Lovable (AI-powered app and website builder)

Main Features & Usage Tips

1. Nail the Opening Prompt:
   • The first prompt is crucial; it sets the foundation.
   • Best practice: break the prompt into three parts:
     • Overview of what you’re building (e.g., habit tracking SaaS).
     • Detailed functionality needed (e.g., login/signup, dashboard features).
     • Style/aesthetic preferences (e.g., clean, modern, color scheme).
   • A well-crafted first prompt can get you 70-80% done.
2. Use Screenshots and Example Images:
   • Feeding example images or screenshots into Lovable dramatically improves accuracy.
   • Images communicate design/functionality better than text alone.
   • This can save hours of frustration.
3. Restart Build if First Output is Poor:
   • If the initial build is off-base, delete the project and start over with a refined prompt.
   • The first build anchors the rest of the project; a bad start leads to complications later.
4. Set Up Authorization and Payment Early:
   • After the initial build, immediately prompt Lovable to set up user authorization (e.g., via Supabase) and payment processing (e.g., Stripe).
   • Doing this early avoids integration headaches later in the project.
5. Never Share Stripe API Keys Directly in Chat:
   • For security, do not paste Stripe API keys directly into Lovable’s chat.
   • Instead, have Lovable create a secret variable in Supabase to store API keys securely.
   • Prevents accidental exposure of sensitive keys in the frontend.
6. Use the Revert Button Frequently:
   • Lovable’s revert feature allows you to roll back to previous versions.
   • Acts as a checkpoint system, enabling fearless experimentation without risk of losing progress.
7. Limit Instructions Per Prompt:
   • Avoid giving Lovable more than three style/front-end changes per prompt.
   • For complex functionality changes, limit to one instruction per prompt.
   • Overloading prompts often causes errors or unintended changes.
8. Align Terminology with Lovable:
   • Sometimes Lovable misinterprets which elements to change.
   • Ask Lovable what it calls certain elements or provide specific element IDs/classes.
   • Ensures both user and AI are “speaking the same language” to avoid miscommunication.
9. Image Handling is Tricky:
   • Lovable struggles with uploading and displaying custom images reliably.
   • Recommended workaround: use image URLs from Unsplash or upload images to Supabase storage buckets.
   • These methods ensure images display correctly.
10. Mobile Optimization is Effortless:
    • Lovable can fully optimize a site for mobile responsiveness with a single prompt.
    • Adjusts navigation, spacing, touch targets, and readability automatically.
    • Saves significant time compared to manual mobile optimization in other builders.
11. Finishing Touches & SEO:
    • SEO optimization (meta titles, descriptions), favicon, and open graph images can be added in 1-2 prompts.
    • Lovable can assign appropriate SEO metadata and update social sharing images quickly.
    • Also, you can remove the Lovable branding tag from your project in settings before going live.
