• Cloudinary Account – For image hosting (optional, uses unsigned upload)
• Recipient Info – Names and short descriptions of people you want to send cards to

How It Works

The workflow is fully agentic, meaning AI agents make decisions and take actions autonomously:

1. You provide a name like "Alex Chen" and a description: "Frontend developer who loves hiking and coffee"
2. The research agent searches the web to find more context. Maybe Alex recently ran a marathon or started a new job
3. Another agent finds photos of Alex online (you approve which one to use)
4. The message agent writes something like: "May your code compile on the first try and your trails always have good views. Happy Holidays!"
5. Four prompt agents (using GPT-4, GPT-4 Mini, GPT-5 Mini) each create a unique image prompt based on Alex's interests + Christmas theme
6. Gemini 2.5 Flash generates 4 different maximalist Christmas card images
7. You review and pick the best one

Why 4 images? Different AI models interpret prompts differently. You get variety and can pick the vibe that fits best.

Pro Tips

Better descriptions = better cards. Instead of "likes sports," try "obsessed with Manchester United, runs every morning, loves craft beer."

Photo quality matters. The AI uses the selected photo as reference. Clearer photos = better results.

Tweak the prompts. The workflow uses "maximalist" Christmas style by default. Edit the AI prompts to go minimal, vintage, or cyberpunk if that's more your vibe.

Batch processing. Run the workflow multiple times with different recipients. Each card is unique.
