Stuck on a physics problem?
Good.

NotClass doesn’t solve it for you. It figures out what you don’t understand yet, gives you three smaller problems that build the missing skills, and walks you through them — Socratically.

How it works

You bring the problem.
We build the path to understanding it.

Instead of solving your problem, NotClass identifies the specific concepts you’re missing and gives you three targeted sub-problems that build exactly those skills. A Socratic AI guides you through each one — asking questions, never explaining.

Your problem

“A 5 kg block is placed on a 30° ramp with friction coefficient 0.4. Does it slide?”

You’re stuck. You don’t know where to start.

NotClass identifies 3 missing skills
Sub-problem 1

How do you decompose gravity on a tilted surface?

Sub-problem 2

When does friction prevent motion vs. just slow it?

Sub-problem 3

What determines net force direction on an incline?

Socratic AI guides you through each one — never gives the answer

You learn because you need to know, not because it’s on the syllabus.

The difference

Every other tool

Solves it for you.

  • Upload a problem, get the solution
  • AI does the thinking, you copy the result
  • You pass the exam. You learned nothing.
  • Next semester: same gaps, harder problems
notclass

Teaches you to solve it yourself.

  • Finds the specific concepts you’re missing
  • 3 targeted sub-problems build exactly those skills
  • A Socratic AI guides you — questions only, no answers
  • You return to the original problem and do it yourself

Inside a sub-problem

It asks the questions
that make you discover
the physics yourself.

Each sub-problem comes with a Socratic AI that guides you without ever giving the answer. It asks questions. It surfaces contradictions. It puts you in situations where the concept becomes obvious.

The answer, once given, is immediately forgotten. The answer, once discovered, is never forgotten.

Sub-problem 1: Force decomposition
I don’t understand how to find the force component along the ramp.
notclassForget the ramp for a second. If you tilt a book and place a coin on it — which way does the coin want to slide?
Down the surface of the book, obviously.
notclassRight. Now — gravity pulls the coin straight down, but it slides along the surface. What does that tell you about the relationship between the gravitational force and the surface angle?
Oh — the component of gravity along the surface depends on the angle. The steeper the tilt, the more force pulls it down the slope.

Why this works

The gym for physics thinking.

01

Difficulty is the product

Every other edtech company tries to make learning easier. We make it productive. A gym that made exercise easy would be useless. A gym that makes exercise productive is invaluable. The sub-problems aren’t busy work — they’re carefully chosen so that solving them builds the exact muscle you’re missing.

02

No escape hatch

ChatGPT is a blank canvas. When you’re stuck at midnight, the temptation to say “just give me the answer” is enormous — and it will. NotClass won’t. It has no opinion about your grade. It has a strong opinion about your understanding. The only way through is thinking.

03

Understanding compounds

Once you truly understand forces on an incline — not memorize, understand — every problem involving ramps, friction, and force components becomes easier. Each concept you genuinely grasp makes the next one faster to learn. It’s compound interest for the mind.

Where this goes

Today: Socratic decomposition.
Tomorrow: a physics world.

Now

Bring a problem, get a path, build understanding

You’re stuck on a problem. NotClass decomposes it into sub-skills, walks you through each one Socratically, and sends you back to solve the original. Works today.

See the physics happen

AI-generated visualizations show what actually happens in each scenario. When your mental model disagrees with reality, you see exactly where and why. The surprise becomes visual.

Future

Build things in a physics world

A simulation where you have a mission — build a bridge, launch a rocket, design a circuit. The physics is real. When your thing breaks, you want to understand why. The breaking is the teaching.

Who this is for

The student who knows that getting the answer
isn’t the same as understanding it.

I can solve projectile problems, but I never know which equation to pick — I just try them all until one works.

AP Physics student

Surviving on pattern-matching. The decomposition shows them why the equation works, not just which one to use.

ChatGPT gives me the answer in 2 seconds. But I still can’t do it on the exam without it.

Engineering sophomore

They know the shortcut isn’t working. They need something that builds the skill, not bypasses it.

The professor derives everything from scratch, but I can’t picture what the math is actually describing.

University Physics 201

The sub-problems ground the abstraction in concrete scenarios they can reason about before touching equations.

I memorized F=ma but I don’t really get what happens when the angle changes or friction is involved.

First-year physics student

The formula is there. The intuition isn’t. That’s exactly what the Socratic decomposition builds.

“The first principle is that you must not fool yourself — and you are the easiest person to fool.”

Richard Feynman

Bring a problem you can’t solve.
Leave understanding why.

Free. No credit card. No sign-up wall.
Just you, the physics, and a Socratic AI that won’t give you the answer.
