How to Build Your First App in 15 Minutes with Lovable (Beginner Tutorial)

Step 1: Generate Your App Idea with AI

Before we even start building, we need to give AI a clear blueprint of exactly what we want to create. Head over to our website and use the free AI tool Braindumper to generate your project context.

• Go to the Braindumper page – you get 5 free generations per month.
• Select Lovable – it builds the entire MVP for you.
• Paste in your app idea – be as detailed as possible.
• Hit Generate and let the magic happen!

Step 2: Build the Core Features with Lovable

Now that we have our app context, let's open Lovable and start building.

• Paste the generated context from Braindumper into Lovable.
• Review the game plan and feature list.
• Hit enter – Lovable will start generating the code live.

Lovable sets up the entire app structure, including UI, backend, and database. Now, let's connect Supabase to handle authentication and data storage.

Step 3: Set Up Authentication with Supabase

• Create a free account on Supabase.
• Start a new project and copy the connection details.
• Go back to Lovable and link your Supabase project.
• Type "Set up Auth" in Lovable's chat – AI handles the rest!

Supabase will now manage user authentication, login, and sign-ups automatically.

Step 4: Implement Drag-and-Drop Kanban Features

• Ask Lovable to build the Kanban board layout.
• Implement drag-and-drop functionality for tasks.
• Ensure each user's tasks are stored in the database.

Now, when users log in, their tasks will persist – even if they log out and back in.

Step 5: Add AI Chat with DeepSeek

• Get an API key from DeepSeek or OpenAI.
• Add the API key to your project.
• Ask Lovable to build an AI chatbox for user support.
• Ensure the AI can access and analyze tasks stored in the database.

Now, users can chat with AI to get insights and suggestions on their tasks!

Step 6: Improve the UI with Mobbin

• Open Mobbin – a library of 100,000+ app design screenshots.
• Search for "Kanban" to find clean, modern UI inspirations.
• Copy a screenshot and paste it into Lovable.
• Ask Lovable to apply the design to your app's existing pages.

This ensures your app looks professional without spending hours on design.

Step 7: Deploy Your Web App with Vercel

• Click the GitHub button in Lovable and connect your account.
• Transfer the project to GitHub.
• Go to Vercel and import the repository.
• Click Deploy – and your app is live!

You can also add a custom domain in Vercel to give your app a professional touch.
