The problem
Bad briefs are one of the most expensive problems in a marketing agency. When the creative or strategy team starts work from a brief that is incomplete, ambiguous, or misaligned with what the client actually wants, the result is rework. Rework is unpaid time. It erodes margins, demoralises creatives, and damages client relationships when the first round of work misses the mark.
The problem usually starts in the client conversation. Account managers are skilled at building relationships and managing expectations, but capturing structured information while simultaneously running a meeting is difficult. Notes taken during a call are often fragmentary. Key details get missed. The nuance of what the client really means — the emphasis they put on a particular phrase, the hesitation in their voice when they mentioned budget, the specific problem they kept returning to — does not survive the translation from conversation to written brief.
The briefs that emerge from these conversations are often more of a summary of the meeting than a proper brief. They might tell the creative team what the client said, but not what the client needs. They might describe the deliverables requested without capturing the strategic context that would help the team make good decisions. Fixing this manually requires either more time in the meeting taking notes, or a follow-up call to fill in the gaps — both of which create friction in an already busy account management workflow. AI offers a better path: capture the conversation fully, then use structured prompting to extract everything a creative brief needs.
The system
Step 1: Record and transcribe the briefing call (Otter.ai)
Enable Otter.ai on every client briefing call. Otter integrates directly with Zoom and Google Meet and will automatically join and transcribe. After the call, you receive a full transcript within minutes.
Brief your clients that you record calls for accuracy — most professionals are comfortable with this and it signals that you are serious about getting the detail right. For clients who prefer not to be recorded, use Otter.ai as a live notes tool during the call instead.
Review the transcript immediately after the call while the conversation is fresh. Highlight or mark any sections that felt particularly important or unclear.
Step 2: Extract the raw brief information (Claude)
Paste the call transcript into Claude with an extraction prompt:
"The following is a transcript of a briefing call between a marketing agency and a client. Extract the following information and present it clearly: 1) The business problem or opportunity the client is trying to address. 2) The campaign or project objective (what does success look like to them?). 3) The target audience as described by the client. 4) Key messages or claims the client wants to make. 5) Any executional requirements or constraints mentioned (budget, timeline, channels, mandatory inclusions). 6) Any preferences or strong opinions the client expressed. 7) Any open questions or areas where the brief was unclear or incomplete. Here is the transcript: [paste]."
This extraction takes 30 seconds and surfaces everything that was actually said, organised in a way that maps onto a proper brief structure.
Step 3: Write the creative brief (Claude)
With the extracted information, write the formal brief:
"Using the following extracted briefing information, write a structured creative brief for a marketing agency. The brief should include these sections: Background (who is the client and what is their situation), Brief (what are we being asked to do), Objective (what does success look like, with any measurable targets mentioned), Audience (who are we talking to and what do we know about them), Key Message (the single most important thing we want the audience to think, feel, or do), Tone of Voice (how should this feel), Deliverables (what are we producing), Timeline (key dates and milestones), Budget Guidance (if mentioned), and Open Questions (things we need to confirm before work starts). Write in clear, direct language. This brief is for an internal creative team, not for the client. UK English."
The result is a professional, structured brief that gives your team a solid foundation to work from.
Step 4: Fill the gaps before sharing (Notion AI)
Before you share the brief with the creative team, use the Open Questions section to identify anything critical that is missing. If budget was not mentioned, that is a blocker. If the target audience is vague, that needs resolution. If there is a contradiction in what the client said at different points in the call, surface it.
Use Notion AI to draft the follow-up email to the client asking for clarification:
"Write a brief, professional email to a client following a briefing call. We need to confirm the following information before work starts: [list open questions from the brief]. Keep the email warm, efficient, and not longer than 150 words. UK English."
Step 5: Version and store (Notion)
Save every brief in a Notion database with fields for: client name, project name, brief date, status (draft / approved / in progress / delivered), and a link to the call recording. This creates a searchable archive that is invaluable for onboarding new team members, resolving scope disputes, and improving briefing quality over time.
Tag briefs by client and project type so patterns become visible. If a particular client is consistently unclear about audience, you can address that in future briefing call agendas.
The results
Before this workflow, briefing documents were typically produced from fragmented notes within a few hours of the call. They were incomplete 40 to 60% of the time, requiring at least one round of clarification before creative work could begin.
With this system, brief quality improves significantly: the Open Questions section catches missing information before work starts rather than after. Time to produce the brief drops from 60 to 90 minutes to 20 to 30 minutes. Rework from misaligned first rounds decreases by an estimated 30 to 40%. Over the course of a year, for an agency doing 100 plus client projects, that represents dozens of hours recovered and a material improvement in both margin and client satisfaction.
