Watch Me Build & Sell A NEW AI App (step by step / easy / with ai)

Description: Walks through building and launching SubClimb, an AI-powered web app that automates writing Reddit posts to drive organic traffic. The creator validates demand via Reddit trends, designs an MVP with writer-voice and knowledge-base features, integrates Supabase for auth and storage, and prepares hosting and payment. Video demonstrates iterative testing, prompt tuning, and early-launch strategy for gathering beta users before monetization.

– Idea validation: Observes rising Reddit ad interest and personal viral posts to confirm demand; uses Google Trends and student examples as proof points.
– MVP features: AI post generator, per-app knowledge base, writer-voice templates (upload example Reddit posts), dashboard, recent posts and lightweight analytics — kept intentionally minimal.
– Build process: Uses Cursor with an OpenAI/Opus model to scaffold code, Supabase for database/auth, GitHub and Vercel for deployment; focuses on quick iteration and prompt tuning.
– Launch strategy: Acquire free beta users, iterate on prompt/UX based on feedback, then add Stripe payments to monetize after validation.

Quotes:

I can go viral on Reddit on one out of four posts consistently — I think I’ve cracked the code.

I hand-write every single post; maybe I can give them to a knowledge base and make an app out of it.

One post got 120,000 views, 13 inbound leads, and $18,000 of revenue.
