From elementary school through college, VEXcode is a coding environment that meets students at their level. The intuitive layout of VEXcode allows students to get started quickly and easily. VEXcode is consistent across Blocks and Text, across VEX GO, VEX IQ, and VEX V5. As students progress from elementary, middle, and high school, they never have to learn a different blocks, code, or toolbar interface. As a result, students can focus on creating with technology, not trying to navigate a new layout. Drive Forward is the new Hello World We all know that robots attract kids to learn. VEX Robotics and VEXcode are providing opportunities for students of all ages to participate in learning the code that makes these robots work. VEX makes computer science come to life through collaborations, hands-on projects, and engaging experiences. From classrooms to competitions, VEXcode helps to create the next generation of innovators. Drag. Drop. Drive. VEXcode is the perfect platform for those new to coding. Students use the simple drag and drop interface to create functioning programs. Each block's purpose can easily be identified using the visual cues like its shape, color, and label. We've designed VEXcode to allow those who are new to robotics to get their robot up and running faster. Now, students can focus on being creative and learning computer science concepts, not stuck trying to figure out the interface. More accessible than ever VEXcode even helps across language barriers, allowing student to read blocks and comment programs in their native language. Drag & Drop. Powered by Scratch Blocks. Students and Teachers will feel instantly at home with this familiar environment. Video Tutorials. Grasp concepts faster. Built-in tutorials cover every aspect needed to get up to speed fast. And more tutorials are coming. Help is always there. Getting information on blocks is fast and easy. These resources were written by educators, in a form both teachers and students will grasp quickly. Drivetrain Blocks. A breakthrough in simplicity. From driving forward, making precise turns, setting speed, and stopping precisely, VEXcode makes it easier than ever to control a robot.

The app for KAI: The Artificial Intelligence Robot STEM Experiment Kit: Safely explore and understand AI and the future of advanced computing technology. With the physical expeiment kit, build your own six-legged, artificial intelligence robot that moves by reacting to the gestures and sounds that you make! There are three steps to create a functioning AI model that allows you to control your robot using poses or sounds: 1. Collect data. 2. Train the AI model with your data. 3. Play with your robot using the AI model. Collect data: Use the app to easily collect the data you need to assign your own movements or sounds to your robot's functions, enabling it to walk, turn, and stop; explore the concept of machine learning as your AI robot learns the gestures and sounds to better perform the assigned functions. Gesture recognition: Choose a gesture or movement to assign to a specific function of your physical robot. For example, you can raise your right arm to trigger the "move right" function. Sound recognition: Choose a sound to assign to a specific function of your physcial robot. For example, you can whistle or clap to trigger the "move right" function. Train the AI model: The data you collected forms a dataset which is then used to create an AI model that your robot can learn from. Play with your robot: Now you can perform the poses or sounds you assigned to various actions and control your robot to move in specific ways! Additionally, the app allows you to play with the robot in remote control mode: - Use the virtual joystick or position sensor of your phone/tablet to move your robot without utilizing any of its AI functions. - Tap on predetermined facial expressions to change the face on the robot’s LED display, or use the draw or text button to customize the facial expression or text that appears on the LED display. The app has been developed to keep your data as safe and private as possible. The app works completely offline, without connection to the Internet, meaning that all calculations are made locally on your device and no image or audio data is stored by the app. This has been confirmed by an independent data protection expert. The full functionality of the app is only available in combination with the physical KAI: The Artificial Intelligence Robot STEM Experiment Kit. ***** Questions or suggestions for improvements: Mail to apps@kosmos.de We are looking forward to your feedback! ****

Verdict

The call

The clearest difference is update cadence: VEXcode GO at every 2 months against KAI Robotics's every 16 months. VEXcode GO also leads on review sentiment (50% vs 27%). KAI Robotics's advantage is rating (3.6 vs 3.2) and device support (3 vs 1). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

KAI Robotics holds the better App Store score, 3.6 against 3.2. Both are backed by a comparable volume of ratings — 22 and 12 respectively. Written reviews complicate that: 50% of VEXcode GO's written reviews are positive against 27% of KAI Robotics's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

VEXcode GO ships an update every 2 months, KAI Robotics every 16 months. Both last shipped on November 3, 2026.
