How it works
This workflow lets users generate AI images directly from Telegram messages using:
Google Gemini API – to convert text to detailed, high-quality image prompts.
Pollinations API – to generate free AI images from the prompts.
Telegram Bot – to interact with users and return generated images instantly.
It’s fully automated using n8n — from text message to stunning image, all in one flow.
Perfect for creators, content marketers, or anyone wanting quick visuals on the go.

🧩 Estimated setup time: ~10–15 minutes
