School practice that knows why your child got it wrong.
Math, reading, spelling, writing, science, history, geography, art, music and health, for ages 6 to 13. When an answer is wrong, Smart Tutor works out the slip or mix-up behind it, explains it, and brings the skill back before it is forgotten.
Start practicing What is Smart Tutor?
No sign-up. Works offline. No AI talks to your child.
When your child gets one wrong, it says why.
"Wrong, try again" does not help a child who used the wrong method or holds a mixed-up idea. Smart Tutor knows the common slips and mix-ups children have in each subject, so it can name the one your child made and show how to fix it.
If they are still stuck, help comes in small steps: a hint, then a worked example of a similar question, then the question done together, one step at a time. Your child does each step.
62 − 15 = ?
Your answer 53
In one column you took the top from the bottom. Always take the bottom from the top, and trade a ten when the top is too small.

The same in every subject
Spelling
Spell the word: I am ___ to win.
Your answer hopeing
Not yet. When a word ends in a silent e, drop the e before you add -ing.
Science
Why is it warmer in summer?
Your answer Earth is closer to the Sun
Not yet. Earth is a little farther from the Sun in July. Summer comes from Earth's tilt: sunlight hits our part of Earth more directly.
Geography
What is the capital of New York State?
Your answer New York City
Not yet. New York City is the biggest city, but the capital is a smaller city. Many states choose a capital that is not their biggest city.
A practice day
- Pick a subject. Each subject has its own path, matched to your child's school year. A short math check finds where to start in math.
- About ten questions a day. At the right level, with stories to read, words to hear and spell, and pictures to touch in math.
- Skills come back to stay. A skill your child has learned comes back after 1, 3, 7, 21 and 60 days, so it sticks.
It grows up with your child.
There are three looks to choose from. A grown-up picks one in settings, and can change it any time. Every subject has its own village to build.
Why not just use an AI chatbot?
Chatbots are good at many things. For a child learning, we chose something else, on purpose.
It is never confidently wrong.
A chatbot can give a wrong answer and sound sure. Smart Tutor checks math with exact rules, and every other answer against an answer key we wrote and tested.
Your child does the thinking.
In a chat it is easy to ask for the answer. Here, help comes in small steps, and your child fills in each one.
Nothing leaves your device.
No account, no chat logs, no recordings, no ads, no trackers. Names, answers and progress stay in this browser.
It works anywhere.
On an old tablet, in the car, with no internet. Once it has loaded, it keeps working offline.
Where we do use AI
We use AI behind the scenes, while we build Smart Tutor. It helps us write lessons, stories and hints, list the slips and mix-ups children often have, and check our work, so we can cover every subject, faster.
Everything it helps make is checked before it goes out. Our tests make about 200,000 practice questions and check every answer, hint and step, and every fact question is checked against trusted sources.
No AI is inside the app. Nothing AI ever talks to your child, sees their answers, or learns from them. In this day and age, we think children's privacy is worth protecting.
For grown-ups
- See the mistakes your child makes, in plain words, with a tip for each.
- Print practice sheets with an answer key that explains the common wrong answers.
- Add brothers, sisters, or a whole class on one device.
- Save a backup file to move progress to another device.
