Your chats, slowly becoming another language
Tokki is a messenger where learned words replace themselves in your conversations. You chat. Your messages evolve. You learn without trying.
Just chatting
Everything's in your language. You create a group, pick a target language, and start talking.
First words appear
You learn a few words and add them. They start replacing themselves in everyone's messages.

Frequently asked questions
How does Tokki work?
You chat with friends in a group 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.
Is Tokki free?
Yes. Chatting, vocabulary, pronunciation and quizzes are free, on both iPhone and Android.
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.
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 study partner, a group of friends, or on your own in a public group.
How is Tokki different from Duolingo or Babbel?
Those apps give you exercises built from a fixed curriculum. Tokki has no curriculum: the words you learn come out of conversations you were going to have anyway, and the quizzes are generated from that vocabulary. You are not adding study time to your day, you are learning inside the messaging you already do.
Does Tokki work offline?
You need a connection to send and receive messages and to hear native pronunciation. Vocabulary you have already loaded stays visible.
