The Slowletter approach
Tandem is optimized for practice sessions. Slowletter is optimized for connection. You are matched by interests, so exchanges tend to start as friendships rather than lessons.
No pressure to reply instantly. Letters give you time to think, write well, and actually enjoy the exchange, which is also great for learning a language.
Instead of searching by language and messaging strangers, you write about your interests and Slowletter finds someone who shares them.
Your identity is revealed only after mutual acceptance. You choose who gets to know more about you.
Slowletter is free to join and free to use core features, with no premium gate between you and your pen pal.
After enough letters, real-time chat unlocks, so a good connection can grow into an easy, ongoing conversation.
