Plans and billing

What each plan includes, how one subscription covers RTL++ and Spice++, and how to change or cancel it.

The editor, simulators, builds and flashing are free on every plan. Paid plans add stronger assistant models and more credits, and one subscription covers both RTL++ and Spice++. Prices are on the pricing page.

Credits measure assistant usage, shared between the two products. One credit is a tenth of a cent of model cost, and stronger models use more per request. They renew each billing period and do not roll over.

Student pricing needs a verified school email address, such as one ending in .edu or .ac.uk.

Changing or cancelling

Use Manage billing in Settings. Upgrades apply straight away and are prorated. Downgrades and cancellations take effect at the end of the period you have paid for. Your projects stay with you on every plan.

Payments are processed by Stripe, which keeps your card details.
