a while to get to grips with everything. Basic users might be a little overwhelmed here. |
| Security & Privacy Tooltivity's expert score for the 'Security & Privacy' aspect of each extension. | 9.0 Data protection is a high priority for Voilà. The extension complies with the GDPR and transparently lists its data processing methods. The tool does not store conversations on its servers, which is important for companies, among others. The privacy policy is comprehensive and explains data usage clearly and concisely. The option to use your own API keys offers additional control and flexibility for anyone who needs it. The only minor criticism is the use of third-party analytics tools, which is a common practice for such extensions. Winner in this category | 8.0 Sider stores the data on Amazon's US servers. The data protection guidelines are transparent and users have control over their data. However, usage data is collected for analysis purposes, which not every user will find acceptable. The assurance that data is never passed on and no spam messages are sent is a positive aspect. |
| Conclusion A summary of our findings and final thoughts for each extension. | Voilà impressed us with its seamless integration, especially with Gmail, and its powerful AI features. It is a tool that simply aims to integrate AI into everyday life for every user in order to simplify everyday tasks. The free plan allows you to test it out sufficiently, and if you're convinced, the Pro plan offers excellent value for anyone who values productivity.

The high number of features, from writing assistance to image editing, makes it a versatile choice for truly anyone. Although it excels in many areas, there is still room for improvement.
