What is Lingle
Real-time voice lessons with a tutor that plans the session, tracks every error, adapts difficulty in the moment, and builds a model of how you learn.
Guided
The tutor plans the lesson, runs the activities, and leads you through it — like sitting across from a real teacher.
Adaptive
The tutor reacts to you in the moment — explaining, jotting notes, and sketching on the whiteboard right when it helps.
Personalized
Every lesson follows a plan we built around your goals — what you want to say and where you’re headed.
Flexible
Start any time. No booking, no scheduling — your tutor is ready the moment you are.
“Now let's roleplay — order a coffee in French.”
How it works
Join a live voice call and just speak — the tutor listens and replies like a real conversation.
“Tell me about your weekend.”
It corrects your mistakes in the moment and writes new words and grammar to a shared whiteboard.
You said
Yo tiene un perro
An algorithm plans every lesson and charts your path — so each session moves you measurably closer to your goal.
Your progress
B1 → B2Everything in one place
Lessons are planned and sequenced like a great tutor would — warm-up, focused practice, recap — not random chit-chat.
Past tense in conversation
Use 〜なければならない naturally in speech
Warm-up
Focused practice
Name a topic and Lingle writes a focused mini-course — clear explanations, real examples, the works.
The passé composé
Form it with avoir or être plus the past participle.
manger → j’ai mangé — “I ate.”
It remembers your goals, your slip-ups, and the little facts you mention — and brings them back exactly when they matter.
What the tutor remembers
The words you learn and actually use in lessons turn into spaced-repetition flashcards, automatically.
