The evidence provided supports that Mendi uses fNIRS-based neurofeedback to measure prefrontal blood-flow/oxygenation and provide real-time feedback. This type of neurofeedback has some emerging research support for cognitive training, but the evidence shown here is not strong enough to confirm broad claims about improving focus, stress resilience, or mental clarity for all users. The product’s marketing claims appear stronger than the research evidence presented.

Mendi is a neurofeedback brain training system designed to enhance cognitive functions such as focus, decision-making, and emotional regulation. It uses functional Near-Infrared Spectroscopy (fNIRS) technology to measure brain activity in the prefrontal cortex, providing real-time feedback to users. This feedback helps users strengthen neural pathways, improving mental agility and resilience.

The Mendi system includes a headband and a mobile app, which together offer a gamified training experience. Users can visualize their brain activity and track progress over time, making brain training both engaging and effective. Regular use of Mendi is reported to improve focus, stress management, and overall mental well-being, supporting a healthier brain and lifestyle.
