Slack
The default office chat. Channels instead of one giant inbox.
What it is
Slack is workplace chat: channels, DMs, huddles, and a long list of integrations. Free workspaces keep a limited history. Paid plans search the full archive and add Slack Connect. Use it for work. Use Discord or Telegram if the group is not a company.
