Content & messaging

Everything is configured per agent in Web channel settings → Configure:

Greeting — the short headline on the home screen (e.g. "Hi 👋").
Welcome message — the paragraph under the greeting.
Starter chips — one-tap suggested questions (one per line); tapping sends it as a message.
Input placeholder — the hint inside the empty message box.
Reply time — a soft "usually replies in ~5 min" note.

Changes apply to every site using that agent's key — no need to touch the embed code.

Branding & button style

Avatar — image URL, an iconify name (e.g. lucide:bot), or an emoji.
Primary colour — accent colour for the button and bubbles. (Tip: also set data-color on the script tag so the button paints instantly before the chat loads.)
Cover image — hero image at the top of the open chat, or keep the default gradient.
Button style (FAB) — round (classic bubble) or pill (a wider button with avatar + agent name that auto-collapses). Pill drives more first messages on marketing pages.
Hide "Powered by Flutch" — toggle the footer attribution.
