ONE Letter

With ONE Letter, you can get to know people all over the world—not through quick chats, but through real, digital “letters.” It's like a modern pen pal friendship. Can you get to know one person from every country in the world? There are only 195 :-) Each profile contains only the user's first name, spoken language, and country. When you're ready, you'll be randomly connected with another user from another country around the world. You can write letters to each other in your native language, but only one per day. Your letters will be automatically translated into your conversation partner's language – in addition to the original text. By limiting users to one letter per day, verifying users through World ID, and randomly pairing them up, authentic conversations between real people without filters are created. You can save the letters you receive in your inbox and see where they come from on a world map. After a few letters, you can save and continue friendships – or make new contacts. “ONE Letter” stands for deceleration, empathy, and genuine connection—a modern form of pen pal friendship in the digital age.
