In-tab AI translation and language-learning companion for your browser
Translate without opening a separate translation tab, keeping you inside the page or site you are currently working in.
The extension pairs translation with study-oriented assistance, so looking up a phrase and practicing a language happen in the same flow.
Runs as a standard Chrome add-on that installs, updates, and is managed through the browser's own extension system.
The package is only about 23 KB, so it adds negligible weight to the browser and installs almost instantly.
