Frequently Asked Questions

What counts as an AI calculation?

Each time you upload a drawing and the AI analyses it to generate a U-value calculation, that counts as one AI calculation.

Can I change plans anytime?

Yes! You can upgrade or downgrade your plan at any time. Changes take effect immediately.

Do unused calculations roll over?

No, calculations reset at the start of each billing period. We recommend choosing a plan that matches your typical monthly usage.

Is there a free trial?

The Free plan lets you try the service with 5 calculations per month. Paid plans also have a money-back guarantee.
