What is n8n?

n8n (pronounced “n-eight-n”) is an open-source workflow automation platform that allows you to connect apps, APIs, databases, AI models, and cloud services without writing extensive code.

Instead of manually performing repetitive tasks, n8n lets you create automated workflows using a visual drag-and-drop editor.

A workflow consists of multiple nodes, where each node performs a specific action.

Example:

Telegram Message
        ↓
AI Generates Reply
        ↓
Save to Google Sheets
        ↓
Send Notification

Everything happens automatically.
