Hey! I've struggled to learn a second language for a while. I didn't practice speaking and listening enough. I'm also a huge believer in personal privacy, so I built Koko to work fully offline, using only on-device AI. Therefore, your voice and info never leave your device.
Hey, love seeing this here! 👋 What inspired you to build this? Would love to hear the story behind it.
