From Brave 1.43.88, which was released earlier this month and is available for all users now, the browser started using Lingvanex to translate pages. When users visit a webpage in a foreign language (a language not installed on their device), Brave provides the option to translate it.
When users click on the menu, they have other options like picking a different target language, preferences to never or always translate the source language, and the option to never translate the site they’re currently visiting. They can also change the source language, if the browser gets it wrong.
The new translation feature is more private as it does not require connecting to Google servers. However, it still requires internet connectivity to be able to run the translation.
