Inspiration

Going live alone is hard.
While talking, you’re expected to change camera angles, show slides, add captions, and keep viewers engaged—all at once. I wanted a buddy who could handle the production booth, so every solo creator can focus on the story, not the buttons.

What it does

Presentation Buddy is an AI-powered sidekick for streamers and presenters.
It listens to what’s happening on screen and behind the mic, then:

• Switches scenes at the perfect moment
  
• Pops up captions, graphics, or picture-in-picture window automatically
  
• Even delivers short voice-overs when you need a break
  

Think of it as a tiny producer that never gets tired.

How I built it

• Claude AI listens for cues.
  
• A lightweight relay sends those cues to OBS Studio, the most popular live-stream tool.
  
• OBS takes the commands—“change camera,” “show caption,” “start replay”—and makes the magic happen.
  
• A sprinkle of text-to-speech gives the AI its own voice.

All of this runs locally, so there’s no cloud delay or fancy hardware.

Challenges I ran into

• Build a MCP server wrapping the native OBS APIs
• Real-time speech response time
• Good plot that Claude follows well
• I could not make it providing screenshot to claude via MCP

Accomplishments that we're proud of

• A live demo that goes from title slide to dynamic content with zero human clicks.
  
• Turned a one-person setup into a stress-free broadcast.
  

What I learned

• How to buid and configure MCP on Claude and Cursor
