Three layers of agency intelligence

Most agencies lose 40% of their institutional knowledge when a senior hire leaves. BrandBrain makes that knowledge permanent.

๐Ÿ—„๏ธ

Knowledge Layer

Paste any campaign brief, brand guide, or performance note. GPT-4o-mini extracts 3โ€“7 structured knowledge cards with concepts, summaries, and tags.

โš–๏ธ

Judgment Layer

Score new copy 0โ€“100 using David Ogilvy's 15 advertising principles, benchmarked against your own historical winners. Get a rewrite in the same call.

๐Ÿ”ง

Skills Layer

Query your brain in plain English. Get cited answers from your own past campaigns โ€” not generic AI output that sounds like everyone else.

๐Ÿ’ฌ

Citation-backed Q&A

Every answer cites which documents it came from. No hallucinations โ€” just your agency's knowledge, retrieved and explained with precision.

๐Ÿ“Š

Usage Analytics

Track every query, score, and ingest in one place. See usage by day, by client, and by operation so nothing gets lost.

๐Ÿ”—
