How is this different from Slack Block Kit Builder?
Slack's Block Kit Builder helps developers design message layouts and export JSON. This free broadcast planner helps teams decide what to communicate, which audience needs it, what action to request, and how to follow up. It generates editable copy rather than executable Block Kit components.
