What it does

Generates the carousel, puts a human in the loop for a fast yes/no, then publishes. It bridges the gap between automated rendering and the judgment call a brand owner still wants to make before anything goes live.

When to use it

Use it when you want speed but not full automation: the machine does the rendering work, a person approves in Slack, and publishing happens immediately on approval. Good for small teams where one person owns the final say.

How it works

  1. 1Trigger fires from a webhook when a brief is submitted for rendering.
  2. 2An image step generates the carousel slides from the brief copy and art direction.
  3. 3The rendered preview is posted to a Slack approval channel with approve and reject actions.
  4. 4A logic gate waits for the reaction and branches: reject ends the run, approve continues.
  5. 5The output step publishes the approved carousel to the connected social platforms.
