Mossglen — AI Language Tutor for Web & Video

Read any page or YouTube video in the language you're learning — tap a word to translate and save it, review it later. 8 languages.

The AI agent for learning languages that makes the whole internet your textbook. Pip knows your level and remembers every word you’ve looked up. While you read the web or watch YouTube, it explains whenever you ask, saves your words and reminds you when to review. What Pip can do • Turn any article into a clean page in one click — Click “Read this page” and the ads and clutter are gone, leaving just the text. Tap a word for its meaning, turn on “Translation” to see it in your language, or have it read aloud. • YouTube captions, turned into a transcript you can tap — Open a video with captions and click “Open transcript”. The transcript follows the video, and tapping a line jumps there. • Saved words get marked on every site — Wherever you run into them later, they have an orange underline. When one is due, hover over it to review. • Pip remembers you — Where you get stuck, what you’re into, what you’ve corrected it on. Pip notes it all, so next time the explanation fits you better. Works in your browser and the AI you already use • Chrome side panel (While you read or watch) — Click Pip in the toolbar to open the side panel. Look up, save and review words without leaving the page. • ChatGPT, Claude and more (While you chat, phone included) — Say “help me review today’s words” and it already knows your words and your level. Requires an account. • Level test (Before you install anything) — No install, no sign-up. Take it right here on the website.
