Composing a Message

The message input is a rich content-editable area that supports:

• Plain text — Just type and press Enter to send
• Rich formatting — Use the toolbar or Markdown shortcuts (see Formatting)
• File attachments — Click the paperclip or drag-and-drop files
• Emoji — Click the smiley face for the picker
• @mentions — Type @ followed by a name
• Slash commands — Type / for special commands (see Slash Commands)
• Scheduled send — Set a future date/time for delivery

​

Sending

Messages are delivered in real-time via Supabase Realtime. Other participants see your message instantly.

​

Optimistic Updates

When you send a message, it appears immediately in your view (optimistic update) before server confirmation. This makes the experience feel instantaneous. If the server request fails, the message is rolled back. The same applies to:

• Reactions — Appear instantly when you click
• Edits — Show immediately
• Deletes — Remove immediately

​

Message Grouping

Consecutive messages from the same person within a short time window are visually grouped:

• The first message shows the full avatar, name, and timestamp
• Subsequent messages appear without the header, creating a clean, chat-like flow

​

Editing a Message

You can edit your own messages after sending: Edited messages show an (edited) label after the timestamp.

​

Deleting a Message

You can delete your own messages:

1. Hover over your message
2. Click the trash icon in the hover toolbar
3. The message is removed immediately for everyone

​

Replying Inline

To reply to a specific message without starting a thread:

1. Hover over the target message
2. Click the reply arrow in the hover toolbar
3. A reply indicator appears above the input showing the original message text and sender
4. Type your reply and send
5. Click the X on the reply indicator to cancel

The reply appears in the main conversation with a visual reference to the original message.

​

Hover Action Toolbar

When you hover over any message, a toolbar appears with these actions:

​

@Mentions

Type @ followed by a team member’s name to mention them:

1. Type @ in the input
2. A dropdown appears with matching team members
3. Filter by typing more of the name
4. Click or press Enter to select
5. The mention appears as a highlighted tag

Mentioned users receive a notification.

​

Emoji Picker

Click the smiley face icon in the input toolbar to open the emoji picker. 16 commonly used emoji are shown for quick access: The standard set includes: thumbs up, heart, laugh, party, fire, eyes, check, 100, wave, think, clap, rocket, star-eyes, pray, peace, muscle. You can also use your OS emoji picker (Cmd+Ctrl+Space on Mac).

​

Scheduled Send

To schedule a message for later delivery:

1. Click the clock icon in the input toolbar
2. Select a date and time
3. Compose your message
4. Click Send — the message will be delivered at the scheduled time

Reference Cards

When you embed references via slash commands (/meeting, /vault, /todo, /brain), they appear as rich interactive cards in your message. These cards include:

• Meeting cards: Video thumbnail, participant avatars, date, and link
• Vault cards: File icon, name, type, size, and link
• Todo cards: Task title, status, priority, and link
• Brain cards: Conversation title, date, and link

Reference cards can be removed before sending by clicking the X on the card.
