FEELFLOWAI

Full-stack web application that uses advanced artificial intelligence to analyze sentiment and detect 12 specific types of toxicity in YouTube comments

The Problem

Content creators and brands on YouTube face the challenge of manually moderating thousands of comments, without effective tools to automatically detect toxic content, hate speech, threats, and other types of problematic behavior. This manual moderation consumes significant resources and is prone to human error.

The Solution

Development of an AI system that combines sentiment analysis with multi-class toxicity detection using a custom hybrid BiLSTM model. The system processes YouTube comments in real-time, identifies 12 specific types of toxicity, and provides calibrated risk metrics through an interactive dashboard.

Impact

Identifies problematic content with 95.8% accuracy, facilitating automatic moderation and data-driven community management strategies. Detects potential sarcasm and provides risk metrics per video, optimizing resources through calibrated predictions.
