Know what your child actually understands
Free AI apps will happily tutor your child and tell you nothing. ChapterLens has them explain each concept in their own words, checks the reasoning, and shows you exactly where they stand.
In pilot with early families — now inviting school pilots. Takes about a minute to set up.
What you get that free AI doesn't give you
The honest answer to “how is my child really doing?”

Open it any time and see what your child has actually mastered, what they're still working through, and the one concept that needs you — without asking them, and without taking their word for it.

A quick walk through what your child actually does.
How we know
Your child explains it. Our AI checks the reasoning.
“Mastered” is only worth reading if a real check sits behind it. So your child answers in their own words, and the reasoning is marked line by line — which is where every number on your dashboard comes from.
Why does ice float on water?
Aarav, Class 8 — in his own words
Because when water freezes the molecules spread out and lock into a structure, so the same water takes up more space. That makes ice less dense than water, so it floats.
Every concept, animated
Short animated videos break down each concept visually, so kids grasp it before they're ever quizzed on it.

The gap most apps miss
Class 8 today. But the gap might be Class 6.
A concept that builds on an earlier one carries that link inside the lesson — named, labelled with its grade, one tap away.
So when something isn't landing, your child doesn't have to guess what to go back to. Those links reach down to Grade 5, even though we teach from Grade 6.

Grade 6Rewards you set, earned by what they've mastered
You choose the reward. It unlocks on concepts your child has genuinely mastered — never on hours logged. And your child can counter-propose, so the deal gets agreed rather than imposed. Here's what parents can set up:
₹200 pocket money
Master the Integers chapter
Movie night pick
Master the Light chapter
Saturday out with Dad
Master 5 Science concepts
Pizza night choice
Master 3 concepts in Fractions
Won't this teach my child to expect a reward for everything?
It's a fair worry. Rewards tend to backfire when they're attached to things a child already enjoys — the risk is real. That's why ChapterLens ties them to mastery rather than time spent, and why you set them, not us: they stay part of how your family already works, instead of a points system we invented for your child to chase.

Study time that stays study time
You set a four-digit PIN. While your child is studying, their phone stays on Chapter Lens — slipping out to another app or signing out asks for your PIN, not theirs. No arguments about the phone, because the phone isn't the argument any more.

Why parents are joining
A free AI tutor tells you nothing
It will help your child for an hour and report to no one. ChapterLens shows you what they understood — and what they did not.
Mastery you can check, not take on trust
Kids explain answers in their own words, and the reasoning is marked — so "mastered" is a finding, not a feeling.
Finds the gap under the gap
Every concept links back to the one it's built on, down to Grade 5 — so a Class 8 struggle traces to its real cause.
Start with one concept
Let your child explain one thing they were taught this week — and see what the marking tells you about how well it actually landed.
