Submit a podcast or video URL via the form. WayinVideo transcribes the full episode with speaker labels and timestamps. GPT-4o-mini reads the transcript and writes a complete LinkedIn article \u2014 headline, hook, full body, five key takeaways, and hashtags \u2014 following 7 writing rules for LinkedIn readability. The final article is saved to Google Sheets as a draft with Status set to Draft, ready for you to review and publish.\n\n## How it works\n- **1. Form \u2014 Podcast URL + Details** collects the video URL, episode title, host and guest names, target audience, and LinkedIn tone\n- **2. WayinVideo \u2014 Submit Transcription** submits the URL to the WayinVideo API for speaker-labeled transcription\n- **3. Wait \u2014 60 Seconds** gives the API time to start processing before the first poll\n- **4. WayinVideo \u2014 Get Transcript Results** polls the API for the task result\n- **5. IF \u2014 Transcription Complete?** checks if status equals SUCCEEDED \u2014 if not, loops back via a 30-second retry wait\n- **7. Code \u2014 Format Transcript** formats each segment as speaker label with timestamp and builds the text for GPT\n- **8. AI Agent \u2014 Write LinkedIn Newsletter** uses GPT-4o-mini with a structured system prompt to write the full article in labeled sections\n- **10. Code \u2014 Parse AI Output** extracts headline, article, key takeaways, and hashtags from the labeled output using regex\n- **11. Google Sheets \u2014 Save LinkedIn Draft** appends one row with all fields and sets status to Draft\n\n## Set up steps\n1. In **2. WayinVideo \u2014 Submit Transcription** and **4. WayinVideo \u2014 Get Transcript Results** \u2014 replace YOUR_WAYINVIDEO_API_KEY with your key from wayin.ai Account Settings\n2. In **9. OpenAI \u2014 GPT-4o-mini Model** \u2014 connect your OpenAI credential\n3. In **11. Google Sheets \u2014 Save LinkedIn Draft** \u2014 connect your Google Sheets OAuth2 credential and replace YOUR_GOOGLE_SHEET_ID\n4.
