Features
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.

Tools

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.

AI Model

In summary, Sider offers almost all of the current possibilities of AI in one tool.

9.0

Voilà's features are impressively comprehensive and cover many areas, from simple AI chat to advanced content creation tools.
The library of pre-built expert prompts for various requirements is particularly valuable. This often allows you to get the right result without having to write anything yourself.

prompts

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.

Mail

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.

Summarize

Overall, the extension offers very powerful features, some of which are not even found in competitors' products.

8.8

The AI writing aid worked very well in the test with emails, customer responses, and short formats. We particularly liked the dynamic templates, which adapt according to user input. The extension can therefore be adapted for both commercial use, such as quickly replying to emails, and for everyday private use. From summaries to social media texts, this helped enormously in the test. In particular, learners such as students should have a special added value here, for example, through summaries that can be created quickly.

Summarize


Overall, AI Blaze already offers the possibility for almost endless possibilities; at most, there could be even more templates, as users may otherwise not exploit the full potential due to ignorance.

Performance
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.

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.

8.9

In our test, AI Blaze worked reliably on most websites and in various applications. The only thing that was immediately noticeable at the beginning was that the functions do not work in the Chrome Store, so websites may prevent access for the extension, but this did not otherwise occur in the test.

error

The text expansion works immediately, and the AI-controlled functions generally respond quickly, depending on the model selected. When using the most advanced AI models for complex tasks, there were occasional short delays, but these were minimal.

Design
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.

9.3

The user interface is clear and intuitive. The seamless integration with Gmail is particularly well done.
Dark mode and customizable designs improve the user experience. The extension does everything it can to avoid overwhelming users with information, allowing them to learn new areas of application step by step.

8.8

The clear, intuitive user interface should also make AI Blaze possible for private users who are not so tech-savvy. The integration into the sidebar is very well done and offers a seamless integration into the design of the browser.
There is little that can be customized visually, but this should hardly be necessary. Overall, the design focuses on functionality while maintaining an appealing appearance.

Value for Money
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.

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.

9.0

In this area, a clear distinction must be made between private and commercial users. For the private user, AI Blaze already offers enough functionality for most people in the free plan. Here we also appreciate the Academic Edition, which offers students and teachers extended, free access. The Pro plan could be too high for private users at $20/month with annual billing.

For businesses, however, AI Blaze's Pro plan offers exceptional value compared to similar productivity tools. The time savings alone can justify the investment for most users.

For those who want to work in teams, AI Blaze offers the Business plan for $24/user/month. This includes additional comprehensive functions for collaboration and improved communication processes.

Compared to alternatives, AI Blaze offers a competitive feature set at a reasonable price for businesses. The ROI is clear after just a few days of regular use, especially for those who frequently write similar messages.

Ease of Use
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.

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.

9.0

For basic functions such as using templates and simple shortcuts, AI Blaze is extremely straightforward. New users can start using the ready-made templates within minutes, and they are well-explained. If you don't want to use the predefined shortcuts, you can create your own commands immediately, which makes it easier to remember the shortcuts in everyday life.

We found the shortcuts intuitive and time-saving once you have memorized them. The search function makes it easy to find the right snippet quickly, even as the library grows. The advanced functions do require a certain amount of learning, but the basic functions are easily accessible straight away.

Security & Privacy
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.

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.

9.7

AI Blaze takes security very seriously and holds a SOC 2 certification, which confirms that a company has implemented appropriate controls and procedures for IT systems, data protection, and data security. The company's privacy policies are transparent from the user's perspective in terms of how data is handled, and no user data is sold to third parties.

The Business and Enterprise plans offer additional security features such as SAML SSO integration and audit logs.

Choosing between different AI models gives users more control over their data. The company is transparent about its use of cookies and analytics and provides clear options for managing settings. There is also the option to allow the extension only to use marked areas for answers, normally, the AI uses the entire website content to have a better data basis.

Conclusion

Sider is an AI tool that can significantly increase user productivity across multiple platforms. 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. In particular, the sometimes high prices will put normal users off. Overall, Sider is a valuable tool for anyone who wants to combine almost all the possibilities of AI in one tool and is willing to pay for it.

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.

AI Blaze shows that it is an impressive productivity tool that delivers on its promise of saving time and optimizing communication. The user interface is intuitive and well-designed, making it accessible even for those without experience with AI tools.

You can tell that companies in particular are also a target group. The ability to customize templates and train the AI to match your brand's voice is particularly valuable here.

While the free version is somewhat limited, the affordable pricing of the paid plans makes it accessible to businesses of all sizes. The time savings alone justify the investment for teams that frequently send similar messages or create repetitive content. Individuals, however, may find it too expensive.
