Architecture Overview

Inspiration

In a digital age where our personal lives and the digital space is increasingly intertwined, our Personally Identifiable Information (PII) becomes ever more valuable for malicious actors(e.g. scammers). The implications of a PII leak today has never been more grave than ever before. Therefore, we introduce Beep, an innovative real-time chat application built for the TikTok Hackathon featuring advanced voice messaging capabilities with intelligent PII (Personally Identifiable Information) detection and automatic redaction. This platform ensures user privacy while maintaining seamless communication through cutting-edge AI technologies. We hope to inspire a new generation of real-time chat applications that are centered on protecting their user's PII.
