Most office workers probably know Slack as video conferencing and collaboration software – not least since working from home became more commonplace. Its focus is on business project and teamwork. To this end, it offers helpful features such as private messaging, group messaging, search filters, screen sharing, and file sharing. In the free license, Slack includes documentation of chat histories for past 10,000 messages. Since large companies need significantly more, the paid version is recommended in any case.
A central event feed keeps teams up to date, while files can be stored centrally for team members. A particularly practical feature is that third-party apps and business tools can be easily integrated into Slack. The @ function also allows users to be directly mentioned even when they are offline. Although Slack supports text chats as well as video and audio chats, the free version only offers 1-to-1 calls. In the paid version, up to 15 users can participate in the audio/video chat.
