Create LinkedIn content from Telegram voice/text using Whisper, GPT-4 & Dumpling AI

🧾 What this workflow does This automation turns a Telegram voice or text message into a high-quality LinkedIn post using OpenAI’s Whisper, Dumpling AI and GPT-4, and then repurposes that same message into a content idea with visual inspiration using Dumpling AI.
