## What it does
Write 3 openings for each short video with AI, test them as trial reels, and score results after 3 days against your usual views and sign-ups.

## Who it's for
Small businesses and creators posting Reels or Shorts who want to know which openings actually work.

## Tools
- Instagram trial reels, or your usual short video app
- ChatGPT or Claude
- A simple results sheet

## Steps
1. Pick one video. Use the prompt below to write 3 different openings for the first 3 seconds.
2. Edit 3 versions that differ only in the opening.
3. Post them as trial reels where available. Instagram says trial reels are shown to non-followers first and do not appear on your grid unless you share them later.
4. Wait 3 days, then log views, sign-ups or messages for each.
5. Score each: views divided by your usual views for a post. Above 1 is better than usual.
6. After about 30 to 50 tests, write down the patterns that keep winning and use them by default.

## Copy-paste prompt
Adapt bracketed fields to your situation.
```text
Write 3 different openings for the first 3 seconds of this short video. Keep everything after the opening the same.

What the video shows: [DESCRIPTION]
Who it is for: [AUDIENCE]

Make the 3 openings different types: a problem statement, a surprising result, and a direct question. Each under 12 words, on-screen text plus what is said. No claims I have not given you.
```

## Guardrails
- What it touches: Chat input you provide (Instagram trial reels, or your usual short video app; ChatGPT or Claude).
- Needs your OK: Send, pay, publish, and account changes stay with you. Treat agent output as drafts first.
- Safety level: Read-only
- Judging after one day.
- Changing the opening and the music at once.
- Chasing views from people who will never buy.

## Tips
- Change one thing at a time, or you will not know what worked.
- Views are not customers; track sign-ups or messages too.
- Three posts prove nothing; look for patterns over dozens.

## Estimates (labeled, not measured)
- Time saved: About 20 minutes per video.
- Money saved: Not stated in sources.
