The prompt · creative brief

Write a creative brief for our next video ad about greens powder. Base it on the longest-running video ads of AG1 and Grüns, cite each ad you use, and say which angle we should test first.

Change the words in the fields and the prompt follows; the steps stay the same. Send it as it is, or ask in your own words.

The evidence a brief rests on: hooks, formats, messages and offers counted over 8 video ads saved in a collection on greens powders (Huel, Grüns, AG1), from a snapshot of the shared library taken on 23 September 2026. The brief itself is your AI's writing.

Good to know before you run it

  • The brief is your AI's writing on Adspy's evidence: check the cited ads before you brief a team.
  • Longevity is a signal of what brands keep running, not proof of results.
