A few good places to start
Learning with Lalu
Can Lalu answer any question?
No. Lalu uses the authored Mycode curriculum. Arbitrary AI conversations would require connecting an AI service; the learning experience does not need one.
Can I hear Lalu speak?
Yes, if your browser provides speech synthesis. Enable speech in Settings, select an available device voice, and use the speaker beside an explanation.
Where is my learning progress saved?
On this browser and device only. Mycode does not claim cloud synchronization.
