Facebook Ad Copy Generator
Generate Facebook ad copy with AI — 3 ad variations with headline, primary text and description, shown as ad mockups with character limits.
About the Facebook Ad Copy Generator
This free AI Facebook ad copy generator writes three complete ad variations from a description of your product, your target audience and your campaign goal. Each variation includes the three text fields a Facebook ad needs: primary text (the message above the creative), the headline, and the link description.
Results are rendered as ad-style mockup cards so you can judge them the way users will see them, with live character indicators against Meta's recommended limits — about 40 characters for headlines and 30 for descriptions before truncation on most placements. Primary text is kept punchy, since only the first ~125 characters show before "See more".
Testing multiple copy angles is the core of Facebook ads optimisation, and three distinct variations give you an instant A/B/C test. Copy any variation with one click, or regenerate for three new angles. Free, no signup.

Frequently Asked Questions
What are the character limits for Facebook ads?
Meta recommends about 125 characters of primary text before truncation, roughly 40 characters for headlines and 30 for link descriptions (exact display varies by placement). Longer text is allowed but gets cut with "See more". The tool's counters show green when a field fits the recommendation.
What is primary text vs headline vs description?
Primary text is the message that appears above the image or video — the main copy. The headline is the bold line under the creative next to the call-to-action button, and the description is the smaller grey text below the headline (shown only on some placements).
Why generate three ad variations?
Because ad performance is hard to predict — the angle you like least often wins. Running 2-3 copy variations against the same audience lets Meta's delivery system find the winner quickly, usually within a few days at modest budgets.
Will this copy pass Facebook's ad review?
The generator writes conventional marketing copy, but you're responsible for compliance: avoid prohibited claims (health cures, guaranteed income), excessive capitalisation, and personal attributes ("Are you diabetic?"). Check Meta's advertising policies for your industry, especially finance, health and employment.
Can I use the copy for Instagram ads too?
Yes — Meta runs Instagram ads through the same Ads Manager with the same text fields, so the primary text and headline work across both. Instagram placements show even less text before truncation, so favour the shorter variations.
