Built for the parent who reads the fine print.
Lumi is a free, voice-first reading tutor for kids ages 5–9. Designed for one child at a time — yours. Here is how it works, what is safe, and how to start in under a minute.
Six minutes. Six task types. Paced for the child.
Tap the firefly.
Your child opens Lumi and taps Lumi to start the session.
Lumi speaks.
Every instruction is voiced. Your child never has to read to navigate.
Six task types.
Tap-the-sound, tap-the-letter, build-the-word, sound-match, heart-word flash, sequence-two.
Lumi adapts.
Fast-forward on streaks, scaffold on misses, interleave reviews, graceful stop.
Tomorrow.
Lumi greets your child by name and references yesterday's work.
