One credit = one AI assessment of one student submission. When you upload a student's essay or paper, eòlas uses one credit to mark it against the QS marking scheme and generate detailed feedback.
Credits never expire and are tied to your educator account. Students and parents always have free accounts — only educators need credits to run marking sessions.

No — credits never expire. You can buy a bundle at the start of the year and use them across the whole exam diet at whatever pace suits you. There's no pressure to use them by a deadline.
Credits are currently tied to individual educator accounts. We're working on department-level credit pools for school deployments — contact us if you'd like to discuss a shared school arrangement.
The educator always has the final say. You can review, adjust, and override any AI-generated mark before sharing it with students or parents. Credits are consumed when a marking run is triggered — but you're not locked into the result.
Credits that have already been used to generate assessments cannot be refunded, as the AI processing cost is incurred immediately. Unused credits (not yet applied to a submission) can be considered for a refund — please get in touch within 30 days of purchase.
No. Student and parent accounts are always completely free. Only the educator running the marking session uses credits. If a student's teacher adds them to a project, they can submit work and receive feedback at no cost to them or their family.
