Start using AI sentiment analysis tools

In this run down of the best AI sentiment analysis tools, we’ll introduce you to the most powerful solutions for monitoring customer sentiment across your social media channels. First, though, let’s go over what a sentiment analysis tool is and what sentiment analysis can do for you.

What Is A Sentiment Analysis Tool?

A sentiment analysis tool is software that analyzes text data to help you quickly understand how customers feel about your brand, product or service. Sentiment analysis tools can automatically detect the emotion, tone, and urgency in online conversations, assigning them a positive, negative, or neutral tag.

You can opt to use ready-made sentiment analysis tools that come with APIs and integrations, or build your own using open-source software.

Benefits of Sentiment Analysis Tools

Instead of manually labeling each Facebook comment or Tweet as positive or negative, you can harness the power of sentiment analysis to sort social media data automatically.

By connecting sentiment analysis tools to your customer service software, you can listen to your customers in real time, prioritize negative comments and, in doing so, prevent customer churn.

And you can transform all your sentiment data into insights that reveal trends and patterns over time. With sentiment analysis tools, turn your unstructured data into structured data so you can easily spot problem areas and make data-based decisoins that will drive your business forward.

To automatically detect positive and negative sentiment within your data, get started with some of the following online sentiment analysis tools.
