AI reading and math teacher that adapts to your child in real time
Ello listens as the child reads aloud, tracking correct letter sounds and words so the lesson can advance only when the child is genuinely ready.
Instead of a fixed path, the AI chooses what to work on next based on how the child performs in the current moment.
Children invent original illustrated stories about topics they love, turning their own interests into reading practice.
A curated collection of levelled books that grows with the child from their current level into more advanced material.
