Frequently Asked Questions

How much does it cost to generate ad copy?

A typical generation of 3 ad variations costs $0.01–$0.03 depending on the model. Compare that to freelance copywriters ($50–$200 per ad) or agencies ($100–$500+). You bring your own API key from OpenAI or Google and pay only for the tokens used.

What platforms are supported?

Five platforms: Facebook Ads (primary text + headline + CTA), Google Ads (30-character headlines + 90-character descriptions), Instagram Captions (with hashtags), LinkedIn Posts (professional tone), and Twitter/X Posts (under 280 characters).

Does this handle Google Ads character limits?

Yes. When you select Google Ad, the generator produces headlines within Google's 30-character limit and descriptions within the 90-character limit. Character counts are displayed on each variation so you can verify compliance before pasting into Google Ads.

Is my data private?

Yes. Everything runs in your browser. Your product details go directly from your browser to the OpenAI or Google API — they never touch our servers. There is no backend. Your API key is stored locally in your browser and never transmitted to us.

Can I use this for client work?

Absolutely. The generated ad copy is yours to use however you like — for your own business, clients, or agency work. There are no usage restrictions. Many marketers use this to generate first drafts they then refine for their specific campaigns.
