The Copy Agent: Multi-Model Marketing Copy in 29 Languages

Marketing is a numbers game played by tired people. The Copy Agent plays it for you: one product brief becomes launch emails, landing copy and ad variants drafted across four models, scored against your brand voice profile, localized to 29 languages, and delivered as a reviewable package — not a wall of tabs.

Why four models, not one

Ask one model for ten headlines and you get ten variations of its favorite structure. Ask GPT-5, Claude, Gemini and Grok for three each and you get genuinely different angles — the cautious one, the funny one, the contrarian one. The agent scores every variant against a brand voice profile you define once (paste three examples of copy you love; it extracts the pattern), and presents the shortlist with reasoning.

Angle A — benefit-ledscore 8.4

Angle B — story framescore 9.1

Angle C — data hookscore 7.8

Angle D — contrarianscore 8.9

Four angles, scored, localized

Localization ≠ translation: the agent adapts idiom, formality (German Sie vs du is a brand decision, not a grammar one) and legal disclaimers per market — then a native-speaker review pass is one click for any line you flag.
