How to Integrate AI Services into Lovable Projects
Lovable makes it easy to integrate AI services into your web applications. Whether you want to build an AI-powered landing page, a text-generation tool, or a full SaaS app, Lovable’s built-in integrations with services like OpenAI, Groq, Claude, Deepseek, and Mistral make it possible without writing backend code. Here’s how to do it:
Choose the AI Feature You Need
Before you start building, define what you want the AI to do:
- Generate or enhance text (e.g. email writer, tweet generator)
- Classify or summarize content
- Analyze images
- Personalize responses
- Integrate with a specific LLM API
Plan with Prompts First
Use Lovable’s chat interface to describe your feature in simple terms. For example:
Lovable will scaffold the UI, suggest components, and let you preview the app quickly.
Connect to a Backend with Supabase
AI features often need backend logic. Supabase provides:
- Database for user data
- Auth for login/signup
- Edge Functions for calling external APIs securely
Set up Supabase early in your project to avoid UI/backend mismatches.
Use Edge Functions for AI Calls
To safely call AI APIs, create an Edge Function inside Lovable:
- Add your API key to the Supabase by submitting this via the secrets form
- Let Lovable generate the edge function code
- Ensure you use function calling if your API returns structured data (e.g. calories, macros, tweet threads)
Prompt Example:
Structure your OpenAI function calling schema with defined fields like:
Make It Interactive
Add buttons or form actions for:
- Submitting text to the AI
- Uploading an image
- Toggling between modes (concise vs friendly tone)
Lovable lets you:
- Attach functions to buttons
- Animate interactions
- Show real-time results with minimal prompting
Use screenshots and phrases like “make this smoother” to guide the design.
Advanced UX Tip: Implement side-by-side live previews of the AI response. Use left/right layout blocks or tabs to let users compare outputs.
Use External Services (Optional)
Some popular integrations for AI workflows:
- Resend – send emails after form submission
- Groq API – blazing fast LLM inference
- Stripe – paywall access to AI tools
- Replicate – generate or transform images
Prompt Example:
Payments Tip: Lock advanced AI features behind a Stripe subscription. Use conditional flows like:
Test and Iterate
- Use preview links to test mobile responsiveness
- Check performance with multiple API calls
- Share your project for feedback
- Use chat history to revert changes or refactor
Publish and Promote
When you’re ready:
- Deploy with a single click
- Use Lovable Launch to get visibility
- Add OG tags and SEO title/description in the meta panel
- Submit your app to Product Hunt, communities, and social media
Debug and Improve Prompts
- Be specific with system messages: “You are a helpful nutritionist.”
- Test function calling by mocking inputs.
- Use
console.log()
inside edge functions to trace logic. - Use screenshots when asking Lovable to debug a layout.
Prompt Tip: If the AI fails to use your context (e.g. user’s meals), say:
Troubleshooting
Missing data in AI prompts?
Missing data in AI prompts?
Make sure you include context like user history or previous entries.
UI not updating?

Use chat-only mode to debug one step at a time.
Streaming issues with Groq/OpenAI?
