Bridge the gap between app practice and real-world fluency.
Tired of long app streaks that leave you frozen when ordering food, talking to a landlord or chatting with peers abroad? Fluo is an adaptive, AI-powered language platform that tailors every lesson to your real-life goals.
Learn for free

Learn to engage in real conversations, not with word banks.
Active production over word banks
Real conversations don't hand you a list of words to pick from. Fluo trains active recall so you can pull vocabulary and grammar naturally mid-conversation.
Your goals, not a fixed path
Skip rigid paths full of animals and colours you don't need yet. Learn the language for the situations you actually face.
Confidence before it counts
Rehearse high-stakes moments in low-stakes sessions, so you don't freeze up in the real thing.
A curriculum shaped around your reason for learning.
Share your objective — like “meeting new friends in Barcelona” or “housing administration in Berlin” — and Fluo builds a tailored curriculum around it.
- Chapters and lessons generated from your goal
- Synthesis lessons that bring earlier vocabulary into new contexts
- Interactive activities in every lesson

Voice practice with AI that feels like a native conversation.
Practise speaking through real-time audio scenarios with the Fluo Tutor or dynamic AI personas — like a cautious landlord or a new friend at university — and build confidence in a low-stakes environment.
- Real-time voice conversations
- Pronunciation guidance and corrections
- Personas matched to your scenarios
- Picks up where your last session left off

A tutor that remembers how you learn.
Fluo builds a digital twin of your learning profile — your goals, your progress and the mistakes you keep making — so every lesson builds on the last.
Digital twin
Fluo remembers your context and progress, and anchors new concepts in what you already know.
Friction Log
Every corrected mistake is logged, so recurring slip-ups get targeted practice.
Proactive guidance
Fluo reminds you of your usual mistakes in the moment — before you make them again.
Corrections that explain
See what you said, the fix, and why it's right.

Intelligent capturing of your key phrases and learning points.
Every lesson comes with a notebook that fills itself in — and stays yours.
- Pre-filled key phrases with audio
- New vocabulary extracted after each session
- AI-summarised notes that preserve your personal edits
