Talk to usHow it works
- AI credits: an AI question or edit uses 1 credit; creating a diagram from scratch uses 2. Credits renew on the first day of each month and the daily cap renews every day, in UTC; unused credits do not roll over.
- Subscription: it renews automatically every month or every year, depending on the plan you chose, until you cancel it from your account. You keep Pro until the end of the period you paid for.
- If you stop paying: your account goes back to the Free plan and nothing is deleted. Diagrams over the Free limit become read-only: you can open and export them.
- Payments: processed by Paddle, which acts as Merchant of Record: it sells you the subscription and issues the invoice. We never see or store your card details.
- Refunds: see the refund policy.
