PromptCraft Series #3 Lovable & Replit: How to Start Prompting Without Coding

PromptCraft Series #3 – Lovable & Replit: Start Prompting Without Coding

✨ PromptCraft Series #3

"Lovable & Replit: How to Start Prompting Without Coding"

🗕️ New post every Monday

🧠 Quick Recap

  • ✔ Why prompt engineering is the new no-code skill
  • ✔ The anatomy of a perfect prompt

Now, let’s get practical and start building.

Today, you’ll learn how to:

  • Set up your first prompt block
  • Connect to OpenAI (or other LLMs)
  • Customize your prompt workflows without writing code

🔹 1. Setting Up Your First Prompt Block

🏗 On Lovable:

  • Head to your app workflow.
  • Drag a Prompt or AI block.
  • Type your prompt using the structure from Blog #2:
"Act as a [role]. Your task is to [task]. Respond in [format]..."

Example prompt:

"Act as a social media strategist. Your task is to write a catchy Instagram caption for a new fitness app. Keep it under 20 words. Tone: Energetic and friendly."

🏗 On Replit:

  • Go to your Replit project.
  • Install the OpenAI package.
  • Create a prompt string:
const prompt = "Act as a social media strategist...";
  • Use the OpenAI API call to send this prompt.

🔹 2. Connecting OpenAI or Other LLMs

On Lovable:

  • Go to Settings > Integrations.
  • Select OpenAI or Anthropic Claude.
  • Paste your API key.

On Replit:

  • Get your OpenAI API Key.
  • Authenticate in your code:
const configuration = new Configuration({
    apiKey: process.env.OPENAI_API_KEY,
});
const openai = new OpenAIApi(configuration);

Now you can send prompts and receive AI-generated responses.

🔹 3. Drag-and-Drop Workflows + Prompt Customization

On Lovable:

  • Connect AI blocks to user inputs, conditional logic, API calls, and outputs.
  • Add variables inside prompts (e.g., [user_name], [product_description]).
  • Set temperature, max tokens, and other settings easily.

On Replit:

  • User input ➔ Prompt ➔ LLM ➔ Output display.
  • Change response length and creativity (temperature).
  • Use if/else logic or add multiple prompt versions.

📝 Pro Tip: Always Test and Iterate

Don’t settle for your first output. Tweak the wording, formatting, and settings to find the sweet spot where the AI gives consistently helpful results.

📈 Exercise for This Week: Your First AI Flow

  • Choose a simple task (e.g., summary or greeting message).
  • Set up a prompt block in Lovable or Replit.
  • Test different versions of your prompt.
  • Try changing the temperature to see how creativity changes.

Behind the Scenes: How Generative AI Creates Music, Art, and Stories

When Machines Dream We’re living in a world where machines don’t just compute—they create. Generative AI is writing novels, composing symphonies, and painting pictures. But what’s really going on behind the screen? This post pulls back the curtain to reveal how generative AI actually creates —from writing a bedtime story to composing a lo-fi beat. Whether you're a curious creator or tech enthusiast, you’ll see the art of AI through a new lens. What is Generative AI, Really? Generative AI uses machine learning models—especially neural networks—to generate new content based on learned patterns. Trained on vast datasets, these models produce original music, images, and text based on user prompts. 1. How AI Writes Stories (e.g., ChatGPT, Claude) Step-by-step: You give a prompt: “Write a story about a lonely robot who finds a friend in the forest.” The model (like ChatGPT) draws on its training data to predict and generate the most likely next word, sentence, or paragr...
