Learning C1 German with AI

At C1 the AI partner discusses complex topics with you, explains fine distinctions of meaning, and points out where your German sounds translated. The AI also explains any wrong answer in a lesson, in plain English. It's included free, with a daily allowance; like any AI it can make mistakes, so the lessons remain the reference.
