A messenger that teaches you

Learn a language by texting your friends.

Every word you learn swaps itself into your group chats. You see it every day, in real conversations, with the people you actually want to talk to.

✓No drills✓No strangers✓Just your people

One group chat. One new language.

Sound familiar?

You’ve done the lessons. You still can’t reply.

500

A 500-day streak, and you still freeze

The streak grew. The conversation never started. You got good at keeping a number alive.

Sentences you’d never say

Drills teach words from a textbook, not the ones your friends and family actually use.

Hi! Where are you from?

Strangers who stop replying

Language exchange apps mean starting over with someone new, again and again.

You don’t need more lessons. You need the language where your life already happens — in your chats. That’s Tokki.

How it works

Three steps. Zero study sessions.

There is no lesson to open. The lesson is the conversation you were going to have anyway.

Start a chat with your people

Friends, a partner, family — or join a public group for your language if you’d rather start there.

Tap any word to learn it

Tokki looks up the translation. Save it and it joins that chat’s vocabulary.

It swaps into every message

From then on the word arrives in the language you’re learning. You read it every day, in context, without trying.

Watch one sentence change over six months

Nothing here is a lesson. It is the same message, written the same way, arriving more and more in the language you are learning.

Day 1You make a group and pick a language. Everything is still in yours.
Week 2A few words are in. They start swapping themselves into messages.
Month 2Half the sentence arrives in German and you read it without stopping.
Month 6You are reading your friends in a language you never sat down to study.
What are you doing today? I’m going to the library.
Day 1 · your language, every word
What are you doing heute? I’m going to the Bibliothek.
Week 2 · two words you added yourself
Was machst you heute? Ich gehe to die Bibliothek.
Month 2 · more of it lands in German
Was machst du heute? Ich gehe in die Bibliothek.
Month 6 · and you understood it on the way past

Why it sticks

And one day, you just… answer.

Most people learn a language for someone. Tokki puts your words into the chats with those people — so when your partner’s mum writes in German, you already know most of it. And you can write back.

Frequently asked questions

How does Tokki work?

You chat with friends as you normally would, in your own language. You pick a language to learn and add words to that chat’s vocabulary. From then on, those words are swapped into everyone’s messages automatically. Tap any swapped word to see the original and hear it pronounced. As your vocabulary grows, more of each message arrives in the language you are learning.

How do words get added?

Tap a word inside any message and Tokki looks up the translation for you. Tap a second word to take the whole phrase. You confirm which language each side is in — and flip it if the guess is backwards — and the word joins the chat’s vocabulary.

Do I need someone to practise with?

No. You can join a public topic group and talk with other people learning the same language. Tokki works with a partner, a group of friends, or on your own in a public group.

What happens if I miss a day?

Your streak starts again and Tokki takes a nap until you’re back. You get at most one reminder a day, and you can turn reminders off.

Is Tokki free?

Yes. Chatting, vocabulary, pronunciation, quizzes and streaks are free, on iPhone, Android and the web.

Which languages can I learn with Tokki?

German, Spanish, French, Italian, Portuguese, Japanese, Korean, Chinese, Russian, Arabic, Dutch, Swedish, Polish, Turkish and English. You choose a language per chat, so different conversations can teach different languages at the same time.

I teach a class. Is Tokki for me?

Yes — teachers run groups with activities that mark themselves. See Tokki for teachers.
