About

Personalang

Read full description

Personalang is a different way to learn a language: you talk. Meet Lucia โ€” a voice companion you can have real, spoken conversations with, in the language you're learning. She listens, replies in a natural voice, and gently corrects you as you go. And unlike a chatbot, she remembers your past conversations, so every session builds on the last. โ€ข Speak, don't tap. Real-time voice conversations โ€” the way you actually use a language. โ€ข A coach on the side. Gentle corrections, natural phrasing, and vocabulary as you talk. โ€ข She remembers you. Lucia recalls what you've talked about, your goals, and your name. โ€ข Short, daily sessions. Built around 15-minute conversations that fit real life. โ€ข Many languages. Practice in the language you're learning, with native-sounding voice. Your privacy comes first: audio recording is off by default and fully optional, and you can delete your account and everything in it at any time. Subscriptions unlock more daily conversation time. Start with a free trial. You can check https://personalang.com/terms for the Terms of Use.
