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.	9.0 LanguageTool offers a comprehensive set of features that go beyond basic grammar and spelling checks. It supports over 20 languages, making it a versatile tool for multilingual users. The advanced grammar checks are particularly impressive, catching complex issues that many other tools miss. Compared to competitors like Grammarly, LanguageTool holds its own with unique features like custom dictionaries and plagiarism detection.
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.	8.0 LanguageTool does a good job of spotting grammar and style issues. However, it can take a while to process longer texts, and sometimes, clicking on suggestions causes the page to jump to the top, which can be a bit frustrating.
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.	8.0 The design is clean and intuitive, making it easy for users to navigate and utilize the tool effectively. The browser integration is seamless, and the user interface is straightforward.
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 free version gives you the basics, but the premium version really shines with its advanced features. While Grammarly can be expensive, LanguageTool offers great value at a more affordable price. So, if you’re seeking a budget-friendly alternative to Grammarly, LanguageTool is a solid choice.
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.	9.0 LanguageTool is very user-friendly, with a minimal learning curve. Most users will find it easy to get started and make the most of its features right out of the box.
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.	9.5 LanguageTool takes privacy seriously. No account is required for basic features, and the tool ensures that user data is not sold or made public. This focus on privacy is a significant plus. LanguageTool states that it is GDPR compliant which makes it especially interesting for users in Europe.
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.	LanguageTool is a reliable and efficient writing assistant that supports multiple languages. Its advanced grammar and style checks make it a valuable tool for writers and professionals. While the premium version offers excellent features, the free version is somewhat limited. Overall, LanguageTool is a solid choice for anyone looking to improve their writing. Compared to Grammarly, LanguageTool holds its own, especially if you need to write in multiple languages. When it comes to writing in different languages, LanguageTool is the way to go. But if you’re only writing in English, Grammarly still delivers better results.
