Slack excels as a tool for team members. However, that doesn't mean that it can't be used for soloists as well. Some people find that Slack works well as a personal assistant. Slack has a built-in assistant known as Slackbot that can keep you on track and make sure you meet deadlines. You can also use public channels to connect with other freelancers. For instance, if you’re a freelance writer looking for guidance on how to publish blog posts, you can consider reaching out to people on the WordPress Slack channel. Public channels are searchable.
