Features	9.2 The functional scope of GPT Reader is designed for a wide range of users and demonstrated many useful functions in the test. The voice quality is surprisingly good and offers a natural-sounding output. We particularly liked the comprehensive format support, which seamlessly processes everything from PDFs to web content. The control of the playback is also well implemented, making it easy to adjust the speed directly and individually. However, the function for downloading audio files stood out the most in the test. In theory, entire books can be converted and then downloaded as audio books. However, this was the only area where we had to make deductions, as the free ChatGPT version had limitations when processing longer texts or documents. We tried to convert a 300-page PDF and were able to process 22% of it, which corresponded to around 2 hours of audio. After this 22%, the free quota of requests on ChatGPT was reached, and the request was canceled.	8.5 Nowadays, websites request data through third parties. The local CDN emulation offered by Decentraleyes is a unique and effective feature that blocker competitors currently lack. This means that the same locally stored data is always sent directly to the websites before they can even request relevant private data. The extension is aware that this function is only an additional function and advertises it as being used in addition to regular ad blockers. The extension could be expanded here and offer these additional functions directly so that you have them all in one extension. Another advantage of the extension is that the code is completely open source and can be found on GitLab. This ensures transparency and trust.
Performance	8.3 The performance tests showed a mixed picture. For shorter texts and paragraphs, GPT Reader processes content quickly and delivers a smooth rendering. The application is fast and reliable for typical use cases such as articles or short documents. Here we tested self-written summaries for learning purposes. However, we encountered significant limitations with larger files, as it is not possible to complete processing due to the limited number of requests. The option of pausing and then resuming would help here. In addition, the process takes a very long time for larger files; the extension needed around 40 minutes for around 75 pages of a PDF. The limitations of the ChatGPT API particularly affect the processing of longer documents such as entire books. This is currently only possible with a premium version of ChatGPT.	9.3 The extension offers a noticeable improvement in page load times. We did not find any problems in our tests, but according to user reviews, there are occasional compatibility problems with certain websites. However, according to Decentraleyes, these are constantly being fixed by updates.
Design	9.0 The design of GPT Reader is clean and professional, with an intuitive layout that makes navigation effortless. The fact that there is even a dark as well as a light mode shows that the different user preferences have been taken into account. The controls are logically arranged and easily accessible. Even though the extension is designed for functionality, the design is not forgotten.	9.5 The design is intuitive and simple. This also includes the settings menu.
Value for Money	8.9 Currently, GPT Reader offers a very good price-performance ratio, as all functions are available completely free of charge. We found no hidden costs or unexpected limitations in the free version. The features should be sufficient for most users; the only thing to note is the limited number of requests per hour that ChatGPT allows. If you need to convert entire books into one, you will need a premium version of ChatGPT. It should also be mentioned that the extension already indicates that the download function may be offered in a paid version in the future, which could influence this rating in the future. At the moment, however, it is a very good offer in the text-to-speech sector.	9.5 The extension is completely free to use with optional donations. The price-performance ratio is therefore perfect, as functions that are not offered by other providers are made available here free of charge. Only the lack of further functions in the area of ad blocking results in deductions.
Ease of Use	8.7 In terms of user-friendliness, GPT Reader scores very well. Users of all technical levels should have little problem simply converting text to audio. The user interface is self-explanatory, and all functions are displayed immediately. The only negative point is that a separate ChatGPT registration is still required, and an error message appears if the ChatGPT requests are exceeded, which can lead to confusion.	9.9 The extension is characterized by its user-friendliness. Installation is very simple and you have the option of testing the function immediately on the website. When you open the website https://decentraleyes.org/test/, you are shown whether the function works and an example of what it looks like in the icon when data is blocked. The settings are also very well described so that even beginners should have no problems here. Advanced users can also read the complete documentation or the code on GitLab.
Security & Privacy	9.7 In our security analysis, GPT Reader showed a strong commitment to protecting user privacy. The extension only collects data from user-reported bugs and feedback. We appreciated the transparent privacy policy, where the user can read specific points.	9.2 The extension offers strong features in the area of data protection, so it goes without saying that it scores well in this area. The open-source code allows anyone to review the extension in detail. Only the lack of a proper privacy policy detracts from this for beginners, who can do little with the code. There is a privacy policy that states in one sentence that no data is collected. However, this should be a little more detailed.
Conclusion	GPT Reader is a promising text-to-speech extension based on ChatGPT voices. The easy-to-understand voices, combined with the fact that it is completely free, set it apart from conventional TTS tools. The extension can process various document formats. Both PDFs and copied web articles can be converted, but it has its limitations with longer texts. For example, a 300-page PDF was only partially converted in the text due to ChatGPT's limitations, which still resulted in about 2 hours of audio. The tool is very user-friendly and supports multiple languages. This extension is a must for anyone who wants to listen to texts.	Decentraleyes is a valuable tool for anyone who wants more privacy and faster browsing. With local CDN emulation, Decentraleyes has features that bring both security and performance benefits. While it currently excels in this one area, you need to be aware that websites also make adjustments and it won't always work 100% of the time, especially without further updates. Overall, Decentraleyes is a recommended choice for privacy-conscious users as an addition to the usual ad blockers.
