Use Case
Facebook UGC Ads: A/B Test Creatives Without the Wait
Facebook ad accounts need a constant stream of fresh creatives. Testing one script with five different faces used to mean hiring five creators. agent-media lets you generate multiple ad variations from the same script by swapping actors, voice tones, and subtitle styles in the CLI. Five A/B creatives for $15, ready in minutes. See pricing.
The Problem: Creative Fatigue Kills Facebook Ads
Facebook and Instagram ad performance degrades as audiences see the same creative repeatedly. This is creative fatigue. The standard fix is to produce more variations. But producing even basic UGC variations is expensive when you are paying real creators.
Most media buyers know that the winning variable in their A/B tests is often the actor, not the script. The same hook delivered by a different face can double or halve your click-through rate. Testing this manually means coordinating with multiple creators, managing timelines, and paying per video.
The result: teams either under-test (2 creatives instead of 10) or overspend on creative production that eats into their ROAS.
The Solution: Same Script, Swap Everything Else
agent-media separates the script from the delivery. Write your winning hook once, then generate variations by changing the actor, voice tone, subtitle style, or background music. Each variation is a single CLI command.
This is the core workflow for Facebook ad testing. You isolate the variable you want to test (actor, tone, style) and hold everything else constant. The CLI makes this trivial because each flag is independent.
You can also use the REST API to build this into your ad management pipeline. Generate creatives programmatically when a campaign launches, or trigger new variations when performance drops. agent-media fits into your existing stack because it is a CLI tool and an API, not another browser app.
Step-by-Step: Generate Facebook Ad Variations
One script, five creatives, five different actors. Total cost: $15.
Write your script
Start with your best-performing hook. Keep it under 25 words for a 10-second video. agent-media validates word count before generating.
Generate variation A (actor: sofia)
$ agent-media ugc "I tried every budgeting app. This one actually stuck. Here is why." \
--actor sofia --style hormozi --tone energetic --duration 10 --sync
Generate variations B through E
Swap the actor flag. Same script, different face. You can also change tone or subtitle style for more test dimensions.
$ agent-media ugc "I tried every budgeting app..." --actor emma --style hormozi --sync
$ agent-media ugc "I tried every budgeting app..." --actor naomi --style bold --sync
$ agent-media ugc "I tried every budgeting app..." --actor marco --tone confident --sync
$ agent-media ugc "I tried every budgeting app..." --actor priya --style tiktok --sync
