01 Brand24

Let’s start our list with Brand24!

Brand24 is an AI-powered media monitoring tool that detects, tracks, and analyzes mentions published in multiple sources on the web.

The tool offers intuitive and advanced sentiment analysis boosted by the power of artificial intelligence.

I mentioned that Brand24 monitors many online sources. Which exactly?

Well:

• Social media platforms, including Facebook, Instagram, TikTok, X (Twitter), YouTube, LinkedIn, Reddit, Telegram and Twitch;
• News sites, blogs, video platforms, podcasts, and other websites;
• Review platforms and newsletters.

Pretty much, don’t you think?

Moreover, Brand24 collects all mentions in real time and offers excellent media monitoring analytics. Taken together, these elements make Brand24 one of the best sentiment analysis tools available.

Ok, enough theory! I’ll show you Brand24’s capabilities in practice.

Since I promised you in the title that you’ll “shine bright like a diamond”, let’s do a sentiment analysis for the lady singing these words – Rihanna!

First, we’ll take a look at the overall sentiment toward RiRi.

The Brand24’s Mentions tab allows you to see the Sentiment chart. The green line indicates the positive sentiment, while the red is the negative sentiment. The neutrals are excluded from the chart.

Obviously, in the measured period (30 days), favorable online mentions appear much more frequently.

If you visit the Analysis tab, you can get more details.

It turns out that 81.7% of mentions were positive and only 18.3% – negative (excluding neutrals). Great ratio, RiRi!

Most sentiment analysis tools stop over here. They can detect only negative, positive, and neutral sentiments.

But Brand24 is different.

Thanks to advanced sentiment analysis based on natural language processing (NLP), Brand24 can detect more specific emotions.

Precisely, the tool’s AI detects six feelings: admiration, anger, disgust, fear, joy, and sadness. You can check them in the AI Emotion Analysis tab.

The most popular emotional tone expressed when people talk about Rihanna online is admiration. No surprise at all!

Next, you can explore the AI Topic Analysis to discover the most popular themes people discuss when talking about your brand.

Each topic includes a short description of a cluster, the volume of mentions on that matter, their reach, share of voice, and a sentiment share.

You can click “More stats” for a more detailed overview of a particular topic.

As you can see, in June 2024, Rihanna’s fans were interested in her personal life, music, and the artist’s new Fenty Hair product line.

Speaking about AI features, I’d like to briefly show you my favorite Brand24 feature – the AI Anomaly Detector.

It helps you understand what caused the sudden sentiment changes.

AI Anomaly Detector is your personal 24/7 guard. In short, it constantly watches your project to discover any anomaly that could impact your reputation and sentiment.

For example, suppose you suddenly receive significantly more brand mentions than usual.

In that case, the Anomaly Detector will notice it, search the web for the most likely reason, and present its findings in one or two key sentences.

To see your anomalies, you must go to the Mentions tab and take a look at your Volume & Reach chart. When you spot an exclamation mark, just click on it. Because that’s the anomaly!

Imagine having a personal assistant who knows everything about your brand’s sentiment, performance, competition, and audience. Cool, right?

That assistant exists! Meet AI Brand Assistant, one of Brand24’s most exciting features.

In short, Brand Assistant uses advanced language models to transform your project-related questions into data-driven insights.

It works similarly to ChatGPT but has an edge: it can access your project’s data.

So, if you need someone to explain all the numbers from your project in an easy-to-digest way, just ask Brand Assistant.

For example, I asked him about the overall sentiment towards Rihanna’s Fenty Hair product launch. The Brand Assistant’s answer was incredibly insightful!

Ok, I could talk about Brand24’s sentiment analysis features over and over again.

But I don’t want to get you bored, and we must move on to other tools!

So, check Brand24 features by yourself.

• Real-time sentiment analysis

SentiStrength uses two scores because psychology research has revealed that people process positive or negative sentiments in parallel.
