I Built an AI SaaS with Supabase in 12 Minutes

👉 Try Supabase here: https://supabase.link/ockCIUT Building AI apps is easier than ever... But if you actually want to build something people can use, you need a REAL backend… In this video, I build a complete AI-powered launch funnel generator using Supabase as the backend and Lovable as the frontend builder… Users enter a product idea, the AI generates a complete landing page, and everything is stored inside Supabase — including projects, generated funnels, users, and leads… Key Ideas Fastest way to go from idea to working app All-in-one backend — no need to stitch together multiple services Built on Postgres — portable and not locked in Perfect for building AI-powered apps Build in a weekend, scale to millions Chapters 00:00 Building a real money-making AI app 00:25 Why Supabase? 00:52 Planning the app 01:29 Creating a Supabase project 02:02 Creating the database tables 03:12 Building the app with Lovable 04:38 Connecting Lovable to Supabase 06:17 Testing the AI funnel generator 07:26 Viewing the data inside Supabase 08:06 How Supabase powers the backend 08:14 Adding a real payment flow 08:32 Monetizing the funnel-generation service 09:38 Connecting Stripe in test mode 10:09 Testing a new product 10:37 Stripe checkout demo 11:04 Final app flow 11:15 How this becomes a real business 11:54 Final thoughts SQL Schema Used (to build the tables within Supabase): “create extension if not exists pgcrypto; create table if not exists profiles ( id uuid primary key default gen_random_uuid(), created_at timestamptz default now() ); create table if not exists launch_projects ( id uuid primary key default gen_random_uuid(), user_id uuid references profiles(id), product_name text, product_idea text, target_customer text, pain_point text, offer text, price text, goal text, created_at timestamptz default now() ); create table if not exists generated_funnels ( id uuid primary key default gen_random_uuid(), project_id uuid references launch_projects(id), user_id uuid references profiles(id), hero_headline text, subheadline text, benefits text, features text, faq text, cta text, created_at timestamptz default now() ); create table if not exists leads ( id uuid primary key default gen_random_uuid(), project_id uuid references launch_projects(id), name text, email text, created_at timestamptz default now() );” Lovable Prompt (APP BUILDER): “Build a clean, modern web app called MY FRIEND FUNNEL that acts as an AI-powered strategic marketer. The user enters their name, email, product name, product idea, target customer, main pain point, offer, price, and goal. When they submit the form, save the data to Supabase, generate a polished one-page product landing page, save the generated funnel, and display it immediately. Keep everything on a single page with no login or dashboard—just a simple flow from form → generated funnel.” #supabase #lovable #ai #saas #postgres #webdevelopment #aitools #buildinpublic #nocode #kingyai Lovable ADD PAYMENT Prompt: “Update My Friend Funnel so users are paying for the funnel-generation service, not the product they're creating. The flow should be: 1. The user enters their product information. 2. They click "Generate Funnel." 3. Before the AI generates the landing page, present two options: - Generate for FREE (demo mode) - Unlock Premium for $19 via Stripe Test Mode 4. Once the user selects either option, generate the landing page. 5. Save the user's contact information to `leads`, the product details to `launch_projects`, and the generated landing page to `generated_funnels`. 6. Display the completed landing page. The payment is for using the My Friend Funnel service—not for purchasing the user's product. Use Stripe Test Mode so I can demonstrate the full checkout flow without charging any real money, while still keeping a free option available for the video. Keep the experience simple: Enter Product → Free or Paid → Generate Funnel → Display Landing Page.”
