The Best 12 Sentiment Analysis Tools in 2021

Written by Clint Fontanella @ClontFont


Have you ever received a text from a family member and couldn’t tell if they were joking or not? Unless we directly tell the person how we feel, emotions and tone don’t carry well over text, which often makes it difficult to determine the intent of a message. We can use punctuation to help, but there’s no universal way to communicate things like sarcasm or irony through text.

In 1580, English printer, Henry Denham, tried to solve this problem by coming up with this mark to symbolize sarcasm: ⸮

Spoiler alert, it never quite caught on and when technology like text messages, live chat, and social media came me about, people still had no definitive way of identifying the sentiment behind a text message. This became a real problem for businesses as they realized how difficult it was to determine if customer feedback was positive or negative. It’s hard for a customer to describe a problem when they only can use 280 characters, and without proper context, customer service teams don’t have the information they need to appropriately respond to the issue.

As text-based communication like social media and live chat become more popular in customer service, businesses need a way to accurately and efficiently filter their customers’ feedback. This is where a sentiment analysis tool comes in handy to interpret a text and explain the intent or tone of a customer’s message.

In this post, we’ll explain what a sentiment analysis tool is and provide a list of the best options available for your team this year.

What Is a Sentiment Analysis Tool?

A sentiment analysis tool is software that analyzes text conversations and evaluates the tone, intent, and emotion behind each message. By digging deeper into these elements, the tool uncovers more context from your conversations and helps your customer service team accurately analyze feedback. This is particularly useful for brands that actively engage with their customers on social media, live chat, and email where it can be difficult to determine the sentiment behind a message.

Brand Sentiment Analysis

Sentiment analysis helps brands learn more about customer perception using qualitative feedback. By leveraging an automated system to analyze text-based conversations, businesses can discover how customers genuinely feel about their products, services, marketing campaigns, and more.

Benefits of Adopting a Sentiment Analysis Tool

If your company provides an omni-channel experience, a sentiment analysis tool can save your team valuable time organizing and reporting customer feedback.

Rather than going through each tweet and comment one-by-one, a sentiment analysis tool processes your feedback and automatically interprets whether it’s positive, negative, or neutral. Then, it compounds your data and displays it in charts or graphs that clearly outline trends in your customer feedback. This not only gives your team accurate information to work with, but frees up time for your employees to work on other tasks in their day-to-day workflow.

Now that you know what a sentiment analysis tool is and how it can benefit your business, let’s take a look at some of the best tools available for 2021.

Critical Mention is different than the other options on this list because it analyzes news and other publications that reference your business. This way, you can see the sentiment behind stories that are rapidly surfacing to the public.

If your business gets positively mentioned on a live broadcast, quickly access the video segment and share it on your social media channels. This can help you create effective online content that capitalizes on timely marketing opportunities.

Additionally, Brandwatch’s software provides interesting insights into each image it finds. This includes metrics like mention volume, aggregate followers, and latest activity.

Social Mention is a free social media analysis tool that provides users with one of the best bangs for their buck. First, users don’t have to create an account or download software. Instead, you just need to navigate to their site and search for your keyword like you would with any search engine. Upon entering your search, Social Mention pulls data about your keyword from every social media site and compiles it into a comprehensive summary.

This summary isn’t primitive, either. It can tell you useful things like the ratio of people speaking positively about your keyword versus those who are speaking of it negatively. It can also tell you what percentage of people are likely to continue mentioning your keyword and how popular your brand is on social media. While you can’t really analyze individual pieces of data, Social Mention is a great option for people looking to get a brief synopsis of their social media reputation.

Working with Sentiment Analyzer is a breeze. Simply navigate to their site, copy the text you want to analyze, and paste the text into the box. Select “Analyze!” and the website will evaluate your text and give you a “sentiment score.”

It then compounds and compares its findings to produce an overall score. This makes it a great tool for companies looking to quickly decipher the intent behind a confusing response from a customer.
