Three ways to communicate

Organized conversations that keep context where it belongs.

Conversations that feel alive

Instant feedback with typing indicators, read receipts, and optimistic send.

Instant Send

Messages appear immediately with optimistic rendering — no loading spinners, no waiting.

Typing Indicators

See "{Name} is typing..." with animated dots when someone is composing a message.

Read Receipts

Tiny avatar circles show who has seen your messages — Messenger-style seen indicators.

Unread Badges

Sidebar count badge, channel-level indicators, and a branded favicon dot — never miss a message.

Rich message interactions

Threaded Replies

Reply to any message to start a thread. Keep conversations organized without flooding the main channel.

Emoji Reactions

React with emojis — one per person per message. Quick acknowledgments without cluttering the chat.

File Attachments

Drag and drop files into any conversation. 30+ supported file types including images, docs, and media.

Internal Messages

Mark messages as internal in shared channels. Agency staff only — clients never see them.

Edit & Delete

Edit your messages within 5 minutes. Delete anytime. Admins can delete any message.

Inline DM Search

Find anyone in your workspace instantly. Search filters channels and shows DM candidates as you type.
