Why choose Zoom or Slack?
However, Zoom is slightly more expensive with an entry-level price of $12.50/month/user compared to Slack's $7.25/month/user. Zoom also offers a free trial of 1 month while Slack does not have a free trial, although both platforms offer a free version. Additionally, Slack allows for graphic personalization and has a newsfeed, notes-taking, calendar, and task management features, while Zoom offers whiteboarding, breakout rooms, and online document editing.
