First thing, I suggest you to check the benefits of the subscription.
The full subscription (Researchers) allow you to use the unlimited version of the platform, including slide creations and unlimited use of illustrations.
The subscriptions also include an incredible benefit: on demand illustration service.
It means that you can request new illustrations for the platform. Isn't it great?
Student's subscription, by the way, is only a little more limited, but with a great price discount.

And here are the subscription options, with incredible pricing:

Full subscription: 9 USD/month for researchers in the annual subscription
