Zetik is a personal AI intelligence agent that monitors the internet around the clock across news, podcasts, blogs, research papers, GitHub, and newsletters. Users define a tracker in one sentence, and Zetik automatically finds relevant sources, filters noise, folds duplicate stories into single cards, and delivers briefings via feed, push notification, newsletter, or RSS. The tool builds a persistent memory of user preferences, refining its output over time based on explicit feedback. Zetik also surfaces connections and opportunities beyond what users explicitly follow, aiming to surface relevant developments from outside a user's usual radar.
