AI credits are the prepaid balance that pays for the AI features in Ekati — above all the AI tutor you can open inside a lesson. Nothing is billed behind your back and there is no monthly subscription: you buy a number of credits, they are used a little at a time, and you top up when they run low.

The page is in three parts. At the top, your balance. In the middle, the top-up box where you choose how many credits to buy. At the bottom, your credit history — every movement, with the payment reference that caused it. Open it from AI Credits in the sidebar.

One credit is one small unit of AI work. The price in francs is printed next to the box as you type, so you always see the amount before you commit to anything.

The number at the top is what is left

The line under the title reads Balance: N Credits, with the model that will answer you. That figure is what remains, not what you have spent in total. Behind it sit two other numbers: everything you have ever been given, and everything used so far. The balance is the difference, and it is the only number you spend.

Refresh when you are unsure

The number is checked against the AI provider each time you open the page, but if you have just used the tutor on another device it may be a little behind. Press Refresh and the figure is fetched again immediately. If the balance reaches zero, the screen says so and offers you the top-up box.

Nothing goes quietly below zero

This is prepaid money, so the balance stops at zero instead of turning into a debt. When it is empty, the AI tutor stops answering and tells you so plainly, with a button that takes you straight to the top-up page. You will never open a negative balance by accident, and you will never be surprised later by an amount you did not agree to.

Some schools switch on a free-model fallback: when the paid balance hits zero, requests move to free models until their rate limit is reached. When that setting is on for your school, a notice at the top of the page says so, and you should expect the answers to get shorter-lived rather than your balance to go below zero.

Tick a child, type a number, repeat

Signed in as a parent, the top-up box lists each linked child with their name, their email address and their own remaining balance. Tick a child, type how many credits they should get, then tick the next. The amount shown on the button is the total for the whole selection, and one payment covers all of it.

Each child receives the credits on their own account, never pooled into one shared pot. Two children doing a lot of AI work therefore need two top-ups, and you can see at a glance who is running low.

What the history shows

The credit history lists every movement with its type, the number of credits, the payment reference and the date. When you fund several children in one payment, each of their allocations appears as its own line under the same reference, which makes a missing credit easy to trace to a particular child.

Once the payment is confirmed, the credits are yours immediately. If a child’s balance has not moved a few minutes after the confirmation, refresh their card in the tutor or come back to this page and press Refresh.
