Anyone can sign up for a Proof Companion account. Account holders can generate and edit **one free proof**. A link to the proof can then be sent to students to try to solve online.

**For $10**, you can create and edit **as many proofs as you'd like** to send to your students.

A subscription lasts for one year and does not automatically renew. If you let it expire, all your created proofs will be saved for whenever you re-activate your subscription.
