AI prepares and refines the lesson. You launch it, students join, Syllonaut collects responses and helps with evaluation. Free shows the full workflow; paid plans add more AI capacity, repeated use and advanced tools.
An AI lesson is not a one-off material. The AI allowance is used only for new creation and AI edits; on paid plans, finished lessons can be launched and taught repeatedly without using the AI allowance.
For first lessons and occasional use with no payment card.
For regular teaching: create new lessons with AI, then teach the finished lessons again without using the AI allowance.
For intensive lesson work with AI point suggestions, worksheets and organisation tools.
Teacher Pro subscribers can buy one-time packs, valid for 12 months and used after the plan allowance:
Alerts about possible AI use in student responses: This is an AI/heuristic signal for teacher review, not proof. Scores do not change automatically.
Devices on paid accounts: For security reasons, paid features, including launching lessons, can be used only on trusted devices. Teacher and Teacher Pro: up to 3 active devices and 5 newly added within 30 days. Team, School and Campus: up to 5 active devices and 10 newly added within 30 days per teacher account. Older devices can be removed in subscription management, or in school management for school accounts. Students join without an account and do not count toward the limit.
Technical requirements: Syllonaut runs in a current browser (Chrome 111+, Edge 111+, Firefox 111+, Safari 16.4+) with JavaScript and cookies enabled and needs an internet connection. Details on devices, network and file formats: technical requirements.
The allowance for new AI lessons and AI edits is separate from the AI grading allowance. Free creation allowances reset at the start of each calendar month; Teacher and Teacher Pro reset with the billing cycle, with annual subscriptions using monthly intervals anchored to the subscription start date. Teacher Pro also includes 60 AI gradings in the same allowance period. Your account shows the exact remaining counts and next reset date. Launching and reusing finished lessons does not consume these allowances.
Teacher and Teacher Pro can be purchased directly through Stripe. Team, School and Campus can be ordered with school administration, by card or invoice.
Owners and administrators manage members, invitations, the shared AI allowance and billing. School and Campus also include a shared lesson library.
