Buy me a coffee
I am Viktor. I build EnvolPrep on my own and I pay the AI bill with my own card. The practice stays free either way. Coffee just makes it easier.

A pass gives you more AI feedback on Writing and Speaking than the free daily allowance, for a day, a week or a month. Passes are the one thing I sell.
One payment. No subscription and no auto-renew. A pass bought while another is active adds its days at the end, except a pass with a higher limit, which starts at once. Every pass also gives more AI Tutor sessions a day. AI reviews count in 24-hour blocks from the moment you pay. Paid securely through Stripe, so we never see your card details. Refund policy
The money pays for two things: the AI that reads your answers, and the server that runs the site. That is the whole list.
A coffee is a gift, so there is nothing to refund. The passes have their own refund policy.
