Eight to choose from, switchable at any time, with data tracked separately per language.

Open an article and click the icon

In the reading view: tap words to save them, listen sentence by sentence, read side by side, and ask Pip anything.

Before you install

Desktop Chrome or Edge. No extra models or fonts to download.

Works without an account: reading, lookup, narration and a locally stored word list.

It does not log every page you browse — only the article you open on purpose.

Install questions

Click the puzzle icon at the top right of the browser, find Mossglen in the list, and click the pin beside it.

Unzip it, open chrome://extensions, turn on Developer mode at the top right, click "Load unpacked" and pick the unzipped folder. Edge is the same at edge://extensions.

Either the page has no extractable article (image-only or login-walled content), or its language is not your current target language.

Not yet. Today we ship for Chromium browsers only (Chrome, Edge, Brave, Arc).
