What is Slack?

Slack is a messaging platform for work. It brings team communication and collaboration into one place. Slack has chat rooms, private groups, and direct messaging. You can upload files and integrate Slack with many other apps. There are browser and mobile versions and a Slack desktop app.

How to use Slack in Sidekick?

You don’t have to download Slack desktop app to use it in Sidekick. It’s easy as ABC: click Add Application, pick Gmail, and log in with your current account.

Benefits of using Slack in Sidekick

We see the future of online work in using not desktop apps but web versions and integrating them into a browser. This gives you better control of your virtual work environment, saves your time, and helps to retain your focus. There are numerous advantages in fusing Slack and Sidekick compared to Slack desktop app.

Save resources

  • Memory-wise, integration with Sidekick is a better choice if your desktop app size is more than 100MB.
  • Any document or tab launched in Chromium needs an isolated computing process to run. It leads to excessive memory consumption. Sidekick uses one framework to run similar processes. It significantly frees up computing power and takes multitasking to a new level.
  • Save even more memory with Sidekick’s AI-based tab-suspender that analyzes and offloads unused tabs.

Sidebar integration

  • You can access Slack directly from your Sidebar. It keeps Slack at your fingertips and your tab strip free of clutter while Slack desktop app consumes more resources.
  • You can also access it by using a keyboard shortcut Option-N, where N is the position of Slack in your Sidebar.
  • Sidekick will display unread notifications on Slack icon.

Support for multiple accounts

Right-click on Slack icon and add as many accounts as you wish. You can be logged into all of your accounts at the same time or you can easily switch between them.


  • Right-click on Slack icon to search through recent documents or to open our Global Search feature (Option-F) to search through all Slack documents.
  • Type Slack in your search query to filter results. Open the file in a new tab or just copy a link, everything from one handy window.

Split view

Click Slack while holding Option key to open it in split view. Work with Slack and your other documents or apps side-by-side like never before.
