Using Braindumper Effectively: Complete Guide to AI App Planning

Braindumper is BuildWithAI's free wizard that turns app ideas into platform-specific code prompts. In 4 steps, you go from rough concept to detailed instructions for Lovable, Bolt, or Rork.

Most people get mediocre results because they don't know how to write effective descriptions. Here's how to get the most out of it.

The 4-Step Process

Describe your app - What it does, who uses it, key features
Choose app type - Web or mobile
Select platform - Choose from our recommended AI tools like Lovable, Bolt, or Rork
Get results - Initial prompt for all platforms + Knowledge File (PRD) for Lovable

Writing Better Descriptions

Your description quality determines your output quality.

Be Specific About the Problem

❌ Weak: "A productivity app"
✅ Strong: "A task manager for remote teams tracking progress across time zones"

Include Target Users

❌ Weak: "For people who exercise"
✅ Strong: "For busy parents wanting 15-minute home workouts"

List Core Features

❌ Weak: "Social features"
✅ Strong: "Users create groups, share progress photos, send messages"

Add Technical Details

❌ Weak: "Modern design"
✅ Strong: "Clean UI with dark mode, works offline, syncs when connected"

What You Get

All Platforms: Optimized initial prompt to copy/paste into the AI interface

Lovable Only: Additional Knowledge File (PRD) to upload for better context

Since these AI tools work similarly, the key is writing a great description rather than platform-specific tricks.

Common Mistakes

Too Vague: "Build a social media app"
→ Be specific about what makes yours different

Feature Overload: Listing 20+ features
→ Focus on 3-5 core features

No User Context: Missing who will use it
→ Include specific user scenarios

Pro Tips

The One-Shot Approach

Braindumper generates results once per session. To refine:

Copy the output
Edit it manually to add missing details
Or create a new Braindumper session with improved description

Template Approach

SaaS Template: "A [industry] tool for [users] that [main benefit]. Features: [3 key features]. [UI preferences]."

Mobile Template: "A [category] app for [demographic] who [goal]. Core: [3 features], notifications, offline mode."

Multi-Platform Testing

Try the same description with different platforms to see which output works best for your needs.

Real Examples

Before: "A fitness app for tracking workouts"

After: "A strength training tracker for intermediate lifters wanting progressive overload. Features: exercise library with videos, auto weight progression, workout timer, progress charts. Dark mode for gym use."

The "after" version generates specific technical requirements that actually match the user need.

Using Your Results

Initial Prompt: Copy and paste into your platform's AI interface
Knowledge File: (Lovable only) Upload PRD as Knowledge File for better context

Access saved results: Your Braindumper history.

Common Issues & Fixes

Output too basic? → Add more technical details
Doesn't match vision? → Be specific about UI/UX
Missing features? → List everything explicitly
Too complex? → Mention your skill level

Next Steps

Copy initial prompt to your platform's AI interface
Upload Knowledge File (if using Lovable) for additional context
Start building with your platform's AI assistance
Edit the prompt manually or create new Braindumper session if needed

The key to great Braindumper results: be specific about users, problems, and solutions. Vague ideas produce vague instructions.
