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.

Ad Blocker:

In our tests, ad banners and ad videos were blocked on all websites, including YouTube and Twitch. Blocked ads also include social media widgets and pop-ups, among other things.

Customizable

AdGuard Adblocker offers the option of activating or deactivating all functions yourself.
It also offers an allow list and user-defined rules. This means that you can make adjustments to the rules or allow advertising on certain websites that you want to support.

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.

9.0

A recent user complained in a review that it had YouTube problems that affected the performance and speed of the website. In our test, we did not notice any performance problems. The extension generally works quickly and reliably. There are also regular updates, so the problem may already have been solved.

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.

9.2

The design is very clear and well-organized. The display of the settings is significant for adblockers. Here, great importance has been attached to user-friendliness and highlighting the customizable settings.

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.

future premium function

At the moment, however, it is a very good offer in the text-to-speech sector.

9.2

The free browser extension offers numerous functions that worked perfectly in the test. Compared to competitors, you get many functions here that others offer for a fee.
If further functions are required that can also be used outside the web browser, AdGuard Adblocker also offers an app that is subject to a charge. We consider the current lifetime prices to be fair for the services offered.

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.

9.5

Installation is quick and easy. What impressed us in comparison to other competitors was that AdGuard Adblocker clearly shows which functions it offers and explains them in the introduction, and you can activate them directly if you wish. The extension therefore attaches great importance to ensuring that every user recognizes and uses the options. With competitors, some functions were somewhat hidden in the settings.

Configure
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.

8.0

Strong privacy protection by preventing tracking. Also features malware detection and blocking, although public complaints could raise concerns.
Overall, AdGuard provides transparency in its privacy policy and limits data collection. Some practices, such as filing public complaints and reviewing website visits, should be critically questioned.

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.

AdGuard Adblocker is, in our opinion, a very good ad-blocking tool compared to its competitors, offering a range of features in the free extension that you often have to pay for. In our test, all ads were blocked. Other ad blockers currently fail because of YouTube's advertising videos, but AdGuard currently seems to have this fully under control. Overall, it is the choice for a free browser extension with many features.

Finally, we would like to point out that our test is about the browser extension. If you work in different browsers and don't want to install a new extension in each one, or if you work a lot in apps that carry out advertising and tracking, AdGuard Adblocker offers an app for comprehensive security outside the browser.

The AdGuard app allows you to block advertising in other apps outside of your web browser, for example, and keep your data secure. Here is an overview of the additional functions:

Comparison

Currently, you have the opportunity to purchase the app as a lifetime plan. Here you can decide whether the app should be installed on 3 or 9 devices.
