Language Lab
Pick the language you're learning and the one you speak, then just talk. Co-Star teaches, asks, listens and corrects out loud while phrases, words, grammar and feedback appear on their own. Say “repeat”, “slower”, “what does that mean?” or “hint” anytime.
Live Labs require a current Plus or Pro membership. Explore the Labs, then choose a plan to start practicing.
Greetings and introductions

Say “repeat”, “slower”, “what does that mean?” or “hint” anytime.

Once you start, everything happens by voice; there's nothing to click. Use headphones so Co-Star doesn't hear itself. Your voice goes to Co-Star live. Audio is not saved; your transcript, actions and summary are saved to your account. Co-Star keeps a learning record for each language (words, mistakes and lesson notes) so every lesson picks up where the last one ended. It's part of your data export, and you can forget it anytime.
