Brief GPT
A structured brief in 90 seconds, trained on real Zerologic work.
About
Brief GPT started as a prompt. A prompt we refined over about six months of actual client engagements until it was producing briefs that were genuinely useful — structured, specific, and grounded in the category logic of the particular client.
We then trained it on 50+ real briefs from Zerologic projects. Not the sanitised versions — the actual working documents, with their messy stakeholder notes and contradictory objectives and underlined questions.
The result is a system that understands what makes a brief good in context, not just in theory. Give it your category, your goal, and your budget, and it generates a brief template that you actually want to fill in.
