Editor's takeSlack has grown from chat app into a work hub, with native AI now summarizing threads and searching across connected tools. Internal data shows meaningful time savings, and its 2,600-plus app directory beats most collaboration rivals. Teams wanting the full AI feature set should budget for Business+, since the standalone AI add-on was retired.
Does Slack have a free plan?
