Reel Content Strategist: From URL to Viral Hook with AI + Sheets

Hello community

I wanted to share a recent workflow I built using n8n. It automates the entire content repurposing process for Instagram Reels. The flow is triggered via Telegram by simply submitting a Reel link.

Overview of the workflow

The flow downloads the Reel, extracts the transcript and description using AssemblyAI, then uses a selected language model such as OpenAI or Mistral to analyze the content. It identifies the niche and core message, generates three content ideas, and writes matching short-form scripts.

The audio is extracted from the video and converted to MP3 using FreeConvert’s API. All results including media links and generated content are automatically appended to a Google Sheet. Each step in the workflow has been documented using sticky notes for clarity.
