In this video, we’re building Wave AI — a full-stack second-brain AI agent from start to finish.
You’ll learn how to create an agent that can search the web, extract and summarize content from URLs, and chain tools together for advanced tasks.
We’ll also cover authentication with BetterAuth, subscriptions with Stripe, testing with TestSprite, Vercel AI Sdk and deployment to Vercel.
On the frontend, we’ll build a responsive UI with Tailwind v4 and Shadcn/ui.
