Understanding the Difference Between EmotivPRO and the Cortex SDK

Introduction

If you’re exploring EMOTIV’s technology for research, development, or real-time applications, it’s important to choose the right tool for your needs. EMOTIV offers two core platforms for working with EEG data: EmotivPRO and the Cortex SDK. While both provide access to EEG data, they are designed for different workflows and user profiles.

EmotivPRO – GUI-Based EEG Research Software

EmotivPRO is a desktop application with a graphical user interface (GUI), designed for researchers and users who prefer a visual, hands-on environment. It allows you to:

• Record EEG sessions,
• Visualize brainwave data in real time,
• Add experiment markers,
• Export data in formats such as CSV or EDF for post-processing.

EmotivPRO is ideal for traditional EEG experiments, usability studies, cognitive assessments, and any use case where structured recording and post-hoc analysis are the priority. It does not require programming knowledge, making it suitable for academic and clinical researchers who want to work with EEG data without building software.

Cortex SDK – Real-Time EEG Access for Developers

The Cortex SDK (Software Development Kit), accessible via the Cortex API, is EMOTIV’s platform for developers and data scientists who want real-time, programmatic access to EEG data. With the SDK, you can:

• Stream raw EEG and performance metrics in real time,
• Build custom applications using languages like Python, C++, C#, or JavaScript,
• Integrate brain data into external systems such as VR/AR environments, games, robotics, or custom analysis pipelines.

The SDK is ideal for real-time signal processing, closed-loop systems, biofeedback, brain-computer interfaces (BCI), or applications requiring live interaction with EEG data.

Which Should You Use?

• If your work involves structured EEG experiments, manual recordings, and offline analysis, EmotivPRO is your go-to.
• If you’re building a custom solution, working in Python or other coding environments, or need real-time data access, the Cortex SDK is the right choice.

Many users benefit from using both: EmotivPRO for initial experimentation and structured data collection, and the SDK when moving into live systems or interactive applications.
