PathNav

PathNav is a prototype Streamlit app that helps college students navigate syllabus accommodations, draft accommodation emails, and ask policy questions about ADA / Section 504.

What it does

• Scan syllabus PDFs and extract course details, deadlines, and accommodation language
• Let users enter courses manually if they don't have a PDF
• Review courses, requirements, and detected accommodation language
• Draft accommodation emails based on selected courses and student context
• Answer policy questions about ADA / Section 504 accommodations
• Walk through common accommodation situations step by step
• Store course data in Streamlit session state for use across tabs

Setup (Mac)

1. From the PathNav folder, create and activate a virtual environment:

   python3 -m venv .venv
   source .venv/bin/activate

2. Install dependencies:

   pip install -r requirements.txt

3. Add your Anthropic API key. Copy the example secrets file and paste your key:

   cp .streamlit/secrets.toml.example .streamlit/secrets.toml

   Then edit .streamlit/secrets.toml. You can also export it in your shell instead:

   export ANTHROPIC_API_KEY=your_api_key_here

   Do not commit .streamlit/secrets.toml or .env.

4. Run the app:

   streamlit run app.py

   Then open http://localhost:8501

On Streamlit Community Cloud, set ANTHROPIC_API_KEY in the app's Secrets settings instead of committing a secrets file.

Notes

• app.py mounts five tabs: Syllabus Scanner, Table of Contents, Email Draft, Policy Q&A, and Navigator
• utils/api_client.py is the backend wrapper (PDF parsing + Claude Messages API, model claude-sonnet-5)
• components/ contains the Streamlit tab pages
• utils/session_state.py defines the shared Streamlit state keys
• Navigator and Table of Contents work without an API key; Scanner, Email Draft, and Policy Q&A need one
