Hey there,

If you're looking for a creative, low-risk side hustle that blends AI with passive income, I’ve got something exciting for you: selling AI-generated greeting cards. Whether you want to offer digital printables or physical cards, this is a system you can start today, even if you're not a writer or designer.

🧠 Why Greeting Cards?

Greeting cards might seem basic, but they’re surprisingly profitable, especially when paired with automation.

• Low overhead: Digital cards cost nothing after creation. Physical cards? Printful prints and ships on demand. No inventory needed.

• High markup: A single card can sell for $5 to $10. Packs go for even more.

• Year-round demand: Think birthdays, holidays, weddings, graduations, and “just because” moments.

• Set it and forget it: Create once and keep earning as they sell.

This is one of the few creative side hustles that’s both personal and scalable.

✍️ Step 1: Use ChatGPT to Write Card Messages

Not a poet? Me neither. That’s why ChatGPT is the ultimate assisstant here.

Just drop in a few simple prompts like:

• “Write a cheerful birthday message for a friend”

• “Create a comforting sympathy card message”

• “Give me a witty Christmas greeting”

• “Write a short self-love affirmation”

It’ll generate great text in seconds.

You can fine-tune the tone to be funny, heartfelt, quirky, or minimalist.

After a quick edit, you’ve got your message ready to drop into a card.

👉 Pro Tip: Create themed batches. For example, 10 funny birthday messages, 10 affirmations, 10 pet-lover messages. This makes it easy to create bundles later.

Quick note: Don’t rely 100% on what ChatGPT gives you. It’s a great starting point and does the heavy lifting, but the real magic happens when you add your personal touch. Read the text and ask yourself, 'Would I want to buy this?' Then tweak the prompts. Think of ChatGPT as your writing assistant.

🎨 Step 2: Design Your Cards with Printful
