💡 Why use Lovable for this

Lovable is an AI app builder that generates full-stack web apps from natural language. The practical workflow is to generate the first 80% with prompts, then switch to Code Mode to add business logic, fix edge cases, and polish the UI. Plan gotchas: Code Mode is available on all plans, but free tier has limited daily messages and no custom domain. Pricing and features checked 2026-10-15.

🛠️ How to Build Apps with AI + Code Mode (4 steps)

Step 1

Open Lovable and click 'New App'. Give it a name. In the chat box, describe your app in 2-3 sentences. Include core features, data types, and who will use it. Example: 'Build a customer portal where clients can view their invoices, pay via Stripe, and see payment history. Include user roles: admin and client.' Press Enter. Lovable will start generating the full codebase. This takes 1-3 minutes.

Step 2

After generation, preview the app by clicking the 'Preview' button (top right). Test each feature. Make a list of 3-5 things that need improvement — for example, 'The invoice list doesn't show due dates' or 'The Stripe payment form is missing an amount field'. Do NOT ask the AI to fix everything at once; you'll fix them individually in Code Mode.

Step 3

Switch to Code Mode by clicking the 'Code Mode' toggle at the top of the editor panel. The view changes to a file browser (left sidebar) and a code editor (main area). You'll see the project structure: src/ for React components, functions/ for Supabase edge functions, etc. Don't be intimidated — you only need to edit one file at a time.

Step 4

Identify which file likely contains the code you want to change. For example, to fix the invoice due date, look for a component named 'InvoiceList.js' or similar. Click it in the file browser. A brief description at the top of each file (added by Lovable) explains its purpose. Use that to navigate. Once open, find the relevant section — look for things like 'table', 'row', or 'date' — and make your edit. For instance, add a new column <td>{invoice.dueDate}</td> within the table. The editor supports syntax highlighting and autocomplete.

📦 What you'll get

After completing these steps, you will have a working web app with a custom feature (e.g., invoice due dates) that was not generated by the initial prompt. The app will be deployable via Lovable's hosting.

⚠️ Common mistakes

❌ Trying to edit code without understanding what the file does.

Why it happens: The file tree is unfamiliar.

✅ Quick Fix: Read the description at the top of each file and look for comments — Lovable adds them automatically.

❌ Forgetting to save the file before previewing.

Why it happens: Code Mode doesn't auto-save.

✅ Quick Fix: Hit Ctrl+S / Cmd+S after every edit, or look for the 'Unsaved changes' indicator.

❌ Panicking when the code breaks and reverting to natural language.

Why it happens: Errors feel intimidating.

✅ Quick Fix: Read the error message in the preview pane; it tells you exactly which line is wrong. Most errors are typos or missing imports — fixable in seconds.
