Automatically generates memecoin art and posts it to Twitter (X) powered by Google Gemini, NanoBanana image generation, and n8n automation.
🧩 Overview
This workflow creates viral style memecoin images (like Popcat) and posts them directly to Twitter with a witty, Gen Z style tweet.
It combines text to image AI, scheduled triggers, and social publishing, all in one seamless flow.
Workflow flow:
- Define your memecoin mascot (name, description, and base image URL).
- Generate an AI image prompt and a meme tweet.
- Feed the base mascot image into Gemini Image Generation API.
- Render a futuristic memecoin artwork using NanoBanana.
- Upload the final image and tweet automatically to Twitter.

🪄 How It Works
1️⃣ Schedule Trigger - starts the automation (e.g., hourly or daily).
2️⃣ Define Memecoin - stores your mascot metadata:
memecoin_name: popcat
mascot_description: cat with open mouth
mascot_image: https://i.pinimg.com/736x/9d/05/6b/9d056b5b97c0513a4fc9d9cd93304a05.jpg3️⃣ AI Agent - prompts Gemini to:
- Write a short 100 character tweet in Gen Z slang.
- Create an image generation prompt inspired by current meme trends.
4️⃣ NanoBanana API - applies your base image + AI prompt to create art.
5️⃣ Upload & Tweet - final image gets uploaded and posted automatically.
