# ChatAI Streamlit App (with Admin, OpenAI & Ollama)
A Streamlit app that provides:
- Rounded chat interface with **+** button to upload **files** or **images**
- Supports **OpenAI** and **Ollama** providers
- **Admin** role can manage user accounts
- Conversation history (SQLite)
- Export chat to Markdown
## Quickstart
1) **Create a virtual environment (recommended)**
```bash
python -m venv .venv
source .venv/bin/activate # On Windows: .venv\Scripts\activate
```
2) **Install dependencies**
```bash
pip install -r requirements.txt
```
3) **Run the app**
```bash
streamlit run app.py
```
4) **Login**
On first run, a default admin account is created:
- **username**: `admin`
- **password**: `admin123`
👉 Immediately change this in **Admin > Users**.
## Providers
- **OpenAI**: Set your key in the sidebar **(OpenAI API Key)** or via env var `OPENAI_API_KEY`.
- **Ollama**: Make sure Ollama is running locally (default endpoint `http://localhost:11434`).
You can change endpoint in the sidebar.
## Notes
- This is a reference implementation for local use. For production:
- Use a proper auth service (e.g., OAuth), secure key storage (e.g., Vault/KMS)
- Harden the admin endpoints and network access
- Add request limits, logging, and encryption-at-rest
