Master languages naturally across the web. Instant AI translations, context analysis, and examples with just one click. Lanmma: Master Languages Naturally Across the Web

Lanmma is an AI-powered language learning extension designed to turn the entire web—and YouTube—into an immersive classroom. Instead of switching tabs to look up words in external dictionaries, Lanmma allows you to interact with YouTube captions or select text on any webpage to gain a deep, contextual understanding of any language instantly.

Whether you are watching videos, reading news, or studying articles, Lanmma helps you bridge the gap between "studying" a language and actually "absorbing" it.

Core Features

Universal Text Selection: Don't limit your learning to videos! Select any text on any webpage to instantly trigger Lanmma's AI analysis. Learn vocabulary directly from the articles, blogs, and tweets you read every day. Deep Dive Analysis: Go beyond single words. Lanmma can perform a "Deep Dive" to analyze entire paragraphs, explaining complex sentence structures, idioms, and overall meaning. Contextual AI Word Analysis: Powered by Google Gemini and Groq AI, Lanmma analyzes the specific sentence you are reading or watching. It explains how a word is used in that exact context, including its grammatical nuances and cultural register. Vocabulary Library: Save any word or phrase with a single click. Your personal library automatically stores the original source URL, video timestamps, and the exact contextual fragment, allowing you to revisit the context whenever you need a refresher. Premium Speech Synthesis: Listen to accurate, high-quality pronunciations. Lanmma integrates with industry-leading TTS engines like ElevenLabs and Google Translate to ensure you hear the correct native-level intonation. Interactive UI & Dark Mode: A seamless, high-performance UI that overlays beautifully on YouTube and other sites. It supports auto-detection of languages, respects bidirectional text (RTL/LTR), and features a sleek, YouTube-accurate Dark Mode. Privacy and Transparency Lanmma is built with a "Privacy First" philosophy.
