## What it does
Use AI to draft Facebook ad angles, copy and a weekly test plan, then launch and control spend yourself in Ads Manager with a spending limit.

## Who it's for
Small businesses who want Facebook ads to work but do not want a bot spending money on its own.

## Tools
- ChatGPT, Claude or Grok Bot
- Meta Ads Manager
- 10 real customer reviews or messages

## Steps
1. Set an account spending limit in Ads Manager first. Meta says you set your ad account spending limit, and ads pause when it is reached.
2. Paste 10 real reviews or customer messages into the prompt below to get 3 angles in your customers' words.
3. Pick 2 angles and launch them yourself as a small test.
4. After 7 days, paste the Ads Manager results into the same chat and ask what to keep, cut or change.
5. Make changes yourself. Do not give an agent your ad account login.
6. Keep a one-line log per week: angle, spend, result.

## Copy-paste prompt

Help me plan a small Facebook ad test. Use only what I paste.

What I sell and to whom: [DESCRIPTION]
Real customer reviews or messages: [PASTE 10]
Weekly budget I set: [AMOUNT]

1. 3 ad angles, each built on words customers actually used (quote them)
2. For each: primary text under 125 characters, a headline under 40, and an image idea
3. A 7-day test plan for 2 angles
No claims about results, prices or guarantees I did not give you.
```

## Guardrails
- What it touches: Connected mail, calendar, sheets, or chat. Scoped to this job (ChatGPT, Claude or Grok Bot; Meta Ads Manager).
- Needs your OK: Send, pay, publish, and account changes stay with you. Treat agent output as drafts first.
- Safety level: Drafts for you
- Giving a bot the ad account login.
- No spending limit set before launch.
- Copy that promises results you cannot back up.

## Tips
- Customers' own words make the strongest angles.
- Test 2 angles at a time, not 10.
- Results after 2 days are noise; wait the full week.

## Estimates (labeled, not measured)
- Time saved: About 1 hour per test.
- Money saved: Not stated in sources.
