About markencheck.ai
AI-powered trademark research — built by a founder who experienced the problem firsthand.
As a founder, I experienced firsthand how hard it is to get an early, clear overview of potential trademark conflicts. Between manual research, complex register data, and hard-to-interpret results, a quick, understandable first step was missing. That's why I built markencheck.ai.

Trademark research shouldn't be a black box
Trademark research is the most important step before filing — but for most founders, it's a black box. Expensive attorneys, incomprehensible reports, incomplete register searches: we believe every founder deserves access to fast, understandable preliminary research. Markencheck.ai makes trademark research accessible — without jargon, without waiting.
Technology & Expertise
AI scoring based on real decisions
Our ML model was trained on over 10,000 EUIPO opposition decisions — for reproducible, transparent results.
Phonetic & visual analysis
Multiple algorithms analyze sound and letter patterns simultaneously — finding matches that a text search misses.
Deterministic scoring
No generative AI in the scoring. The same input always produces the same result — transparent and traceable.
Transparency matters to us
markencheck.ai is a technical research tool — not a substitute for legal advice. For a legally sound trademark clearance, we recommend a specialized trademark attorney. What we offer: a fast, understandable first step — before you invest in attorneys and branding.
