Learn anything,
one idea at a time.
Luna is a tutor you talk to. It finds where you're starting from, then guides you one question at a time, so the answer is yours.

How Luna works
Getting to know you
Exploring what you know
Finding a good next lesson
Start where you are
A short conversation, about five minutes, finds your starting point. Anything you already know is ticked off.
How many times bigger is 6 than 4?
One and a half times.
Work it out together
Luna asks before it tells, one idea at a time. Talk it through or write on the whiteboard, and every step stays yours.
See what clicked
Every session ends with up to three stars and the moments that mattered, so you know what to try next.
Keep your 5-day streak going
A quick session today keeps it alive.
Keep the streak going
Pick the days and time that suit you. Luna sends a gentle nudge, and every day you learn adds to your streak.
Stuck on homework?
Snap a photo or upload any question, in any subject. It lands on the whiteboard and Luna works through it with you.
