Most teams customize four things: the launcher color, the launcher position, the welcome message, and the team avatar. All four live in Settings > Widget > Appearance.
Colors
Pick a primary color (auto-matched to your brand by the AI if you upload a logo) and a foreground color. We auto-compute hover, focus, and active states. WCAG 2.2 AA contrast is enforced.
Position
Bottom-right (default), bottom-left, top-right, top-left. Offset in pixels from the edge, configurable per breakpoint.
Welcome message
The first message a visitor sees when they open the chat. Personalize with variables (visitor first name if known, page they are on, time of day).
