Real-time Sentiment Analysis Dashboard for Streaming Platforms

Overview
A comprehensive B2B SaaS platform that transforms how content creators understand and engage with their audiences through real-time sentiment analysis. Built to address the gap in deep audience insights within the $2.5B streaming analytics market, this solution processes millions of chat messages to provide actionable engagement metrics.
The platform emerged from recognizing that successful streamers needed more than viewer counts—they needed to understand the emotional pulse of their community to create content that truly resonates.
