Negotiate With AI – Hack Reddit 2025 Submission

Inspiration

I’ve always been fascinated by how characters navigate high-stakes situations in movies and TV shows. Often, I imagine how I would handle those moments differently. This inspired me to create a game where players test their negotiation skills in intense AI-generated scenarios.

At the same time, I didn’t want a predictable experience where you hear the same scripted dialogues. Instead, I built a dynamic AI-driven system that generates unique scenarios based on 300 different themes, some inspired by movies. This ensures an ever-evolving challenge where no two negotiations are alike—offering endless debates and arguments to tackle.

What It Does

Negotiate With AI is a text-based negotiation game where players must persuade an AI-controlled villain within a limited number of messages. The AI evaluates how well the player negotiates and provides feedback on their persuasion and decision-making skills.

Gameplay Flow:

1. Starting a Game:
   
   • AI generates a random negotiation scenario, a unique villain, and an opening message.
     
2. User Sends Up to 5 Messages:
   
   • Each message has a character limit, adding to the challenge.
     
   • The AI villain dynamically responds (4 times).
     
3. Final Verdict:
   
   • AI evaluates the negotiation and determines success or failure.
     
   • AI provides feedback on the user’s persuasion skills.
     
4. Sharing on Reddit:
   
   • Players can post their results on Reddit for others to vote on the best strategies.
     

How We Built It

Core Technologies:

• Google Gemini AI – Generates scenarios, villain responses, and evaluates negotiation success.
  
• Reddit’s Devvit API – Handles interactive posts and automation.
  
• JavaScript/TypeScript – Powers the game logic and AI interactions.
  

Development Process:

1. Set Up Environment – Configured Devvit API, Gemini AI, and defined the storage structure.
   
2. AI Scenario Generation – Created dynamic AI prompts for generating unique scenarios.
   
3. Negotiation Logic – Developed AI villain responses and implemented win/loss conditions.
   
4. Reddit Integration – Automated the posting of game results.
   
5. User Experience Improvements – Added restart functionality, character limits, and adaptable AI responses.
   
6. Testing & Debugging – Fine-tuned AI prompts, optimized response logic, and improved Reddit post formatting.
   

Challenges We Ran Into

1. Devvit Limitations – Learning the constraints of Reddit’s Devvit API took time.
   
2. SVG Issues – Devvit blocks only support SVGs, but embedding them didn’t work as expected.
   
3. Switching to Devvit WebView – Since images weren’t working, I moved the game to Devvit WebView, a framework I had never used before. Fortunately, the documentation helped.
   
4. AI Integration with WebView – Connecting Gemini AI while ensuring secure secret storage was a major challenge.
   

Accomplishments That We're Proud Of

• Successfully built a fully interactive AI-powered negotiation game in a short timeframe.
  
• Overcame Devvit WebView challenges and created a smooth player experience.
  
• Implemented a dynamic scenario system, ensuring infinite replayability.
  
• Integrated Reddit community engagement, allowing players to share and discuss their negotiation results.
  

What We Learned

• How to leverage Gemini AI for scenario-based storytelling.
  
• How to navigate the Devvit API and its limitations.
  
• The power of WebView for creating more flexible Reddit applications.
  
• Best practices for handling AI-generated content within interactive experiences.
  

What's Next for Negotiate With AI

To enhance the game further, I plan to add:

• Scenario Sharing & Competitive Mode:

  • Players can play each other’s past scenarios and compare their negotiation skills.
    

• Daily AI-Generated Scenarios:

  • Instead of only posting games played by users, an AI-generated negotiation scenario will be posted daily. This will encourage community-wide discussions and strategy sharing.
    

• Gamification & Leaderboards:

  • Players will earn points for successful negotiations and see their ranking on a leaderboard.
    

• Multiplayer Mode:

  • Users will be able to team up and negotiate together.
    

• Role-Based Play:

  • Players can switch roles and take on the villain’s perspective, testing their ability to resist persuasion.
    

🚀 This is just the beginning! Excited to see where this project goes next. 🎉
