AI Facebook Ad Copy Generator

An AI Facebook ad copy generator writes the text fields of an ad for Facebook and Instagram. You enter the product or service, the target audience, what makes it special, and the campaign goal. A language model returns three ad variations, and each one has a headline of up to 40 characters, primary text, a description of up to 30 characters, and a call-to-action button to pick in Ads Manager.

The three variations take different angles: one leads with the problem, one with the benefit, and one with social proof. Testing angles against each other is the usual way to find which one your audience responds to, and having three ready saves an afternoon. The five goals are Sales, Leads, App installs, Traffic and Awareness. The model is told not to invent statistics or testimonials, which matters because a made-up claim in an ad is a policy problem, not only an accuracy one. For search ads with their own length rules, use the Google Ads copy generator instead.

The model runs on the Toolz server. Your form is sent over HTTPS, the server builds the prompt and runs Gemma 3 1B, a small open model from Google, with Ollama, and the ads stream back as they are written. Your product details and unlaunched offers are used to write the reply and then discarded: they are not stored or logged, not used to train any model, and not sent to Meta or any third-party AI company.

Mind the limits. Even when told not to, a 1B model can slip in a number or a promise, so check every claim against what you can prove. It knows nothing about your past campaign results or current ad policy, and it miscounts characters, so check each headline and description against the limit.

It is free with no signup, within about 20 runs per 10 minutes. The alternatives are writing ads yourself, working from a swipe file, hiring a copywriter, or the text suggestions inside Ads Manager. This gives three drafts to test, and keeps none of them.
