📚 Comparison with existing products

📀 Quick Start - Installation via Docker

  1. Create a new .env file

    cp .env.example .env
    

    Paste your API keys in .env file. A single ReByte or OpenAI API key is enough to get started.

    You can also configure other API keys if you have them.

  2. Start the app with docker-compose.yaml

    docker compose up
    

    If you have issues with docker (especially on a non-Linux machine), please refer to https://docs.docker.com/get-docker/ (installation) and https://docs.docker.com/desktop/troubleshoot/overview/ (troubleshooting).

  3. Open http://localhost:3000 and enjoy the app!

💿 Developers - Installation via Python

  • Step 1. Clone the repo

    git clone https://github.com/Shaunwei/RealChar.git && cd RealChar
    
  • Step 2. Install requirements

    Install portaudio and ffmpeg for audio

    # for mac
    brew install portaudio
    brew install ffmpeg
    
    # for ubuntu
    sudo apt update
    sudo apt install portaudio19-dev
    sudo apt install ffmpeg
    

    Note:

    • ffmpeg>=4.4 is needed to work with torchaudio>=2.1.0

    • Mac users may need to add ffmpeg library path to DYLD_LIBRARY_PATH for torchaudio to work:

      export DYLD_LIBRARY_PATH=/opt/homebrew/lib:$DYLD_LIBRARY_PATH
      

    Then install all python requirements

    pip install -r requirements.txt
    

    If you need a faster local speech to text, install whisperX

    pip install git+https://github.com/m-bain/whisperx.git
    
  • Step 3. Create an empty sqlite database if you have not done so before

    sqlite3 test.db "VACUUM;"
    
  • Step 4. Run db upgrade

    alembic upgrade head
    

    This ensures your database schema is up to date. Please run this after every time you pull the main branch.

  • Step 5. Setup .env:

    cp .env.example .env
    

    Update API keys and configs following the instructions in the .env file.

    Note that some features require a working login system. You can get your own OAuth2 login for free with Firebase if needed. To enable, set USE_AUTH to true and fill in the FIREBASE_CONFIG_PATH field. Also fill in Firebase configs in client/next-web/.env.

  • Step 6. Run backend server with cli.py or use uvicorn directly

    python cli.py run-uvicorn
    # or
    uvicorn realtime_ai_character.main:app
    
  • Step 7. Run frontend client:

    • web client:

      Create an .env file under client/next-web/

      cp client/next-web/.env.example client/next-web/.env
      

      Adjust .env according to the instruction in client/next-web/README.md.

      Start the frontend server:

      python cli.py next-web-dev
      # or
      cd client/next-web && npm run dev
      # or
      cd client/next-web && npm run build && npm run start
      

      After running these commands, a local development server will start, and your default web browser will open a new tab/window pointing to this server (usually http://localhost:3000).

    • (Optional) Terminal client:

      Run the following command in your terminal

      python client/cli.py
      
    • (Optional) mobile client:

      open client/mobile/ios/rac/rac.xcodeproj/project.pbxproj in Xcode and run the app

  • Step 8. Select one character to talk to, then start talking. Use GPT4 for better conversation and Wear headphone for best audio(avoid echo)

Note if you want to remotely connect to a RealChar server, SSL set up is required to establish the audio connection.

🆕! Anyscale and LangSmith integration

👇click me

Anyscale

You can now use Anyscale Endpoint to serve Llama-2 models in your RealChar easily! Simply register an account with Anyscale Endpoint. Once you get the API key, set this environment variable in your .env file:

ANYSCALE_ENDPOINT_API_KEY=<your API Key>

By default, we show the largest servable Llama-2 model (70B) in the Web UI. You can change the model name (meta-llama/Llama-2-70b-chat-hf) to other models, e.g. 13b or 7b versions.

LangSmith

If you have access to LangSmith, you can edit these environment variables to enable:

LANGCHAIN_TRACING_V2=false # default off
LANGCHAIN_ENDPOINT=https://api.smith.langchain.com
LANGCHAIN_API_KEY=YOUR_LANGCHAIN_API_KEY
LANGCHAIN_PROJECT=YOUR_LANGCHAIN_PROJECT

And it should work out of the box.


📍 Roadmap

  • Launch v0.0.4
  • Create a new character via web UI
  • Lower conversation latency
  • Support Twilio
  • Support ReByte
