Physics homework help from forces to circuits
No subscription.
Units, forces, energy, electricity: the tutor untangles what the question is actually asking, helps pick the right formula, and checks each step of the calculation. For olympiad-level problems, escalate the same conversation to a frontier reasoning model.

Free study tutor: uses none of your balance. Photos of worksheets work too.
The rules are locked in, not just suggested
The tutor's no-answers rules are built into the tool on our servers. A student can't edit them, switch them off, or talk the AI out of them. Rules you pin for your own child lock in exactly the same way.
- No final answers: for graded exercises the tutor explains the method, asks questions back and gives hints. It will not write the essay or state the end result.
- Work first: the Check-my-work tool asks for your child's own attempt before saying anything, then points at the first mistake only, with a hint to fix it themselves.
- Enforced on every message: our servers attach the rules to each message in the conversation, on the free model and on every stronger model your child switches to.
- Your rules get the last word: anything you pin for your child, and family-safe mode, is applied after all other instructions. It always wins, and only you can change it.
Built for the whole family, not another subscription
One top-up from $5 covers the household: free tutors for everyday physicshomework, and the world's strongest models (GPT-5.6, Claude, Gemini) one click away in the same conversation when it gets really hard (typically a few cents per question). Each child gets a subaccount with a spending cap, family-safe mode and rules you pin: visible to them, changeable only by you.
Questions parents ask
Is it free?
The study tools are free to use and never spend your balance, a one-time top-up from $5 unlocks the account. Stronger models bill per question, typically a few cents. No subscription, and credit never expires.
Isn't this just cheating?
The tools are built to teach, not to do the work: they explain methods, ask questions back and give hints, and they refuse to hand over final answers to graded work or write essays. That rule is pinned into the tool itself.
How do parents stay in control?
Create a subaccount per child on your balance: spending caps, family-safe mode, feature switches and pinned rules the child can see but not change.
What about hard physics problems the free model can't do?
That's the built-in escalation path: switch the same conversation to GPT-5.6, Claude or Gemini in the model picker. A typical hard problem costs a few cents, no subscription.
Sign up, top up from $5 once, and the study tools are free from then on.
