AI Alibis: Multi-Agent LLM Murder Mystery

Play online

Setup

1. Git clone the repo

   git clone https://github.com/ironman5366/ai-murder-mystery-hackathon.git
   cd ai-murder-mystery-hackathon

2. Add your Anthropic API to api/.env file (optionally can export conversations to postgres with DB_CONN_URL="postgresql://link_to_db_conn")

   nano api/.env
   export ANTHROPIC_API_KEY="YOUR_API_KEY_HERE"
   (<ctrl+x , y, enter> to save changes and exit nano)

3. Install Node dependencies

   web/npm i

4. Start up the api

   bash api_start.sh

5. In separate terminal, start up the web interface

   bash web_start.sh

6. Play the game!

Setup (with Docker)

1. Git clone the repo

git clone https://github.com/ironman5366/ai-murder-mystery-hackathon.git
cd ai-murder-mystery-hackathon

2. Set environment variables:

export ANTHROPIC_API_KEY="YOUR_API_KEY_HERE"

3. Open a terminal in the folder containing this README, then run:

docker compose up

This should start three containers (the database, Python API, and React frontend) and create a persistent volume for the database.

4. Play the game at http://localhost:3000/

If you change any files (for example, changing the Anthropic model in /api/settings.py), then you will likely need to rebuild the images:

docker compose up --build

5. To shut everything down, hit CTRL-C or click the stop button in the Docker GUI.

To clean up, use the Docker GUI to delete all containers then go to the "Volumes" tab to delete the associated database volume.
