The thing you sell is invisible, so ads default to a screenshot and a caption. A feature brief is enough to start.
Lead with the outcome, mention the feature second, and end with a CTA that names the action. The release no longer waits on a design slot.
Three rows, one claim per row, stated as a fact about you — never an insult about them.
A 30- or 60-second sequence drafted from the feature description, then edited like a document — faster than briefing a video team.
