# AI Chat Interface V0 Template: Ship a Polished Chat UI in Under an Hour - Tool: V0 Templates - Last updated: July 2026 ## TL;DR The AI Chat Interface v0 template is a Beginner-friendly chat UI scaffold built on Next.js 14, shadcn/ui, and AI SDK v6. It ships a ChatShell layout, MessageList with MessageItem bubbles, a fixed InputBar, SuggestionChips to reduce blank-screen friction, and an animated TypingIndicator. Fork in five minutes, add OPENAI_API_KEY, and use the prompt pack to wire a real backend, add message search, or persist to Supabase. ## Frequently asked questions ### Is this V0 community template free to use? Yes. V0 community templates are free to fork for any V0 account. You will need an OpenAI API key for AI responses (charged per token by OpenAI) and a Vercel account for deployment (free tier available). No fee is attached to the template itself. ### Can I use this template commercially? Yes. V0 community templates carry no commercial-use restrictions. You own the forked code and can deploy it as a product, charge users for access, or include it in a client deliverable. If you build a subscription product, the Supabase persistence prompt from the pack is a good starting point before adding Stripe billing. ### Why does my fork break in V0 preview after I wire the AI backend? Two common causes: first, if you add a library that esm.sh cannot resolve (common with some AI SDK provider sub-packages), the preview will show a module import error — test those integrations after deploying to Vercel. Second, if OPENAI_API_KEY is missing or set with a NEXT_PUBLIC_ prefix, the server-side route handler cannot read it. Keep it server-only (no NEXT_PUBLIC_ prefix) in the Vars panel. ### How do I connect a real AI model to the template? Use the 'Wire a real AI backend via route handler' prompt from the pack above. It generates the complete app/api/chat/route.ts file with streamText from @ai-sdk/openai, reads OPENAI_API_KEY server-side, and returns a proper streaming response. Paste the prompt into your V0 chat and verify the response stream in the preview. ### The chat scrolls to the top after every AI response — how do I fix this? This is the most common pain point with this template. MessageList's shadcn/ui ScrollArea does not auto-scroll when messages are appended. Add a useEffect that watches the messages array and calls scrollRef.current?.scrollIntoView({ behavior: 'smooth' }) on the last MessageItem. The fix_prompt in the gotchas section above is copy-paste ready. ### Can I swap OpenAI for a different AI model? Yes. The AI SDK v6 interface is provider-agnostic — swap @ai-sdk/openai for @ai-sdk/anthropic, @ai-sdk/google, or any other provider in the route handler. Do this after deploying to Vercel production, not in V0 preview, since the preview sandbox has trouble resolving some provider sub-packages via esm.sh. ### Can RapidDev customize this chat interface for my product? Yes. RapidDev wires V0 chat UI templates to any AI backend, adds Supabase message persistence, and ships production auth with Clerk — typically in a few days.
