Speak Spanish out loud in real situations. In a Conversation, Uncle Polar (an AI) plays a part and answers whatever you say, with a gentle correction when you slip. In the Role-play scenes you answer each line yourself, with a hint in English, and get a pronunciation rating for every go.
Uncle Polar is an AI. His replies are written by AI (OpenAI) and spoken by an AI voice (Microsoft Azure). He is friendly, speaks only Spanish and keeps to your level. What you say is turned into text so he can answer, and is not stored.
Hold the button (or Space) while you speak, then let go. A quick tap starts and a second tap stops. E shows the English of Uncle Polar's last line, H plays it again.
Fifteen short scenes, one for each topic in Phrases. Someone speaks to you; you answer with a phrase from that topic. You see what to say in English: say it in Spanish, or press Show me.
