Two simple options for two kinds of learner

Each question a student sends Ollie, typed or spoken, is one message. Ollie's own automatic hints in a lesson or lab are not counted, and a question Ollie could not answer is given back. Messages refresh every month.

Explore and the Course Creator turn any topic into a short course. Starting a new course uses 5 credits, and Ollie writes the whole course for them: every lesson, quiz and practice. Joining a course someone else already made is free. A topic Ollie turns away, or a course that could not be fully written, costs nothing: its credits come back.

Either the student or a parent. A student aged 13 or older can choose and pay for a plan from their own account, after confirming they are 18 or have a parent's permission. A parent or guardian can also choose a child's plan from their family account, and a student can ask a parent for a bigger plan with one button. Children under 13 have accounts a parent creates, so only a parent chooses their plan and they never see a payment form.

Yes. A yearly plan is twelve months of the same monthly allowance for the price of ten, and the messages and credits refresh on the same day each month.

Any time, from the Plans page. Moving up takes effect at once and charges only the difference. Moving down also takes effect at once, and the unused part of what you paid becomes credit on your next bill. Cancelling keeps the current plan until the end of the period already paid for. Course creator credit packs are one-off purchases with no subscription.

No. Credits stay on the account until they are used. A new course creator account starts with one free course; students on the Free plan get one new course every month instead.

Payments are processed by Stripe. OHM never sees or stores a full card number; it keeps only what it needs to know which plan an account has. Prices are in US dollars.

One plan for a parent's children. Each child gets everything in OHM Pro: 300 questions to Ollie and 20 new courses a month, and homework photo help. Every child has their own allowance, progress and reports. The one time children share is after a seat changes hands mid-month: what the child before used still counts toward the family's total until the month refills.

$15 a month or $150 a year covers up to 2 children. Each child from the 3rd adds $5 a month or $50 a year, up to 8 children: $20 a month for 3 children, $45 for 8.

Adding a child into a seat you already pay for costs nothing. A child beyond those seats is charged for the rest of the current month or year, and you see the amount before you confirm. Removing a child isn't refunded, but their seat stays paid and open for another child until the next bill, which then drops. What they used that month still counts toward the family's total, so a child who takes their seat before it refills shares what's left. A child who leaves keeps all their learning on the Free plan.

The parent who pays for it chooses which of their children are in it, from their Plans page. A child can be in one Family Pro at a time. A learner who made their own account can leave a seat themselves; a child a parent created can't.

Every child keeps all their lessons, progress, reports, certificates and courses, and moves to the Free plan. Nothing is deleted.
