# How to write a campaign brief as a marketer

There are three honest ways to write a campaign brief: manually (about half a day per brief), with DIY AI prompting, or with a $19 ready-made agent. This guide compares all three with real pros and cons.

It normalizes the request into a complete campaign brief in a Google Doc, evidence-linked, with the open questions called out for a human to answer. Here are the three honest ways to get it done, with real trade-offs.

[Compare the 3 ways](#compare)[Skip to the ready-made agent](#way3) [Home](/) › [How-to guides](/how-to/) › Campaign Briefs

## Way 1: without AI (the manual way)

**Honest cost: half a day per brief.**

1.  Chase the requester for the missing pieces: goal, audience, budget, dates.
2.  Assemble the brief in your template from chat threads and voice notes.
3.  Review for gaps, send for comments, merge the feedback.

A launch request arrives as a voice note and three chat messages. Turning it into a real brief - objective, audience, message, channel, assets, open questions - eats the afternoon the campaign was supposed to save.

### Pros of doing it manually

  - Free except your time - no tools, no accounts.
  - You learn the job deeply and control every detail.
  - No data leaves your hands.

### Cons of doing it manually

  - half a day per brief - every single time the job runs.
  - Quality depends on your energy that day.
  - More volume just means more hours; it does not scale.

## Way 2: with AI, but without AI Agent Skills (DIY prompting)

A chat assistant genuinely helps here. The catch is that you become the workflow designer. What you have to figure out yourself:

  - You must paste your brief template and house style every time.
  - You must explicitly tell it to list unknowns as questions, or it fills gaps with plausible invention.
  - You must re-explain your channels and naming conventions each run.

Here is a starter prompt that works - copy it and bring the inputs listed:

    Turn this launch request into a campaign brief: [paste request]. Fill: objective, audience, message, channel, assets. List everything missing as OPEN QUESTIONS at the end - do not guess. Keep it to one page.

### Pros of DIY prompting

  - Free, or nearly - any chat assistant works.
  - A first draft in minutes instead of hours.
  - Fully flexible: tweak the prompt for any edge case.

### Cons of DIY prompting

  - You become the workflow designer: prompts, test data and output rules are yours to write, test and maintain.
  - Output drifts between sessions unless you re-paste the rules every run.
  - Nothing is saved for you - sheets, structure and context are rebuilt each time.

## Way 3: with AI Agent Skills ($19, one-time)

The [Campaign Brief Agent](/marketing/campaign-brief-agent/) is this job already designed: fixed evidence rules, output contract, test fixtures and stop points. You ask once:

> Hello, turn this launch request into a campaign brief

And a finished, review-ready artifact lands in your own Drive:

| Objective                 | Audience                             | Message                    | Channel                   | Asset        | Open question           |
| ------------------------- | ------------------------------------ | -------------------------- | ------------------------- | ------------ | ----------------------- |
| Drive demo bookings       | Ops leads at 50-500 person companies | Follow-ups run themselves  | LinkedIn + email sequence | One-pager v3 | Which case study leads? |
| Re-engage trial drop-offs | Trials inactive 7+ days              | Pick up where you left off | Email win-back            | None         | Approved by Sam Sep 11  |

*Sample data shown. Your workspace fills with your real work.*

Setup takes about 10 minutes: buy, hand the three files to the assistant you already use (Instinct, ChatGPT, Claude, Gemini or any other assistant that reads files), approve the fictional-data test. Then it runs on a standing cycle or a one-line ask, and stops at every human gate. [Full method](/how-it-works/).

### Pros of the ready-made agent

  - About 10 minutes to a tested setup, not an afternoon of prompt tuning.
  - The same output shape every run - evidence rules and stop points are already designed.
  - Runs on a standing cycle or a one-line ask; files land in your own Drive.

### Cons of the ready-made agent

  - Costs $19 once, where DIY prompting is free.
  - The output format is opinionated - you adapt the template rather than rebuild it.
  - It still stops and waits for your approval at decision points; it is not zero-touch.

| Consistency          | Depends on the day     | Drifts between sessions                        | Same output shape every run        |
| Cost                 | Your hours             | Free, plus your time                           | $19 once, files kept forever       |

The manual way teaches you the job. DIY prompting is fine for a one-off. The agent wins when the job repeats every week.
