Linguist is a highly customizable solution for translation in the browser. By default, you may choose one of the embedded translators, you may even use an offline translator for privacy-sensitive texts.

Although Linguist does not limit you to embedded translators, you may integrate literally any third-party service with Linguist. ChatGPT, DeepL, Ollama, or anything else, you may integrate it all as a custom translator.

This feature is especially useful for those involved in research work and using Linguist intensively to translate content in many foreign languages, when standard translators may not provide good enough translation quality, or when translation must be fine-tuned.

Improved security​

Now custom translators executes in sandboxed context, so they no have access to addon API.

Users now may use custom translators with lower trust level. Custom translator still may sent requests to any domains from your browser, and still may mine on your hardware as any other software, but custom translator can't inspect content on pages and do other things that browser extensions do.

Manifest V3​

A chrome announced they will deprecate and disable extensions with manifest v2 soon. So Linguist migrate to manifest v3 on Chrome and stay on manifest v2 on Firefox.

Due to some limitations of Manifest V3, Linguist may not work on too old browsers like Chrome 109 and older.
