With the help of an AI Agent powered by Groq’s Qwen LLM, and triggered instantly via a MacOS Shortcut, this system takes job descriptions from your clipboard and returns a ready-to-use HTML cover letter—right on your desktop. --- ⚙️ Workflow Breakdown 🔹 MacOS Shortcut – Trigger the Workflow Instantly The process begins with a MacOS Shortcut that captures job description text from your clipboard and sends it to a custom webhook in n8n. 🔹 Webhook Node – Receive and Process Input The webhook node receives the clipboard data, along with the required credentials for authentication. This node serves as the entry point to the full automation. 🔹 Field Mapping & Pre-Processing A series of basic logic nodes map and clean up the input fields.
