What users praise
- • Voice-first practice removes the anxiety of finding a real conversation partner
- • Named tutors (Tama, Raven, Skye, Noah) with mild differentiation help personalise the sessions
- • Real-time corrections land inside the conversation without stopping the flow
- • Cross-session context memory means later dialogues start warmer than the first
What frustrates them

- • AI sometimes substitutes what it expected you said instead of registering your actual speech
- • European Portuguese users can't get the app to stop using Brazilian Portuguese
