Design systems are not only for exporting files. In the Website builder you can pick one to restyle a whole site. The colors, fonts, spacing and overall look change on every page.
This is the one place where BYQ applies a design system for you. It works on sites built in the Website Builder, not on Webflow, Framer or Figma projects.
Your own design systems from Made by you show up under My styles, so a system made from your own website can restyle your site right away. See Generate your own design system.
A restyle usually takes 3 to 5 minutes. If you do not like the result, Undo in the chat brings the previous version back.
A restyle touches every page, so it costs roughly 20 or more BYQ AI tokens in Best mode. The picker shows the estimate before you confirm, and if your balance is too low it offers to top up. To see what else uses tokens and what is free, read What uses tokens, and what is free.
For small color and font changes, the Style panel is lighter and cheaper.
