What is AI Sentiment Analysis Tool?
Cobain AI's AI Sentiment Analysis Tool reads text and tells you the emotional tone behind it — positive, negative, or neutral — along with a short explanation of why. Paste customer reviews, social comments, survey responses, or support messages, and the AI helps you spot how people really feel at a glance. It's made for marketers, support teams, and small business owners who want to understand feedback quickly without manually reading through hundreds of messages.
