Pricing questions
What do I get for free?
Everything except everyday AI naming: the font finder, color picker, CSS copy, contrast check, page palette, fonts list and design-token export in every format (DESIGN.md with token values) — with no daily limits. You also get 3 free AI namings (one-time) to try Pro’s main feature.
What does Pro add?
“Name with AI” for everyday use (fair-use daily limit): semantic names for every color and text size, and DESIGN.md with AI design notes. Only token values and the site’s domain are sent — never page text. One license works in up to 5 browsers you use.
Can I cancel?
Yes, any time, from the link in your receipt email. You keep Pro until the end of the period you paid for. The lifetime plan is a single payment.
Who processes payments?
Dodo Payments, our merchant of record, handles checkout, taxes and receipts. Kernhue never sees your card details.
