Plans & top-up

Pick your monthly plan, apply any discount code, then stack one-off ACU packs whenever you need more. ACUs power the AI tutor, diagnostics, planner, interactive lessons, predictions, and other metered tools. Premium unlocks tools; usage is always metered (no unlimited AI).

Student plans — monthly only

Child Free is a separate student account — 100 ACUs every month, never added to paid plans. Paid plans add larger monthly allowances — from £5 Student Access through to £30 Student Max for daily heavy usage.

ACU packs — members only

Top-up packs are exclusive to monthly plan members. Your monthly top-up allowance matches your plan price — on the £10 plan you can top up up to £10 each month, on the £30 plan up to £30. Your plan is always the best ACUs-per-£ and the only way to unlock premium tools; packs are the extra fuel on top.

🌍 Fund a student — from anywhere in the world

Family abroad, diaspora, sponsors, community champions: buy a pack for any student and send them the gift code — the ACUs land in their wallet the moment they redeem it. No shared passwords, no access to their account, just funded learning. Gift codes are separate from the members-only rule: anyone can fund any student — free account or paid plan — and redeemed gifts never count against the student's own monthly top-up allowance. Gifts add study fuel; premium tools still come from the student's own plan.

Secure payments processed by Stripe. ACU packs are one-time payments. Every paid plan runs for exactly 30 days, then stops automatically — no auto-renewal, no lock-in and nothing to cancel. Renew whenever you choose.
Stripe checkout switches on per plan as billing keys are configured in the admin gateway — until then purchases credit your wallet directly so you can exercise the full flow.
