What changes

  1. Builds with your brand, copy and decisions in view
  2. Follows your rules for code and writing
  3. Saves what you decide where your other tools can see it

Set up

  1. In v0's prompt box: +MCPsadd a custom one.

  2. Paste your Alwen address and choose OAuth.

  3. Click Allow on the Alwen page.

  4. To let @alwen hand it work too, add a v0 key on its page in Alwen. It builds new apps and sites, not changes to your project, and sends the preview to your chat.
