Try Business for 30 daysPro is free for students and teaching staff. It offers the same features as Pro: all printouts and files, plus models in your account. Each output bears the note ‘not for commercial use’. Company details in the header belong to the company account and are not included here.
Get started with university emailWhen you sign up, you set up your payment method with Stripe; no payment will be taken for the first thirty days. The tier is activated immediately. Seven days before the end of the period, Stripe will send you a reminder by email; after that, the subscription will continue at the selected price.
