What is fluentread?

FluentRead is an open-source browser extension for translating web pages, designed to give readers the feeling of reading in their native language. It works in Chrome, Edge, and Firefox and is available for free with no commercial strings attached. The extension supports more than 20 translation engines. These include traditional services like Microsoft Translator, Google Translate, and DeepL, as well as AI-based options such as OpenAI, DeepSeek, Kimi, and Ollama. Users can also configure a custom translation engine if they prefer something else. Several translation modes are available. One mode shows the original text and the translated text side by side on the same page, so readers can compare both without losing context. Another mode lets you highlight any text on a page and instantly see a translation, with a button to copy the result. A third mode translates the entire page at once through a floating button, without needing to reload. All settings and data are stored locally on the user's device rather than on any external server, which means nothing is sent anywhere beyond the translation engine the user chooses. The project describes itself as a more open alternative to Immersive Translate, another popular bilingual browser translation tool. It offers a high degree of customization to suit different reading scenarios. The README is written primarily in Chinese, and official documentation with detailed setup guides and tutorials is hosted at a separate website linked from the repository. FluentRead is a non-commercial, community-driven project. The source code is open and transparent, and installation is done through the standard extension stores for each browser.
