# Heartline

> Heartline is a cross-language dating and relationship app with real-time AI translation for text, voice, and video calls.

Heartline enables people who speak different languages to communicate naturally and build meaningful relationships. The app uses artificial intelligence to translate conversations in real time — so two people can speak, write, and see each other without sharing a language.
