# Demos, theme & history

## Demos tab

Choose the LiveDemos the agent can open. Publish them first (**Share → Public access**) so visitors can view them.

Click **Set default** on a demo to make it the one the agent opens first ("Default demo set").

Tips:

- Pick short, focused demos: one per feature or use case. The agent picks the right one for each question.
- Give demos clear names and step text. The agent uses them to choose.

## Theme

In **Settings → Theme**, choose **Light**, **Dark**, **Light blur** or **Dark blur** to match your website ("Theme saved").

## History

**Settings → History** lists the last 50 changes to the agent: persona edits, knowledge sources, demos and more.

To go back, click **Revert** on a change, then **Revert** again in "Revert to this point in history?". The agent is restored to that point.

For a quick undo, press `Ctrl/Cmd + Z` (redo with `Ctrl/Cmd + Shift + Z`) while you're not typing in a field.

## Session summary

**Settings → Session summary** sets when a session ends (5–60 minutes idle) and the [summary email](https://livedemo.ai/docs/ai-demo-agent/summary-emails/) template.
