### Why have a local (Institution) chat?

### Privacy & Data Use

Your chat prompts and responses are recorded so we can improve the platform. **Please do not paste credentials, tokens, or personal passwords.** Some important things to consider:

- **Recorded:** We store chat prompts for usage analytics for quality, security, and capacity planning.
- **No History:** We use temporary guest accounts, meaning your chat history is not saved. Once you leave this page, your previous conversations will be gone.
- **Research data:** We do not use or analyze your scientific datasets. You may discuss patient-sensitive or confidential topics because the service runs entirely inside the Douglas network.
- **Future billing:** The service is free in beta, and will become paid later.
- **API access:** Disabled by default, it is only available to authorized projects.
- **Private chat account:** Should you require your own private chat (with history), please contact us detailing the specifics.

### Open WebUI Quick Start Usage

1. Start a new chat by clicking the **New chat** button (top left pane).
2. **Select a model** from the drop-down list (top centre of the chat window).
3. Ask one thing at a time using short, specific prompts.
4. Provide context for the chat by describing your task or **attaching files**.
5. Toggle the **web search** integration on/off depending on if your model needs it.
6. Iterate. If the answer isn’t right, ask it to try again (e.g. "Simplify and summarize it in 100 words").
