GAC member David Nowotnik has built a number of applications that may be helpful to genealogists. All of these applications utilized artificial intelligence to assist in the coding; so-called 'Vibe Coding'. These applications are available free-of-charge on another website. Use the links below to access these offsite applications. (Updated Dec 2, 2025).
