Luxcerta與日月爭輝

Contending with the sun and moon

Luxcerta — lux (light) + certa (certain). We build measurement tools for the AI era: showing brands what AI actually says about them, and letting data speak for decisions. Every number can be verified by you. What we didn't measure, we don't claim.

Two product lines

Luxcerta GEO

What is AI telling people about your brand? We ask AI platforms real users' questions, repeatedly, and count who gets recommended, who gets cited, and who gets misrepresented — brand-visibility measurement for the generative-engine era.

E-commerce AI analytics

A purchase-pattern analysis SaaS: repurchase rhythms and customer profiles from your order data, turned into actionable insight by AI. (Moving to shop.luxcerta.com soon.)

Our principle

What we didn't measure, we don't claim. Every number ships with its method and limits; thin samples are labeled thin; mistakes are corrected in public. For a one-person studio, trust is the one thing we cannot afford to lose.
