Most apps make you tap flashcards. Line makes you talk.
Line drops you into living story worlds where you learn a new language the way you actually learn one: by speaking it. Explore a map, walk into a café, a tavern, a train station or a space station, and have a real, out-loud conversation with characters who talk back in real time. No scripts to memorize. Just say something and see what happens.
SPEAK FROM DAY ONE
Have natural, real-time voice conversations with AI characters. Talk out loud, hear them respond in their own voice, and keep the conversation going as long as you like. It feels less like a lesson and more like being there.
LEARN INSIDE STORIES
Every conversation lives inside a scenario on an explorable map. Travel between locations, meet new characters, build relationships, and unlock new places as you go. Pick from ready-made scenarios across dozens of genres: adventure, romance, mystery, sci-fi, fantasy, noir, slice of life and more.
CREATE YOUR OWN WORLD
Want something specific? Build your own scenario from scratch. Choose the genre, setting, time period and tone, design a character, and guide the art style. Your imagination becomes your classroom.
GET BETTER, NOT JUST BUSY
At the end of every chat, get a clear grammar report so you know exactly what to work on. While you talk, tap for instant translations, romanization, and pronunciation playback, or use suggested responses when you're stuck. Help is always one tap away, never in your face.
MEET YOU AT YOUR LEVEL
From total beginner to fluent, Line adapts to you across five levels. Start with simple phrases and grow into smooth, confident, real conversations.
19 LANGUAGES TO LEARN
Arabic, Chinese, Dutch, English, French, German, Hindi, Indonesian, Italian, Japanese, Korean, Polish, Portuguese, Russian, Spanish, Swedish, Thai, Turkish and Vietnamese.
AN IMMERSIVE WORLD
Tilt your phone to look around hand-crafted scenes, with original art, music and sound that pull you in. Pick up any of your stories right where you left off and practice a little every day.
Stop studying a language. Start speaking one.
