LawGlance - Tutorial

Ready to get started? Follow these simple steps to set up LawGlance on your machine:

1. Clone the Repository 🌀

   git clone https://github.com/lawglance/lawglance.git

2. Install uv 📂

   First, let’s install uv and set up our Python project and environment

   MacOS/Linux:

   curl -LsSf https://astral.sh/uv/install.sh | sh

   Windows:

   powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

   Make sure to restart your terminal afterwards to ensure that the uv command gets picked up.

3. Install Dependencies 📦

   uv sync

4. Set Your OpenAI API Key 🔑

   Open .env and add your OpenAI API key:

   OPENAI_API_KEY=your-api-key-here

5. Run the Application 🚀

   uv run streamlit run app.py

6. Access the App 🌐
   Open your browser and visit:

   http://127.0.0.1:8501

LawGlance is now powered by an agentic retrieval pipeline built with LangGraph, living in the backend/ folder. Instead of a single fixed RAG chain, the agent decides for itself when to call the retrieve_docs tool, loops until it has enough context, and only then produces a cited final answer.

• backend/graph.py / backend/nodes.py — the LangGraph agent loop (llm_call → tool_node → final_answer)
• backend/tools.py — the vector-store retrieval tool the agent can call
• backend/retrieval.py — agent_invoke(), the entry point the Streamlit app (app.py) now calls
• backend/main.py — an optional FastAPI HTTP API in front of the same agent

The original single-chain implementation (lawglance_main.py, chains.py) is still in the repo for reference and is not deleted, but it's no longer what app.py runs against.

Run the FastAPI backend standalone (useful for integrating LawGlance into another app):

uv run uvicorn backend.main:app --reload

Then query it directly:

curl "http://127.0.0.1:8000/query?query=What+is+Article+21%3F"

LawGlance uses Redis to cache chat history and LLM responses for faster, scalable performance.

1. Install Redis Server

   Ubuntu/Linux:

    sudo apt-get update
    sudo apt-get install redis-server

   MacOS (with Homebrew):

   brew install redis

   Windows (Recommended: Use WSL - Windows Subsystem for Linux):

   1. Install WSL and set up a Linux distribution (e.g., Ubuntu).
   2. Inside the WSL terminal, run:

      sudo apt-get update
      sudo apt-get install redis-server

   3. Start the Redis server:

      redis-server

2. Start Redis Server

   redis-server

3. Verify Redis is Running

   redis-cli ping

   You should see: PONG

4. No Additional Python Setup Needed

• The LawGlance backend automatically connects to Redis at redis://localhost:6379/0.
• If you want to use a different host or port, update the redis_url parameter in your code. Redis caching is optional for local development but highly recommended for production deployments to ensure fast and reliable chat experiences.
