⚡ 292 views · 🎬 Content Creation & Video
💡 Pro Tip — Twitter’s API is paid now, which makes simple data pulls expensive. ScraperNode is a community node that scrapes Twitter profiles and posts without needing API access.
Description
Turn your favorite podcast episodes into engaging social media content automatically. This workflow fetches new episodes from an RSS feed, transcribes the audio using OpenAI Whisper, generates a concise summary using GPT-4o, and drafts a tweet. It then sends the draft to Slack for your review before posting it to X (Twitter).
Who is this for
Content creators, social media managers, and podcast enthusiasts who want to share insights without manually listening to and typing out every episode.
Key Features
- Large File Support: Includes a custom logic to download audio in chunks, ensuring stability even with long episodes (preventing timeouts).
- Human-in-the-Loop: Nothing gets posted without your approval. You can review the AI-generated draft in Slack before it goes live.
- High-Quality AI: Uses OpenAI’s Whisper for accurate transcription and GPT-4o for intelligent summarization.
How it works
- Monitor: Checks the Podcast RSS feed daily for new episodes.
- Process: Downloads the audio (handling large files via chunking) and transcribes it.
