Is the ad copy generator free?

Yes. It is free and runs entirely in your browser. There is no signup, no API key, and no usage limit.

Does my product data leave my device?

No. In this build the copy is produced by a deterministic engine that runs fully client-side, so your product brief never leaves your browser. Nothing is uploaded to a server.

What character limits does it enforce per channel?

Google RSA headlines are 30 characters and descriptions 90; Meta primary text is about 125 characters recommended; TikTok ad captions are 100; Amazon titles are 75 characters (all categories except media, enforced July 2026); eBay titles 80; Etsy titles 140 with 13 tags of 20 characters. A full comparison table is on the page.

Can it write listings for Amazon, Etsy and Shopify?

Yes. It produces marketplace listing copy — title, bullet points, description and tags — for Amazon, eBay, Etsy, Shopify, Walmart and TikTok Shop, each respecting that marketplace's format rules.

Does it check ad policies?

It runs a plain-language compliance pass that flags common issues: over-limit fields, banned characters, all-caps and excessive punctuation, promotional phrases where a marketplace forbids them in titles, and restricted superlative or absolute claims. This is guidance, not legal advice.

Does it make up claims about my product?

No. The deterministic engine only uses the facts in your brief, and it flags any superlative or absolute claim so you can confirm or remove it before publishing.

Does it choose the target audience for me?

Yes. Instead of asking you to type an audience, the tool reads your product and suggests target audiences with age range, gender skew, strong countries, interests, habits and lookalike seed ideas. These are reasoned starting points to test, not measured statistics.

Can it write a video ad script?

Yes. It generates a short-form vertical video ad script with five hook options for the first three seconds and a scene-by-scene breakdown of on-screen text, voiceover lines and shot directions. It writes the script only and does not generate any video or images.
