Message body
How it works
Does CyDuck store my message?
No. Your message is analyzed in real time and immediately discarded. Nothing is logged or stored at any point.
How does the detection work?
CyDuck uses two layers. First, fast pattern analysis checks for known spam signals — typosquatted domains, urgency language, URL shorteners, delivery scam patterns, and credential requests. For borderline cases, an AI model performs a deeper contextual analysis. Obvious spam is caught immediately without any AI call.
Can this guarantee a message is safe?
No tool can guarantee 100% accuracy. CyDuck provides a probability score and explains its reasoning. Spammers constantly evolve their tactics. When in doubt, navigate directly to a company's website rather than clicking any link.
What is "pattern analysis" vs "AI analysis"?
Pattern analysis uses rule-based checks that run instantly and are highly reliable for obvious spam. AI analysis uses a language model to understand context, detect subtle manipulation, and catch patterns that rules might miss. Both are shown in the result so you know which method was used.
