FLAPS: Conversation instead of memorization, coaching instead of grading

FLAPS isn't a rigid grammar lecture — it's designed to help you pick up a language through short conversations with a new friend.

Real conversation with an AI coach

Exchange messages with an AI coach as if in a real situation, building sentences yourself. It's real speaking practice, not memorization.

Instant correction, on the spot

The moment you finish a sentence, you're told what felt off and how to fix it. Every mistake becomes material for the next sentence.

Choose your level & category

Learn your way with 10 difficulty levels and 10 categories — daily life, food, travel, shopping, business, health, hobbies, relationships, society, and technology.
