# Agent and chat preferences
> Choose how chats look and notify you, what your agents can reach, how follow-up messages behave and how Claude Code and Codex answer.
Set how Wonder Chat works for you: tabs, sounds and notifications in **Settings > Preferences**, and what your agents can use and how they answer in **Settings > Agents**. These settings are kept on this computer, except the switches in Preferences > Advanced, which follow your account.
**Before you start** · Desktop app · Free plan
## Get notified when a chat finishes
In **Settings > Preferences > Notifications**:
| Setting | What it does | Default |
| - | - | - |
| **When a chat finishes** | The sound Wonder plays when a chat finishes. Pick **None**, one of the built-in sounds (**Chime**, **Bell**, **Marimba**, **Crystal**, **Rise** or **Droplet**), or **Choose an MP3 file** to use your own. Wonder plays a sound when you pick it. | **Chime** |
| **Desktop notifications** | Alerts when a chat finishes or needs you, for example to approve something or answer a question. | On |
Your own sound must be an MP3 of 2 MB or less that plays for 10 seconds or less. Once you've added one, it's listed as **Your MP3**.
## Change how chats show in the app
In **Settings > Preferences > Advanced**:
| Setting | What it does |
| - | - |
| **Chat tabs** | Open several chats in a worktree as tabs. |
| **Line changes in sidebar** | Show lines added and removed per worktree. |
| **Open the side panel on the pull request** | Show the pull request instead of its changes. |
| **Attach selection to chat** | What you select on the canvas is added to your message. See [Add to chat from the canvas](https://wonder.design/docs/add-to-chat-from-the-canvas.md#attach-what-you-select-automatically). |
**Attach selection to chat** is on by default. The other three start on if you picked **Developer** for "What best describes you?" when you set up the desktop app, and off otherwise.
## Choose what your agents can use
**Settings > Agents > Access** has a switch for each extra your agents can use. Changes apply when a chat's agent next starts. Claude rows show once you've signed in to Claude Code, and Codex rows once you've signed in to Codex.
| Setting | What it does | Default |
| - | - | - |
| **Share memory between your agents** | Each chat sees what your other agents remember. See [Memory and design preferences](https://wonder.design/docs/memory-and-design-preferences.md#share-memory-between-your-agents). | On |
| **Claude connectors** | Use your claude.ai connectors in Claude chats. | On |
| **Claude artifacts** | Read, publish and update artifacts through your Claude account. | On |
| **Use Chrome in Claude chats** | Lets Claude use Chrome through the Claude in Chrome extension. | Off |
| **ChatGPT apps in Codex chats** | Use your ChatGPT apps in Codex chats. | On |
| **Computer Use in Codex chats** | Let Codex use the apps on your computer. | Off |
### Use Chrome in Claude chats
1. Click **Get the Claude in Chrome extension** under the setting and install it in Chrome.
2. Make sure Claude Code is signed in with your Claude plan, not an API key or a cloud provider.
3. Turn on **Use Chrome in Claude chats**, then start a new chat.
## Choose what a message sent mid-task does
**Follow-up messages**, in **Settings > Agents > Chat**, decides what happens when you send a message while the agent is still working:
* **Queue** (the default): your message waits until the agent is done, then goes next.
* **Steer**: your message joins the current work, so the agent takes it into account straight away.
Press ⌘ ↵ to send one message the other way. The change applies to your next message.
## Expand agent work by default
Turn on **Expand agent work by default**, in **Settings > Agents > Chat**, to see an agent's thinking and tool calls unfolded instead of collapsed. It's off by default, and applies at once to every fold you haven't opened or closed yourself.
## Choose how your agent answers
In **Settings > Agents > Response preferences**:
* **Claude response style**: the style Claude chats answer in. It applies from the next message.
* **Use my Claude Code setting** (the default) keeps whatever your Claude Code settings choose.
* Claude Code's styles: **Default**, **Proactive** (starts work without routine questions), **Concise** (results first, without narration), **Explanatory** (adds short Insight notes on its choices) and **Learning** (leaves small pieces for you to write).
* Under **Your styles**, any output style of your own that a Claude chat has listed.
* **Codex personality**: **Default** keeps Codex's own personality, and **None** turns personality off. It applies to new chats.
## If something goes wrong
* **A setting isn't in Settings > Agents.** Rows for Claude Code or Codex show only while that agent is signed in. Sign in under **Provider accounts** at the top of **Settings > Agents**.
* **"Chrome needs a Claude plan sign-in, and this computer's Claude login uses an API key or a cloud provider."** Claude in Chrome works only with a Claude plan. Sign in to Claude Code with your Claude account, then try again.
* **A changed switch doesn't take effect in an open chat.** Access settings apply when the chat's agent next starts. Start a new chat to use them straight away.
* **"That file isn't an MP3", "That MP3 is too big" or "That sound is too long".** Choose an MP3 of 2 MB or less that plays for 10 seconds or less.
