Bonjour !
Introducing Osmo

The language companion
that actually feels
like a friend.

Osmo speaks French with you — not at you. No lessons, no streaks, no grammar tables. Just a warm, curious companion who learns what you love and slowly draws you into the language.

Free to join. No spam, ever.

Wonderful — you're on the list. Osmo can't wait to meet you.

Your data. Your phone. Full stop.

Osmo only knows
what you tell it.

Every other language app builds a profile on you — your habits, your location, your listening patterns. Osmo doesn't. Your memories, your conversations, your vocabulary never leave your phone.

Delete the app and everything is gone. No server record. No backup. No trace you ever existed.

Stored on your device only

Conversations, memories, vocabulary — all local. Never uploaded. Never synced to a server.

Osmo only knows what you share

It learns your interests because you told it — not because it tracked you. Nothing inferred. Nothing assumed.

No ads. No data selling. Ever.

Osmo makes money from your subscription. Not from you. One price, nothing hidden.

How it works

No app has ever
worked quite like this.

Osmo isn't a lesson. It's a conversation. You talk, Osmo listens, responds in French, and gently draws more of the language out of you — every day.

01

You speak. Osmo listens.

Open the app and just talk — about your morning, your commute, whatever's on your mind. Osmo responds in a warm mix of French and English calibrated exactly to where you are.

02

French grows into your life.

No curriculum. No schedule. Osmo finds moments in your day and French begins to feel natural, not studied.

03

Osmo grows with you.

As your vocabulary expands, Osmo physically grows on screen. No points, no streaks. Just a quiet, visible sign that something real is happening.

04

Everything stays on your phone.

Osmo remembers your interests, your dog's name, your dream trip — all on your device only. Delete the app and it's gone. No server profiles, ever.

Five languages. One companion.

Same Osmo.
Five different worlds.

Switch languages and the world around Osmo shifts entirely — different palette, different cultural personality, different voice. Like visiting the same friend in five countries.

The story

Built for people who've
already quit a language app.

Every language app is built on guilt. Streaks you dare not break. Lessons that feel like homework. The crushing reminder that you haven't practised in three days.

Osmo is the opposite. No curriculum. No points. No pressure. Just a warm companion who learns what you love — and slowly, naturally, draws you into the language.

The name says it all: you don't study with Osmo. You absorb the language by osmosis — the way you'd pick up French living next door to a friend who happened to speak it.
Your memories. Your device. Always.
No ads. No tracking. No profiles.
Delete the app — it's all gone.
