What it does
Ad Copy and Creative Variant Agent is built for the part of performance marketing that never ends: writing fresh copy to outrun ad fatigue, without starting from a blank page every time. Give it a product or offer and it returns a full variant set — headline and description pairs for Google Responsive Search Ads, Meta feed ads and LinkedIn Sponsored Content — each sized and truncated to that platform's character limits, tagged with a suggested test group, and built on one of five message axes: price, speed, trust, urgency or social proof. If you supply your past message-axis CTR, the agent ranks those axes against a benchmark and weights the new variants toward what has actually worked, while flagging the fatigued axes worth retiring. That is the difference between generating copy and generating the right copy. Its handling of thin data is what makes the ranking trustworthy. An axis with fewer than thirty past uses is reported as insufficient data and is never called a winner — it is pulled back in the ranking rather than promoted on noise. And if you supply no past performance at all, the agent runs no CTR analysis and invents no numbers: variants spread evenly across all axes and the warnings say exactly that. Every variant also goes through a pre-publish policy scan that flags superlative, guarantee and medical-claim phrasing — the wording that most often trips an ad review and costs you a day. `scan_policy` returns only the flagged ones, which is the list you actually want before submitting. `check_platform_limits` reports the fit per variant, and each variant carries its exact character count against the platform limit plus a note when a shorter phrasing was used to fit. Every character of copy and every number is produced by the deterministic core. The model narrates which axes to scale or retire and nothing else. No connectors and no credentials — no live ad-platform access, and the agent never publishes. Built for performance marketers.
