Why LexAi?

After years of direct-response copywriting and translating high-stakes campaigns as a bilingual copywriter at Amazon, I realised something was deeply broken in global marketing: translation and performance lived in separate universes. Millions were poured into high-quality creative and localisation, yet content often fell flat once it reached international audiences. The issue wasn’t the language – it was the absence of data-driven optimization.

LexAI is the first AI-powered platform that turns translation from a cost-center into a performance engine. By analysing historical campaign data, generating context-aware prompts and integrating seamlessly via API, LexAI lets you A/B test, iterate and scale high-impact copy in every market. In a world where attention is currency, LexAI helps you speak the language of results.
