Learn languages while watching YouTube videos with AI-powered term detection and explanations Learn English the way native speakers actually use it — through your day-to-day online content, starting with YouTube. Lingo is an AI-powered language-learning companion that lives where you already are. As you watch, Lingo reads the subtitles in real time and highlights expressions that textbooks don't teach: slang, idioms, phrasal verbs, cultural references, and the casual expressions Americans use every day. Each term comes with a clear definition and an example — right in the side panel, without pausing the video. Today Lingo works on YouTube; more platforms are coming. ═══ Who Lingo is for ═══ If you're a non-native English speaker with strong reading and writing (B2/C1, TOEFL 90+) but still get tripped up by: ▸ Phrasal verbs whose meaning isn't the sum of the parts ("pull in" ≠ pull + in) ▸ Slang from social media, TV, and movies ("no cap", "lit", "ghosting") ▸ Sarcastic intensifiers like sentence-final "much" ("obsessed much?") ▸ Cultural references and Americanisms ▸ Casual compound terms in conversation ("work-from-home", "post-breakup") Then Lingo is built for you. ═══ How it works ═══ 1. Open any YouTube video with English captions 2. Click the Lingo icon — the side panel opens 3. As you watch, Lingo detects terms worth learning and shows them on the side 4. Star the ones you want to keep — review them later in your dashboard That's it.
