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.

7.0

In our tests, the functions of Tab Notes proved to be ideal for quickly creating notes directly in the browser. If you need to develop ideas or jot down information quickly while browsing, you don't have to jump back and forth between apps.

notes

Notes can be synchronized across different devices with GitHub gists to keep everything in one place.

There is a dark and light mode function, but we would like to see more customization options here.

The option to access your notes offline can also be an advantage. This also includes the export function, where the notes are exported as a text file.

txt

Functions such as “Customize: Edit font, font size and more” and “Styled text: Make your text bold, italicized or underlined.” are listed as features on Github. These were not found in our tests in the extension on Chrome and Firefox. We feel that this function is important to be able to structure the notes a little, which would further improve the extension.

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.

7.5

In terms of performance, Tab Notes is fast and responsive. It doesn't take up any resources, so your browser runs smoothly. Only the settings selection page didn't work for us. Selected options could not be saved here.

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.

8.0

The user interface is very clear and easy to use. We had no problems finding my way around and using the tool. In our test, we noticed that we would like to see a few more themes and color options. The layout is intentionally simple to minimize distractions, but it would be important to have different layout options for the font.

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.

8.0

The price-performance ratio of Tab Notes is fine. The extension is completely free. Compared to other free tools, however, the functions and customization options are somewhat limited. However, if you are looking for a simple extension for short notes without any frills, you will find it here.

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.

8.2

We found Tab Notes to be super easy to use. Installation and subsequent navigation is a breeze, and you can get started straight away without needing a manual. Due to the small number of functions, it is suitable for anyone, no matter how tech-savvy they are, to take simple notes. Only the non-functioning of the settings page can confuse new users.

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.

8.5

Tab Notes uses standard encryption to protect your data. Advanced security options are not available. The privacy policy is also kept very simple and does not provide detailed information about data management. In general, the basic security and data protection guidelines are adhered to, but in our opinion they could be presented in more detail.

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.

Tab Notes is a good tool for anyone who wants to write down ideas as a note as quickly as possible without having to sort them out too much.

Its intuitive and simple design increases productivity by reducing distractions when you just want to make a quick note. It could still be improved in areas such as customization and the number of features.

Overall, it's worth considering for anyone who wants to quickly collect notes and possibly sort them into another application later.
