A brand brief tells the AI what matters in your footage: what you sell, who it's for, what to watch for and what to ignore. It's built from your website and category, and it's why a cookware brand's library tags "food release test" instead of "product in use".
A brand brief is the short document the AI reads before it watches your footage. What you sell. Who buys it. The moments that matter in your category. The things that are incidental.
Without it, analysis is generic: "person holds product". With it, analysis is specific: "egg sliding off the pan", "texture on fingertips", "noise test next to the unit".
In BuildYourAds the brief is written from your website and the category you pick when you create a workspace. It sets the label taxonomy (cookware gets 14 cooking actions, skincare gets 12 application moments) and tells the analyzer what to pay attention to. You can rewrite it from Settings at any time, and the analyzer suggests new labels it keeps seeing in your actual footage.
Let's say a cookware brand's brief says to watch for food release, surface close-ups and cleaning, and to treat the creator's kitchen decor as incidental. A clip of someone wiping a pan gets tagged "Cleaning or wiping the pan", not "kitchen".
No. It's generated from your website and category, then you can edit it. Most brands never touch it; the ones with unusual products add two or three lines.
Pick "Something else". You get the shared taxonomy (hooks, demos, testimonials, b-roll basics) and the analyzer proposes category-specific labels from the first clips you upload.
