How many people scroll past your ad before one stops? Do you know whether it was the first line that lost them, or the offer? And how do you write a fourth version when the first three did nothing?
Ad copy is a volume game before it is a craft. The Facebook Ad Copy Generator gives you variations quickly, each built on a named persuasion framework instead of a guess.
Short answer: The Facebook Ad Copy Generator writes ad body copy built on a named persuasion framework, from AIDA to PAS or Social Proof, at the objective, tone and length you choose. Free to use on EizTools with no account.
What is Facebook Ad Copy Generator?
It is a copywriting workspace aimed at paid social. You describe the product, the audience and the offer, then choose what the ad is meant to achieve. The output is body copy you can paste into Ads Manager and test.
The Copy Framework setting is what separates it from a general writing tool. AIDA opens with attention and closes with action. PAS leads with the problem. FAB argues from features to benefits. Same product, genuinely different ads.
How Does Facebook Ad Copy Generator Work?
- Describe the product, the audience and the offer in the prompt box.
- Choose which AI model writes the ad.
- Open the advanced options and set Ad Objective, Copy Framework, Tone and Ad Length.
- Generate. The copy appears in the output card with a word count and reading time.
- Copy it, download it as TXT, Word or HTML, or reopen an earlier version from the activity history.
| Option | What it changes | Where to start |
|---|---|---|
| Ad Objective | Eight objectives, from Conversions and Leads to Awareness and Retargeting | Match it to the campaign objective you already set in Ads Manager |
| Copy Framework | AIDA, PAS, FAB, Story, Direct and three more argument shapes | PAS for a product that solves an obvious frustration |
| Ad Length | Short, Normal or Detailed body copy | Short for cold traffic, Detailed for retargeting |
| Persuasiveness | Slider from 1 to 100 controlling how hard the copy pushes | Around 60, since a maxed out setting reads like a late night infomercial |
Tone covers Persuasive, Urgent, Friendly, Bold, Professional and more. Four toggles add a call to action, urgency, emojis or social proof. Custom Instructions is where the details live: the price point, the guarantee, a phrase your compliance team will not allow.
Pro tip Generate the same brief three times, changing only Copy Framework. You get three ads that argue differently rather than three rewordings of one idea, which is what makes a test worth running.
Objective, Framework And Tone Explained
These three settings do almost all the work, and they interact.
- Objective sets what the copy asks for. An Awareness ad that ends in Buy Now is asking too early.
- Framework sets the shape of the argument. Story ads run longer, Direct ads run short.
- Tone sets the voice. Urgent works on a deadline offer and undermines a considered purchase.
A practical example: a small studio selling a beginner pottery course set Ad Objective to Leads, Copy Framework to PAS, Tone to Friendly and turned on Add Social Proof. The result opened on the frustration of never finishing a creative hobby, then offered the free first class.
Writing Variants Worth Testing
What it does well
- Produces several genuinely different angles from one brief.
- Keeps the copy on the framework you chose instead of drifting.
- Handles the short first line that decides whether anyone reads on.
- Free, with no account, so testing ideas costs nothing.
What it cannot do
- It has no access to your ad account, so it cannot see what performed.
- Claims about results or refunds have to be checked by you against platform policy.
- It writes copy, not creative. The image or video is still your job.
The whole EizTools suite is open without payment or registration, and switching AI families between runs matters here because different models pitch the same product in noticeably different ways. If the same campaign is running on search as well, the Google Ads Copy Generator handles that side.
Frequently Asked Questions
Which framework should I pick if I am unsure?
Start with PAS. Naming a real frustration and then answering it is the safest structure for cold audiences, and it gives you a clear baseline to test other frameworks against.
Does it write headlines as well as body copy?
The output is built around the ad body, and short opening lines usually come with it. Ask for headline options in Custom Instructions and they are included in the same result.
Will the copy pass Facebook's ad rules?
Treat every draft as unchecked. The Facebook Ad Copy Generator does not review policy, so claims about income, health or personal attributes need your own check before the ad goes live.
How many versions should I test?
Three is usually enough to learn something. Change one setting between them, keep the offer identical, and you will know which angle earned the result rather than guessing.
Good ad copy is mostly a numbers problem: you need enough real options to find the one that works. Generating those by hand is slow, which is why most accounts test two ads and stop. The Facebook Ad Copy Generator makes the fourth and fifth version cheap, and those are often the ones that surprise you.
