35+copy prompts

Use ChatGPT as the architect

Plan the app, define users, create acceptance criteria, design the user flow, generate test cases, and decide what to build first.

Use Codex as the engineering teammate

Give Codex focused tasks, repo context, constraints, and verification steps so it can edit files, run commands, and show you exactly what changed.

Ship with taste

Move past ugly prototypes. Learn the polish loop: responsive layout, useful microcopy, state, validation, performance checks, and a clean Hostinger deployment.

Final project: build a shareable micro web app

Your end goal is a small web app that friends can actually use. Keep the scope tight: one core user, one main workflow, and one polished interface.

Project menu

Study Sprint Planner: turn goals into daily focus blocks.
Gym Split Generator: build weekly routines and save favorites.
Budget Buddy: track categories with localStorage and charts.
Event Hype Page: RSVP-style landing page for a friend group.
Creator Link Hub: premium profile page with analytics mockups.

Definition of done

Has a clear user and problem. Has responsive mobile and desktop layouts. Has at least one interactive feature. Has a README with setup and deploy notes. Passes build or basic validation checks.

Capstone mega prompt

You are my senior product engineer. Help me build a small, polished web app in focused milestones.

Context:
- App idea: [paste your idea]
- User: [specific user]
- Stack: [React/Vite or HTML/CSS/JS]
- Deployment target: Hostinger static site

Deliverables:
1. Ask up to 5 clarifying questions only if critical.
2. Create a tiny PRD with user story, screens, data model, and acceptance criteria.
3. Split the build into 4 Codex tasks that can be tested separately.
4. For each task, write a Codex-ready prompt with constraints and verification.
5. Include a deploy checklist for Hostinger.

Ship it

Deploy on Hostinger

This course site is static, so you can upload the ZIP to Hostinger File Manager and extract it into your domain's public_html folder.

Upload the ZIP

Open Hostinger hPanel, go to Websites, choose your site, open File Manager, then open public_html.

Extract at the root

Upload the ZIP, right-click it, and extract. The files index.html, styles.css, and app.js should sit directly inside public_html.

Open your domain

Clear cache, load your domain, and test the course on mobile. Share it with friends and compare final projects.
