Slack

Team messaging in organised channels

Slack is a business communication app for teams that need to keep conversations separated by project, department, or subject. Instead of placing every discussion in one inbox, it uses dedicated channels so members can follow the work relevant to them. Messages remain searchable, making it easier to return to earlier decisions, files, and replies.

Ways to collaborate

Alongside written messages, Slack supports quick voice and video conversations through huddles, as well as clips for sharing information asynchronously. These options suit teams that need to explain an issue, discuss a task, or provide an update without arranging a full meeting. Threads help keep replies connected to the original message rather than interrupting the wider channel.

Connected work tools

The app can connect with a broad range of workplace services, including Salesforce, Google Drive, and Asana. These integrations are intended to keep updates and approvals closer to the conversations where work is already being discussed. Slack also includes canvases for shared documents and project notes, giving teams another place to organise information alongside their messages.

What users should know

Slack is a good fit for companies, project groups, and distributed teams that need a central place for ongoing communication. Its many channels, notifications, integrations, and collaboration features may take some time for new users to understand, especially in larger workspaces. The app is listed in the Business category and is developed by SLACK TECHNOLOGIES L.L.C. It has a 4.66 rating from more than 175,000 reviews and records 10,000,000+ installs.
