Slack brings team communication and collaboration into one place so you can get more work done, whether you belong to a large enterprise or a small business. Check off your to-do list and move your projects forward by bringing the right people, conversations, tools, and information you need together. Slack is available on any device, so you can find and access your team and your work, whether you’re at your desk or on the go.

Use Slack to:
• Communicate with your team and organize your conversations by topics, projects, or anything else that matters to your work
• Message or call any person or group within your team
• Share and edit documents and collaborate with the right people all in Slack
• Integrate into your workflow, the tools and services you already use including Google Drive, Salesforce, Dropbox, Asana, Twitter, Zendesk, and more
• Easily search a central knowledge base that automatically indexes and archives your team’s past conversations and files
• Customize your notifications so you stay focused on what matters

Scientifically proven (or at least rumored) to make your working life simpler, more pleasant, and more productive. We hope you’ll give Slack a try.

What's New

Version 3.52

• When you set your status, you can now also set a time (or date) for it to expire. No longer will people question how you're "Working remotely on Tuesday" when it's Thursday, or wonder why you've been "At the dentist" for 19 consecutive hours.
• Fixed: If someone else changed their status while your app was offline, we would sometimes still show the old status after you came back online. This was confusing for everyone, frankly. Thankfully, it no longer happens.

Editors' Notes

Keep every team project under control, no matter its size.

Ruddy marvellous


Our IT manager introduced this to our office a while ago and it’s totally changed the way we communicate across 5 offices. Hardly any internal emails, sett your notifications to reduce noise, see what you need to see! You can set up group channels like social, announcements etc, private channels with only certain staff included (like management) and other temporary ones for organising things like surprise birthday parties! Brilliant. Get it. Look at the help pages to get you set up. You won’t regret it. We use a paid version now for the company but the free one is great to get you started.

Very productive


Had never heard of Slack before until someone at work introduced it as a single method of communication between multiple companies. Previously we were bogged down with hundreds of emails and trying to use WhatsApp, as we all work for different companies so have no common method of communicating. If you’ve ever used Discord it works very much the same way - can create rooms within your lobby, send attachments etc. Would recommend it to anyone who needs to manage any number of people across various locations
