Read at the speed of you.
Lumi is a free, voice-first AI reading tutor for K–3. She adapts in real time, remembers your child, and respects their privacy.
Why families choose Lumi
Lumi
Voice-first
Every instruction is spoken. Your child never needs to read to navigate. Lumi pre-caches audio so first-sound is under a second.
Lumi
Truly adaptive
A pacing engine watches the last few attempts and speeds up, slows down, scaffolds, or interleaves reviews — no two sessions look the same.
Lumi
Remembers your child
Tomorrow, Lumi greets your child by name and picks up exactly where they left off. Their progress lives in a private memory just for them.
