+1. Gets the caption manifest for the video

-**The Development Journey** 📈
+**Modern Development Velocity** ⚡
+
+What strikes me most about this project is the development speed enabled by modern AI tooling. From initial concept to published NuGet package took just a few hours - a timeframe that would have been unthinkable just a few years ago.
+
+**The AI-Assisted Workflow** 🤖
 
-The project evolved through several key commits:
+This project showcased the power of combining multiple AI tools:
 
-1. **Initial Implementation** (`2a2c702`) - Core functionality with basic transcript extraction
-2. **NuGet Packaging Fixes** (`a22d4ce`) - Resolved packaging and dependency issues
-3. **Version Management** (`0ce044f`) - Added automated version bumping
-4. **Documentation** (`8b28691`) - Added CLAUDE.md and comprehensive docs
-5. **HTML Viewer** (`52e08aa`) - Added self-contained HTML viewer for JSON output
+- **Claude Code**: Handled the core architecture decisions, error handling patterns, and CI/CD pipeline setup. Particularly valuable for getting the .csproj packaging configuration right on the first try.
+- **GitHub Copilot**: Excelled at generating repetitive code patterns, JSON serialization boilerplate, and regex text normalization functions.
+- **MCPs (Model Context Protocol)**: Provided seamless integration between different AI tools and development contexts, making the workflow feel natural rather than fragmented.
 
-Each iteration improved the tool's reliability and usability.
+**The Human-AI Partnership** 🤝
+
+The most interesting aspect wasn't that AI wrote the code, but how it changed the development process itself:
+
+1. **Design-First Thinking**: Instead of iterating through implementation details, I could focus on the user experience and data flow
+2. **Documentation-Driven Development**: Writing this blog post in parallel with coding helped clarify requirements and catch edge cases early
+3. **Confidence in Exploration**: Having AI assistance made it easy to try different approaches without the usual "sunk cost" feeling
+
+**Looking Forward** 🔮
+
+This project represents a new normal in software development - where the bottleneck shifts from typing code to thinking through problems and user needs. The combination of AI coding assistants, intelligent toolchains, and human creativity is genuinely transformative.
+
+For developers hesitant about AI tools: they're not replacing us, they're amplifying our ability to solve meaningful problems quickly. The future belongs to developers who can effectively collaborate with AI to build better software faster.
