1. The public beta
C8T offers interactive learning, tests, progress records and study tools. Independent signup is for people aged 16 or over. Younger learners need an account created by a parent or guardian through an available Family account. If Family setup is unavailable, younger learners must wait rather than create an independent account.
2. Availability and prices
The Free tier has a 60-minute allowance per rolling 24 hours. Paid checkout is not open yet. Published subscription prices describe the planned paid plans; showing a price or choosing a plan does not take a payment. Story Mode and child assessments are in development.
3. This edition
Public-beta edition 1.3-public-beta, dated 8 November 2026. This edition takes effect when public-beta registration opens. Material changes will be dated and shown before they apply.
