Duomate: Language Exchange

Duomate is a language exchange app that turns your conversations into personalized study material.

Chat with native speakers who are learning your language while you learn theirs. As you talk, Duomate keeps track of the words and sentences used across the conversation, including what you read and what you write.

Then it brings that language back into your study.

No copying sentences into another app. No building decks by hand. Just talk, learn, and review the language that actually came up in your conversations.

LEARN FROM YOUR OWN CHATS

• Track vocabulary from messages you send and receive
• See words in the conversations where you used or encountered them
• Review vocabulary with built-in spaced repetition flashcards
• Study words from your chats alongside JLPT, HSK, and TOPIK vocabulary
• Translate any message instantly
• Transcribe voice messages so you can read what you heard
• Tap any message for vocabulary, grammar, and usage explanations
• Get help understanding mistakes and unfamiliar phrasing

CHAT WITH REAL PEOPLE

Find native speakers who are learning your language and practice together.

You help them with yours. They help you with theirs.

If you want more practice before talking with someone new, you can also chat with AI conversation partners. They use the same vocabulary tracking and study tools as your regular conversations.

STUDY THE LANGUAGE YOU ACTUALLY USE

Your study material does not have to come from generic vocabulary lists or someone else’s flashcard deck.

It can come directly from your own conversations.

Words you read.
Words you write.
Sentences you had to translate.
Phrases you want to remember.
Vocabulary you keep running into.

The more you use the language, the more useful your study material becomes.
