In this video I build and deploy a complete Full Stack AI SaaS app using the PERN stack (PostgreSQL, Express, React, Node.js). I start by showing you the full demo: a clean homepage with tools, testimonials, pricing, and then a dashboard where every AI tool lives—article generator, blog title generator, image generator, background remover, object remover, and a resume analyzer. The important part is not just generating content, but building it like a real product with authentication, plans, and a proper UI flow. I integrate Clerk for sign-in/sign-up, account management, and subscription billing so premium-only AI features are locked behind the paid plan (you saw the image generator prompt blocked until upgrading). For the database I use Neon serverless Postgres so every creation history can be stored reliably. Finally, I deploy the project online for free on Vercel. If you finish this project, you can add the live link in your resume or even submit it as a strong college project—because it’s a real SaaS with auth, billing, and multiple AI tools, not just a basic CRUD app.
