Hume Expression Measurement
Hume Expression Measurement is an emotion AI tool that helps identify and measure human emotions. It works through a single API and uses four types of data: voice, images, video, and facial expressions. Together, these offer a deeper and more detailed look at how people express emotions.
Real-life experience
This emotion recognition software may not always be 100% accurate, but it captures emotional nuances effectively, especially through speech patterns. However, it’s not perfect. Sometimes, it may not detect basic emotion from vocal bursts. Still, the emotional results often feel realistic and nuanced.
Hume is best for users who want a detailed and responsive look at emotional behavior, not just simple labels like “happy” or “sad.” The web application for the emotion recognition software is extremely user-friendly.
Key features
- The software provides a real-time analysis for emotions, sentiment, and toxicity for a given text.

- This emotion recognition software also detects emotions from videos, images, and audio documents. Users might upload documents, or they may prefer to use their own camera and speakers for emotion detection.
Hume analyzes speech, images, and videos using several features:
- Facial expression: Detects facial movements to understand facial emotions like joy, anger, or sadness.
- Vocal burst: Measures how someone sounds, whether calm, excited, stressed, etc.
- Speech prosody: Tracks changes in tone, pitch, and rhythm. This helps identify the emotional tone of what someone is saying.

- Psychologist review: Trained psychologists review the AI results to find hidden biases and emotional triggers. This adds valuable insight to AI analysis.
RightFlow
RightFlow is an emotion AI tool that analyzes facial expressions to understand how people feel during their experience with a brand. It helps businesses capture emotions like happiness, anger, fear, or surprise to improve marketing, customer service, and product design.
Key features
- Hot zone detection: Identifies where people spend time and what grabs attention.
- People count: Tracks how many people interact with a space or product.
- Demographic analysis: Captures age and gender to understand audience differences.

Unlike tools focused only on emotion detection, RightFlow combines emotion data with customer counting, demographic tracking, and physical safety features. It’s designed for public spaces, stores, or events where real-time, contact-free analysis matters.
MoodMe Face AI Emotion Detection Engine
MoodMe’s Face AI Engine is a tool that reads facial expressions to detect emotions in real time. It works directly on the user’s device, with no internet connection or cloud processing needed.
Key features

- Face matching: MoodMe includes a built-in tool for face identification. It can match a face to stored templates locally for secure identity checks.
- Unbiased and inclusive: The AI is trained on diverse data to avoid favoring any group. This ensures fairer results across different faces and expressions.
- Privacy-first: All processing happens on the user’s device. Faces are never stored or sent to the cloud. This protects privacy and meets strict data regulations.
MorphCast MyMoodScan
MyMoodScan is a free web emotion detection app by MorphCast that analyzes facial expressions to uncover hidden emotions. You can upload a photo or use your device’s camera to see real-time emotional feedback.
Real-life experience:
The app is enjoyable but not always accurate. Sometimes it mislabels emotions such that happy faces might be tagged as apathetic or longing, and disgusted expressions might show as surprised. Still, it’s a lighthearted way to start thinking about the complexity of human emotions.
In short, MyMoodScan stands out for its real-time, social-friendly approach to emotion detection, even if the results can be a bit playful rather than precise.
