Way 1: without AI (the manual way)
Honest cost: half a day per brief.
- Chase the requester for the missing pieces: goal, audience, budget, dates.
- Assemble the brief in your template from chat threads and voice notes.
- 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.More on this prompt: the free ai campaign brief generator prompt 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 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.
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.

| Way 1: manual | Way 2: DIY AI | Way 3: $19 agent | |

| Every run after | Same hours, every time | Re-paste the rules, sheet and context each run | One short ask, or a standing cycle |
| 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.
