Part 2: Step-by-Step Guide to Building AI Apps in Lovable

Step 1: Plan Your AI App (Critical Foundation)

Before touching Lovable, invest time in planning.

If you know exactly what you want to build, you can start directly on Lovable. However, planning ahead will make the process much smoother.

What to Define:

1. Core Purpose: What AI problem does it solve?
2. AI Features: Which LLM capabilities will you use?
3. Data Flow: How does data move through the app?
4. User Journey: How will users interact with AI?
5. Integrations: What external services do you need?

Use AI to Create Your PRD:

Leverage AI tools like ChatGPT, DeepSeek, or Claude to generate a Product Requirements Document (PRD). Use Lovable's Chat Mode to brainstorm feature ideas before jumping into development.

Example PRD for an AI Content Generator:

"Build an AI content generator that takes blog topics and generates 500-word articles. Users authenticate with Google/email. The app uses OpenAI GPT-4 API to generate content. Users can save articles, edit them, and export as PDF. Include a dashboard showing usage stats. Stripe subscription for premium features ($9.99/month = unlimited articles, free = 5/month)."

Time: 30-60 minutes

Step 2: Sign Up and Create Your Project

1. Visit lovable.dev
2. Click "Sign Up"
3. Enter email and create password
4. Verify email
5. Access your dashboard

Free Tier Includes:

5 daily prompts (enough for rapid development)

Time: 2 minutes

Step 3: Write Your Initial AI App Prompt

This is the most important step. The quality of your prompt directly determines the quality of your app.

Lovable's prompt-based system simplifies app creation. Simply describe what you want to build. The more specific you are, the better the results. Example: "Create a dashboard with user login, monthly sales in a line chart, and customer demographics in a pie chart."

Structure Your Prompt:

Include these elements:

1. App purpose (what it does)
2. AI features (which LLM, what model)
3. Core functionality (main features)
4. Data model (what gets stored)
5. User authentication (how users log in)
6. Integrations (payments, email, etc.)
7. Design preferences (style, theme, colors)

Example AI App Prompt (AI Email Assistant):

"Build an AI email assistant SaaS. Users sign up with Google or email. The app uses OpenAI GPT-4 to generate professional email responses. Features: 1) Paste email text, 2) Select tone (professional, casual, friendly), 3) AI generates 3 response options, 4) User can edit and copy. Include user authentication, email history dashboard, usage tracker (free = 10/month, pro = 500/month with Stripe), dark mode. Make it clean and modern with blue and white colors."

Pro Tips:

• ✅ Specific about AI model (GPT-4, Claude, Gemini)
• ✅ Mention API integration (OpenAI, Anthropic, etc.)
• ✅ Clear feature list
• ✅ Include payment model if needed
• ✅ Describe design preferences
• ❌ Don't: "Build a cool AI app"
• ❌ Don't: Overload with 50 features
• ❌ Don't: Vague about AI capabilities

Time: 15-20 minutes

Step 4: Generate Your App

1. Paste your prompt into Lovable's chat
2. Press Enter or Submit
3. Watch Lovable generate your app
4. Complete UI, database schema, and backend APIs are created

What Gets Generated:

• React frontend with responsive design
• Supabase PostgreSQL database
• Authentication flows (Google, email, etc.)
• API integration for LLMs
• Payment processing (if included)
• All necessary backend logic

Time: 3-5 minutes (automated)

Step 5: Preview and Test Your AI App

1. Click "Preview" button
2. Test all functionality
3. Test AI features (generate content, get responses)
4. Check payment flow if included
5. Test authentication

What to Test:

• User signup/login
• AI generation (submit prompt, get response)
• UI responsiveness
• Payment processing (if included)
• Error handling

Time: 10-15 minutes

Step 6: Refine Your AI App in English

Don't like something? Just describe the change. No coding required.

Each request refines your site. In one real-world project, the developer sent 28 prompts to Lovable—about half to fix bugs or small issues, half to add features. This cycle of rapid iteration is exactly how Lovable excels.

Refinement Examples:

• "Make the AI response area larger and add syntax highlighting for code snippets"
• "Add ability for users to favorite responses and access them in a history section"
• "Improve the prompt input to have character limit indicator (max 2000 chars)"
• "Change primary color from blue to purple throughout the app"
• "Add ability to export generated content as PDF"
• "Integrate with email so users can email themselves generated content"

Pro Tips for Refinement:

• ✅ One change at a time
• ✅ Be specific ("Make text larger" vs "Make font size 18px")
• ✅ Test after each change
• ✅ Use "revert" if something breaks
• ✅ Clear description of what you want

Time: 5 minutes per refinement

Step 7: Integrate AI Models (OpenAI, Claude, etc.)

Now connect your preferred LLM.

Option 1: Use Lovable's Built-In LLM Access

Some LLMs are already integrated. Your AI just works.

Option 2: Add Your Own API Key

Learn how to build a powerful app that integrates with any LLM using Lovable and OpenRouter! In this step-by-step overview, I'll show you how to set up seamless LLM integration, add secure payments with Stripe, and implement user authentication—all in one go.

Example request to Lovable:

"Add OpenAI API integration using my own API key. Create a settings page where I can paste my API key securely. Use GPT-4 Turbo for generating responses. Add token usage tracking so I can monitor costs."

Step 8: Connect Supabase for Backend (If Needed)

For user data, authentication, and persistence:

When building a to-do list app, for instance, Supabase becomes essential if we want our app's data to persist across multiple devices and users. Unlike local storage, which stores data only within a single device's browser, Supabase allows us to store data in the cloud.

What Supabase Adds:

• User authentication (email, Google, phone)
• Database (PostgreSQL) for storing data
• Real-time data syncing
• File storage for uploads
• Security and permissions

How to Request:

"Connect this app to Supabase. Set up user authentication with email and Google sign-in. Create a 'responses' table to store user-generated AI content with columns: id, user_id, prompt, response, created_at, favorite (boolean). Only show users their own responses."

Time: 10 minutes setup

Step 9: Add Payment Processing (Stripe)

For monetization:

"Add Stripe subscription integration. Two plans: Free (5 generations/month) and Pro ($9.99/month, unlimited). Include a pricing page with plan comparison. Show current plan on user dashboard. Auto-upgrade on payment."

Lovable makes this process smoother. "Add Stripe payment integration so customers can purchase digital products. Include a checkout page and order confirmation email."

Time: 5-10 minutes

Step 10: Deploy Your AI App

1. Click "Publish" or "Deploy"
2. Choose deployment option:
   • Lovable Subdomain (fastest, free)
   • Custom Domain (more professional)
   • GitHub + External Hosting (maximum control)

Time: 5 minutes

Click on the "Publish" button at the top of Lovable. Lovable will provide a subdomain where your app is now live and accessible to anyone on the internet.
