Add AI support to a v0 app
v0 (by Vercel) generates React and Next.js UI from prompts. Most v0 output lands in a real Next.js project — either exported to your own repo or deployed straight to Vercel.
Start free trialWhy a v0 app needs support anyway
v0 is exceptional at generating the interface — it has no opinion on what happens once real customers start using what it built. The support inbox starts the day you go live, not before.
Add support to your v0 app
Open the exported project
If you exported v0’s output to a Next.js project (the common case), open app/layout.tsx — the root layout that wraps every page.
Add the script tag to the layout
Paste it inside the <body>, or ask v0 itself (or Cursor/your editor’s AI) to "add this script tag to the root layout, before the closing body tag."
<script src="https://app.resply.io/widget.js" data-org-id="YOUR_ORG_ID" async></script>Redeploy on Vercel
Push to your connected repo, or redeploy from the Vercel dashboard. The widget goes live with your next deployment, same as any other change.
The questions you'll get asked
Answer each once in your docs, and Resply handles it automatically from then on.
FAQ
I’m still iterating inside v0’s own preview — should I add it there?
You can, but it only matters once the project is exported and deployed somewhere real users reach. Add it to the exported Next.js project when you’re ready to ship, not to every in-progress v0 draft.
Does this conflict with shadcn/ui components v0 generates?
No. The widget renders in an isolated Shadow DOM, so it doesn’t touch or get touched by your Tailwind classes or shadcn component styles.
