What You Get Free, and Why There Is No Subscription
Creating an account gives you 500 free credits, and no card is asked for. There is no subscription and nothing to cancel — you buy credits only when you want more, they never expire, and everything you have already built stays yours even when your balance reaches zero.
What the 500 Free Credits Cover
They arrive the moment your account is created. There is no trial period, no card kept on file, and nothing that quietly starts charging when a trial runs out.
What Each Thing Needs
Every action has a minimum balance it will not start below. These are the floors, not the final price — what an action actually costs depends on how much work it does.
- Describing a topic in your own words — from 50 credits. This is the route your free credits are meant for.
- Building a topic from uploaded files — needs at least 1,000 credits, so it is not available on the free balance on its own.
- An AI-built course — from 150 credits.
- Reading a section aloud — from 70 credits, and every replay of that section is free.
There Is No Subscription to Cancel
Credits are bought as a one-off purchase. Nothing renews, no card is kept on file for automatic charging, and there is no plan running quietly in the background. If you came here hunting for a cancel button, there is nothing to cancel — stop buying credits and nothing further is ever charged.
What Happens When Your Balance Reaches Zero
Nothing is taken away. Your topics, roadmaps, explanations, quiz and exam history, certificates and progress all stay exactly where they were. A zero balance stops you generating new material; it does not lock or delete what you already have. The only thing that removes your content is deleting your account yourself.
Why Pay at All, When a General AI Chat Is Free?
A general assistant answers a question and forgets it. What you are paying for here is what remains afterwards: a roadmap through the subject that remembers where you stopped, quizzes and timed exams built from your own material, a mastery report naming your weak areas, an examination history you can look back over, audio you can keep, and a certificate with a public verification link an employer can check. If a one-off answer is genuinely all you need, a free chat is the better tool and we would rather say so.
