| 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 Grammarly goes beyond basic grammar and spelling checks. It offers advanced features like tone detection, vocabulary enhancement, and generative AI capabilities. Compared to competitors, Grammarly provides a more comprehensive set of tools, making it a valuable asset for any writer. 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. | 9.0 Grammarly performs well across different platforms, providing real-time suggestions without significant lag. The tool is reliable and helps improve writing efficiency. 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 is clean and intuitive, making it easy to navigate. The color-coded underlines for suggestions are helpful, and the interface is user-friendly. However, some users might find the pop-ups slightly intrusive. |
| 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 | 8.5 While Grammarly offers a free version, the Premium plan is relatively expensive. However, the advanced features and comprehensive feedback justify the cost for those who need a robust writing assistant. Grammarly is the priciest option for a reason—because, in our view, it's the best writing tool available in its category. If you're looking for the best writing assistant, go for the Premium plan, you won't regret it! |
| 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 Grammarly is straightforward to use, with a minimal learning curve. The browser extension integrates seamlessly with various platforms like Google Docs and Gmail, allowing you to get started right away. |
| 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 Grammarly takes privacy seriously, with stringent security measures in place. While an account is required, the company assures users that their data is not sold or made public. However, some users may still have concerns about data processing. |
| 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 tool's ability to respond to emails contextually and directly integrate highlighted text from any website sets it apart from the competition. The only thing that could improve it is the ability to directly integrate the current website without highlighting text. We recommend Voilà for professionals, content creators, and anyone who wants to optimize their AI-powered workflow without sacrificing privacy or functionality. | In our eyes, Grammarly is the best choice for anyone who wants to write professional articles or other things in English. Even though Grammarly has an expensice price tag, you can't get anything better on the market. We have been using Grammarly for a long time now. And even in the world of ChatGPT and other AI tools, Grammarly is just super handy and helpful. For us, the Premium plan is worth every penny. This only applies as long as you are in the English-speaking world. If you need other languages, we would recommend LanguageTool instead. |
