Adding a Chat to Your Next.js App in 10 Minutes with the Vercel AI SDK

`useChat`, a route handler, and one provider key — and your app has streaming AI in it.

The big idea

The Vercel AI SDK turns 'add AI to my app' from a week of work into an afternoon. `useChat` on the client, a tiny route handler on the server, and a provider key in `.env`. Streaming, tool calls, and structured output all included.

Some examples

You add `useChat` to a page and have streaming chat working before lunch.
Switching providers — Anthropic to OpenAI — is one import change with the SDK's adapters.
`generateObject` with a Zod schema replaces 200 lines of homemade JSON-parsing code.
Tool calling with the SDK is a single `tools: { }` config instead of custom routing.

Try it!

Spin up a fresh Next.js app, install `ai` and a provider, wire `useChat` to a `/api/chat` route. Ship in an hour.

Practice this safely

Try this with a school, hobby, or family example where the stakes are low. Use the AI output as a draft you can question, not as the final answer.

Ask AI to explain Vercel AI SDK in plain language, then underline anything that sounds uncertain or too broad.
Give it one detail from "Adding a Chat to Your Next.js App in 10 Minutes with the Vercel AI SDK" and ask for two possible next steps plus one reason each step might be wrong.
Check useChat against a trusted source, teacher, adult, expert, or original document before you use it.
