+# Gmail RAG Assistant 📧
+
+Search and ask questions about your Gmail emails using AI.
+
+## Setup
+
+### 1. Install Dependencies
+
+```bash
+python -m venv .venv
+source .venv/bin/activate  # Windows: .venv\Scripts\activate
+pip install -r requirements.txt
+```
+
+### 2. Google Cloud Setup
+
+1. Go to [Google Cloud Console](https://console.cloud.google.com)
+2. Create a project and enable **Gmail API**
+3. Create **OAuth 2.0 Desktop Client** credentials
+4. Download and save as `~/.config/gcp/langchain/credentials.json`
+5. Add your email as a test user in OAuth consent screen
+
+### 3. Configure Environment
+
+Create `.env` file:
+
+```env
+GOOGLE_CREDENTIALS_PATH=~/.config/gcp/langchain/credentials.json
+GOOGLE_TOKEN_PATH=~/.config/gcp/langchain/token.json
+OPENAI_API_KEY=your_openai_api_key_here
+```
+
+Get OpenAI API key from [platform.openai.com](https://platform.openai.com/api-keys)
+
+## Usage
+
+### Index your emails:
+```bash
+python ingest_gmail_drive.py
+```
+
+### Launch UI:
+```bash
+python app.py
+```
+
+Open `http://localhost:7860` in your browser.
+
+## File Structure
+
+```
+gmail_rag/
+├── ingest_gmail_drive.py  # Fetch and index emails
+├── app.py                 # Gradio UI
+├── requirements.txt       # Dependencies
+├── .env                   # API keys (create this)
+└── chroma/               # Vector database (auto-created)
+```
+
+## Configuration
+
+**Change number of emails** in `ingest_gmail_drive.py`:
+```python
+gmail_docs = load_gmail(n=100)  # Adjust this number
+```
+
+**Change AI model** in `app.py`:
+```python
+LLM_MODEL = "gpt-4o-mini"  # or "gpt-4", "gpt-3.5-turbo"
+```
+
+## Troubleshooting
+
+- **"Access Blocked"**: Add your email as test user in Google Cloud
+- **"ChromaDB not found"**: Run `ingest_gmail_drive.py` first
+- **Token expired**: Delete `~/.config/gcp/langchain/token.json` and re-run
+
+## Cost
+
+- Embeddings: ~$0.01-0.05 per 100 emails
+- Queries: ~$0.01 per 100 questions (using gpt-4o-mini)
+- Gmail API: Free
+
+## Security
+
+Never commit: `.env`, `credentials.json`, `token.json`, `chroma/`
+
+The `.gitignore` file protects these automatically.
