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.
