# Name, voice and opening message Agent: name or rename your agent and change its avatar, choose its voice, set the top of the chat, write the opening message and reply buttons, and set the chat greeting. This is the Markdown version of https://www.meetdarwin.ai/help/agent/name-voice-and-opening, published by Darwin and generated on 27 October 2026. Find it in Darwin: Agent (https://app.meetdarwin.ai/admin/agent). Updated Oct 26, 2026. Select **Agent** in the sidebar to shape everything visitors see, from your agent's name to the chat's colors. This guide covers who your agent is and what it says first; [Make the chat look like your brand](https://www.meetdarwin.ai/help/agent/chat-appearance) covers colors, font and corners. The preview on the right shows each change straight away, and your website keeps the saved version until you select **Save changes**. _Screenshot: The Agent page with Agent selected in the sidebar: the Agent, Agent personality, Colors, Top of the chat and Opening message sections on the left, and the preview on the right showing the opening message, three reply buttons and the launcher._ 1. **Name your agent and add an avatar** Under **Agent**, type the **Name** (1) visitors see with every message. Beside **Avatar**, select **Upload image** (2) to add a picture shown beside each message: a PNG, JPG, WebP or SVG under 5 MB. Without one, the chat shows your agent's initials. **Launcher** (3) is the button visitors select to open the chat. **Default** shows your avatar, or the chat icon while there is no avatar. Choose **Custom** to upload an image just for the launcher. _Screenshot: The Agent section: Name set to Maya marked 1, Upload image beside Avatar marked 2, and the Launcher choice of Default or Custom marked 3._ 2. **Pick its voice** Under **Agent personality**, choose a **Voice**: **Friendly**, **Professional** or **Direct**. The voice changes how your agent words things, not what it does. _Screenshot: The Agent personality section with the Voice choice of Friendly, Professional or Direct highlighted._ 3. **Set the top of the chat** Under **Top of the chat**, write the short line under your agent's name in **Under the name** (1), up to 40 characters, such as "Replies instantly". **Button** (2) picks the button that stays in reach under the name: **Book a meeting**, one of your live [outcome forms](https://www.meetdarwin.ai/help/outcomes/build-an-outcome), or **No button**. _Screenshot: The Top of the chat section: Under the name reading Replies instantly marked 1, and Button set to Request a proposal marked 2._ Select the launcher in the preview to open the chat and see both under your agent's name. _Screenshot: The open chat in the preview: Maya with Replies instantly under the name marked 1 and the Request a proposal button marked 2, the first message, reply buttons and the message box._ 4. **Write the opening message** The opening message is the short card above the launcher that starts a conversation. Turn it on or off with the switch beside **Shown above the launcher** (1), then write it in **Message** (2), up to 120 characters. One question works best, for example "Comparing plans? I can tell you which one fits your team." _Screenshot: The Opening message section: the switch beside Shown above the launcher marked 1, and the Message box marked 2._ The preview shows it the way visitors see it, above the launcher, with your reply buttons under it. _Screenshot: The preview: Maya's opening message, What’s getting in the way of your next stage of growth?, with Explore services, See pricing and Book a meeting under it, above the launcher._ 5. **Add reply buttons** Reply buttons sit under the opening message so visitors can answer with one click. Under **Reply buttons**, select **Add a button** (2), then fill in the **Button label** and the **Message sent when clicked**. Select a button to edit it, or the bin beside it to remove it. You can have up to 4. Tick **Keep fixed in experiments** (1) for a button that must stay the same in every opening test. If Darwin is running opening tests, **Testing** under the reply buttons shows how many, with a **See tests** link. Pages in a test keep showing the test's opening until the test ends, so a page can show a different opening from the one you wrote here. _Screenshot: The Reply buttons section, 2 of 4, with Explore services open for editing: Button label, Message sent when clicked, Keep fixed in experiments marked 1, and Add a button marked 2._ 6. **Set the chat greeting** Under **Chat greeting**, write the **Greeting**: the first message people see when they open the chat. _Screenshot: The Chat greeting section with the Greeting field highlighted._ 7. **Save** Select **Save changes** in the bar at the bottom. **Discard** goes back to what is saved. If you changed the opening message, Darwin then asks what to do with running tests that started from your old opening: - **Use the new one in them** replaces the old opening in those tests. Their results start again from zero. - **Test old against new** keeps both openings in those tests, so they compete. - **Not now** leaves the tests as they are. Tests that use a page's own opening, rather than your site-wide one, aren't changed. _Screenshot: The bar at the bottom of the editor reading Unsaved changes · kept in this tab, with Discard and Save changes, Save changes highlighted._ ## Good to know - The opening message appears 2.5 seconds after the page loads. On a phone it also waits until the visitor has scrolled a quarter of the page or spent 10 seconds on it, whichever comes first. A personal link's greeting skips that wait. You can't change this timing. - A visitor who closes the opening doesn't see it again for the rest of their visit. To keep it off certain pages, use **Pages without the opening message** in [Settings → Agent](https://www.meetdarwin.ai/help/agent/agent-settings). - In a narrow window the preview moves behind a **Preview** button at the top of the page. - Darwin's sales behaviour is built in: it answers from what you give it in [Knowledge](https://www.meetdarwin.ai/help/knowledge/teach-your-agent), offers a meeting when a visitor shows interest, and doesn't make up prices, availability or bookings. - Unsaved changes are kept in this browser tab for up to 24 hours, even if you visit another screen. - [Make the chat look like your brand](https://www.meetdarwin.ai/help/agent/chat-appearance): Colors, font, corners, dark mode and sounds. - [Agent settings](https://www.meetdarwin.ai/help/agent/agent-settings): Turn your agent on or off, choose its domains and add a privacy notice.
