If you're used to group chats for work, Slack might feel like one more app to manage. But it solves real problems that Signal or WhatsApp weren't designed for:
separate spaces per project or team
reply without spamming the whole group
colleagues see you're away before messaging
auto-quiet outside your working hours
limited find decisions from months ago
limited write now, send Monday morning
limited Asana, Google Drive, calendar…
reminders, standup bots, workflows
no mixing work and personal chats
Signal and WhatsApp are great for quick personal messages. Slack is designed for work: it keeps conversations organised, lets you set clear boundaries around your availability, and keeps work chat out of your personal phone.
If you're completely new to Slack, this video might be helpful to understand what Slack is and how it works:
Slack works in your browser, but the desktop app gives you better notifications and is generally faster.
Already have a Slack account from a previous or side job? No problem, you can be in multiple workspaces at the same time.
The mobile app is useful when you're away from your desk. After installing, go straight to the notification settings below (otherwise Slack will ping you for everything).
One of the biggest productivity killers is getting random notifications while you're deep in focus. to make Slack feel calm rather than overwhelming:

Useful features to know:
- Set your status - your colleagues see this before they write you, e.g.:
-
In a meeting -
Out sick -
Vacationing -
Working remotely - Use threads to organise discussions
- Schedule a message
- Save messages for later
- Slack has a number of built-in bots and apps that can save you time. A few worth knowing about:
- Every workspace has a built-in Slackbot . You can use it to set personal reminders — just type something like
/remind me to send the report tomorrow at 9am in any message box. It's also where Slack sends you automated notifications and onboarding tips. - Slack's built-in Workflow Builder lets you automate small recurring tasks — for example, posting a weekly check-in question to a channel, or sending a welcome message to new members automatically. No coding needed.
- When you connect tools like Asana or Google Calendar to Slack, they act as bots: they post updates directly into a channel so you don't have to switch apps to stay informed. Ask your workspace admin which integrations are already set up. You'll find all available apps and bots under in the r of Slack.
