Fluent Reader

Fluent Reader is a free, open-source browser extension for bilingual translation. It is designed to give you a more natural, native-like reading experience on foreign-language pages. Instead of translating word by word, it uses AI to read the context and produce results that aim to be more accurate. It supports translation between multiple languages, and you can pick different translation engines and customize rules and shortcuts to match how you read. One of its selling points is privacy: all data is stored locally in your browser rather than being sent to and kept on a server. The extension works on mainstream browsers such as Chrome, Firefox, and Edge, and it is a non-commercial project, so the core features are free to use. It is aimed at students, researchers, and professionals who regularly read content in another language.

- Translate web pages in context for a smoother read.

- Switch between multiple languages and translation engines.

- Customize translation rules and keyboard shortcuts.

- Read papers, research sites, and emails in another language.

- Students reading papers and articles in a second language.

- Researchers scanning foreign-language research sites.

- Professionals handling emails and web pages in other languages.

Because it is a non-commercial, open-source project, the pace of updates and support can vary, so check the extension listing for current status before you depend on it for important work. Translation quality depends on the engine you choose and the language pair, and no machine translation is perfect, so read key passages carefully. Since data is stored locally, your settings and custom rules may not sync across devices or browsers, and you will need to set the extension up again on a new machine. If you rely on a specific translation engine, be aware that the engine's own terms and availability are outside the extension's control and can change over time. For anything sensitive, verify important wording rather than trusting a single pass.
