An AI-powered system that automates podcast promotion workflows using GPT-4 and structured prompt chains.
Built with agent-first architecture to generate short-form clips, social captions, metadata, and thumbnail prompts from long-form content — reducing production time while preserving brand voice and emotional resonance.
PromoFlow AI accelerates podcast content workflows by auto-generating ready-to-publish assets from long-form video/audio.
This semi-automated system blends large language model (LLM) capabilities with human-in-the-loop QA to ensure quality, tone alignment, and rapid turnaround.
Problem
Producing marketing assets from weekly podcast episodes was time-consuming and inconsistent — requiring multiple team members to manually extract highlights, write captions, and format deliverables.
Solution
Designed a modular AI workflow that parses transcripts, identifies key moments, and generates clip selections, titles, captions, and thumbnail prompts in a consistent JSON format — all routed through a human QA checkpoint.
Results
- Reduced asset production time by 60%, saving 4–6 hours per episode
- Enabled faster go-to-market for weekly podcast releases
- Improved handoff clarity between creative and marketing teams
- Ensured consistent branding across platforms without additional headcount
- Extracts timestamps and themes from podcast transcripts
- Suggests 3–5 emotional hooks for short-form content
- Produces titles, captions, and thumbnail prompts tailored to social platform styles
- Generates Classic, Hybrid, and Modern caption styles per client brand voice
- Exports JSON handoff format for downstream automation
- Supports human-in-the-loop QA to refine before publishing
Built with structured prompt chains and Chain-of-Thought reasoning to enhance consistency and interpret nuance:
- Clip logic: Detects emotional tone and topic transitions to suggest high-retention segments
- Fallback behavior: Requests missing metadata instead of hallucinating when episode inputs are incomplete
- Style variation: Applies formatting and tone parameters for different social media personas
- Title optimization: Uses emotional resonance scoring + packaging prompt chains
- GPT-4 (ChatGPT) – prompt-driven generation engine
- NoteGPT + YouTube Transcript API – source ingestion
- n8n – automation and routing
- JSON – structured delivery format
- Google Sheets + Notion – content pipeline and team handoff
- Frame.io – video editing feedback loop
- (Claude used for prompt testing and alt caption generation)
- ✅ Live in weekly production
- 🟡 Refining prompt logic and JSON formatting
- 🔴 Automation layer + public repo polish (in progress)
- Smarter clip detection based on episode themes and emotional arcs
- End-to-end automation: JSON → publishing tool integration
- AI-generated thumbnails and auto-packaged delivery folders
This is a solo case-study project designed for AI workflow architecture.
