What You'll Learn
The #1 reason vibe coded apps fail isn't the AI — it's starting without a plan. People open Lovable, type "build me an app," and wonder why they've burned 40 credits on something that doesn't work.
30 minutes of planning saves hours of wasted credits and frustration. This guide gives you a repeatable ritual to follow before you touch any tool.
Why Planning Prevents Wasted Credits
Every unfocused prompt costs credits. Every "undo that" costs credits. Every "actually, I wanted it to look different" costs credits.
The AI isn't a mind reader. When you give it vague instructions, it guesses — and it guesses wrong about half the time. Planning gives the AI exactly what it needs on the first try.
Pro tip: Think of each prompt as a dollar bill. Would you throw a dollar at a vending machine without knowing which button to press?
The One-Paragraph App Description
Before you do anything else, describe your app in one paragraph. If you can't explain it simply, you'll definitely confuse the AI.
Here's a test: read your description to a friend. If they say "so what does it actually do?" — rewrite it.
Bad example: "I want to build a platform that connects people and helps them manage things and has a social component with analytics."
Good example: "A habit tracker where users log 3 daily habits, see a streak counter, and get a weekly email summary of their progress."
See the difference? The second one tells the AI exactly what to build.
How to Define Your MVP (3 Features Max)
The MVP rule: pick exactly 3 core features. Not 5. Not 10. Three. Everything else is v2.
This is the hardest part because everything feels essential. It's not. Your app needs to do one thing well before it does ten things poorly.
- Scope creep (what most people do):
- User authentication
- Dashboard with charts
- Habit logging
- Social feed
- Friend system
- Push notifications
- Gamification with badges
- Admin panel
- API integrations
- Dark mode
- MVP thinking (what actually works):
- User authentication
- Log daily habits
- View streak counter
That's it. Ship that. See if anyone uses it. Then add features based on what real users ask for.
Warning: If your MVP has more than 3 features, it's not an MVP. Cut harder.
The User Flow Sketch
No fancy tools needed. Paper and pen or a notes app. Walk through what actually happens when someone uses your app.
Ask yourself these questions in order:
Draw boxes and arrows. It doesn't need to be pretty. It needs to be complete enough that you could hand it to a stranger and they'd understand the flow.
Try this: Open your notes app and write out your user flow as a numbered list right now. It takes 5 minutes and saves at least 10 prompts.
Questions to Answer Before Opening Lovable
Answer these 10 questions before you write a single prompt:
If you can't answer all 10, you're not ready to build yet. And that's fine — spend another 10 minutes thinking.
Your App Brief Template
Copy this template and fill it in before every build. Paste the completed version as your first prompt.
APP NAME: ___ ONE SENTENCE: This app helps [WHO] to [DO WHAT] so they can [GET WHAT RESULT]. 3 CORE FEATURES (MVP only): 1. ___ 2. ___ 3. ___ USER FLOW: 1. User arrives at → [landing page / login / dashboard] 2. User does → [main action] 3. User sees → [result / confirmation] DATA THAT NEEDS TO PERSIST: - [What needs to be saved to a database] WHAT THIS IS NOT: - [Feature explicitly NOT in v1] - [Another feature NOT in v1] DESIGN REFERENCE: - Similar to [app/website they know] - Colors: [palette] - Vibe: [minimal / playful / professional]
