Text tutoring starts free.
Voice minutes & your own courses are the upgrade.
The tutor can talk through any subject for free by text, no card required, plus a free taste of voice tutoring every month. Uploading your actual course material, so it can quiz you from your own slides instead of guessing, plus a full voice-minute allowance, is what the paid plans unlock.

Whiteboard notes, real photos, and reusing an existing interactive simulation are usually free (0 credits). Only AI-drawn illustrations and freshly generated interactives cost credits, so day-to-day whiteboard use barely touches the pool.
