Mentions & Notifications
@mention teammates inside documents and conversations to bring their attention to specific content, and receive notifications when you're mentioned or when something you care about changes.
Overview
Mentions let you address a specific person directly inside a brief, document, or conversation by typing their name with the @ symbol. The person you mention receives a notification so they know exactly where to look. Notifications also surface other account-level updates — keeping the team informed without requiring constant manual check-ins.
Use mentions when you want a particular teammate to review a section, respond to a question, or take an action on something you've written.
How It Works
-
Trigger the mention picker — While editing a brief, document, or conversation, type
@followed by any part of a teammate's name or email address. A picker appears showing matching team members (up to 10 results). -
Select the person — Use the arrow keys to navigate the list and press Enter, or click the name directly. The mention is inserted as a styled tag in the content.
-
Notification is created — The mentioned person receives an in-app notification with the full conversation context — the message containing the mention and the surrounding thread — so they understand why they were mentioned before clicking through. If instant notifications are enabled for your workspace, it appears immediately; otherwise on their next page load.
-
They're added as a participant — When you mention someone in a conversation, they're automatically added as a participant on that thread. This keeps them in the loop for future messages without a separate invite step.
-
Notification is read or dismissed — The recipient can mark notifications as read (removes the unread badge but keeps the item visible) or dismiss them (removes from view entirely). Notifications expire automatically after one month.
Key Capabilities
-
Mention team members and the AI assistant: The @mention picker includes all team members plus the Hamster AI assistant. Direct a question or task at the AI the same way you would a human teammate.
-
Full thread context in notifications: When you receive a mention notification, it includes the surrounding conversation — not just the single message. You can read the thread and understand why you were mentioned before clicking through.
-
Automatic participant addition: Mentioning someone in a conversation thread automatically adds them as a participant. They see the thread in their workspace and receive future updates from it.
-
Filtered search: The picker filters results by name or email as you type, so you can find the right person quickly in large teams.
-
Keyboard navigation: Arrow keys move through the list, Enter confirms, Escape cancels — no mouse required.
-
In-app notification center: Notifications accumulate in a popover accessible from the top navigation. An unread count badge indicates new items.
-
Read and dismiss separately: Reading a notification clears the unread count but keeps it in the list for reference. Dismissing removes it entirely.
-
Workspace notifications: Notifications are tied to your workspace. Members of the same workspace see notifications relevant to shared work.
Notification Types
| Type | When it appears |
|---|---|
| Info | Standard updates and mentions |
| Warning | Situations that may need attention |
| Error | Actions that failed or require follow-up |
Notifications are delivered in-app by default. Real-time delivery (instant push to open browser sessions) is a separate configuration option — see your workspace settings.
Workspace Configuration
Notifications can be turned on or off at the workspace level:
- Notifications: Controls whether the notification center appears. On by default.
- Real-time notifications: Controls whether notifications push instantly to open sessions. Off by default; when disabled, notifications appear on your next page load.
Contact your workspace administrator to change these settings.
Tips
- You can mention the Hamster AI assistant with @Hamster to assign it a question or task inline. This is useful when you want to flag something for AI follow-up without leaving the document.
- Dismissed notifications are gone permanently. If you want to preserve a notification for later reference, mark it as read instead.
- Notifications expire after 30 days and are removed automatically. For important action items, use a task instead of relying on notifications for long-term tracking.
- The mention picker only shows people who are members of the current team account. You cannot mention someone outside your workspace.
