# Messages: name, voice and opening

Agent Studio → Messages: name your agent, choose its voice and tone, write the opening message above the chat button, add reply buttons and set the chat greeting.

This is the Markdown version of https://www.meetdarwin.ai/help/agent-studio/name-voice-and-opening, published by Darwin and generated on 23 October 2026.

Find it in Darwin: Agent Studio → Messages (https://app.meetdarwin.ai/admin/agent?tab=design). Updated Oct 13, 2026.

Messages holds everything your agent says before and at the start of a chat. The preview on the right shows each change straight away.

1. **Name your agent and pick its voice**

   Under **Name and voice**, type the **Agent name** visitors see in the chat. Then open **Voice & tone** and choose **Friendly**, **Professional** or **Direct**. The tone changes how the agent words things, not what it does.

2. **Write the opening message**

   The opening message is the short card above the chat button that starts a conversation. Turn it on or off with the switch (1), then write it in **Message above the chat button** (2). One question works best, for example "Comparing plans? I can tell you which one fits your team."

   If Darwin is running opening tests, the screen says so. 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. Select **See tests** to check.

3. **Add reply buttons**

   Reply buttons sit under the opening message so visitors can answer with one click. Select **Add button** (1) for a new one, or select a button to edit its **Button label** and the **Message sent when clicked**. You can have up to 4.

   Tick **Keep fixed in experiments** (2) for a button that must stay the same in every opening test.

4. **Set the chat greeting**

   Under **Chat greeting**, write the first message people see when they open the chat.

5. **Save**

   Select **Save changes**. **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. Its 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.

## 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 40% of the way down. 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 **Hide on these pages** on the [Visibility & privacy](https://www.meetdarwin.ai/help/agent-studio/visibility-and-privacy) tab.
- The opening can be up to 120 characters, the same limit opening tests use. Shorter is better: one question works best.
- Darwin's sales behaviour is built in: it answers questions from your [knowledge](https://www.meetdarwin.ai/help/agent-studio/teach-your-agent), offers a meeting when a visitor shows interest, and doesn't make up prices, availability or bookings.

- [Teach your agent: knowledge](https://www.meetdarwin.ai/help/agent-studio/teach-your-agent): The pages, documents and business context your agent answers from.
- [Visibility and privacy](https://www.meetdarwin.ai/help/agent-studio/visibility-and-privacy): Where the chat runs, where the opening is hidden, and a consent line.
