Measure Your Brain. Train It. Track Progress.
Sens.ai measures how your brain is working, helps it improve, and tracks your progress. For practices and at home.
The Brain and Longevity
Longevity medicine measures almost everything about the body: blood markers, DEXA, VO2 max, sleep and HRV. The brain is usually missing, even though a 2025 study of 11 organs found the brain's age was the best single predictor of how long people live.
Function changes first, often years before anything shows up on an MRI. That early window is when change is still possible.
Measuring the Brain at Work
Someone walks toward you with an arm half-raised. Handshake or hug? In about half a second your brain filters what it sees, classifies it, decides and acts. Sens.ai measures that sequence as it happens, to the millisecond: a treadmill stress test for the brain, rather than a resting pulse.
Select a step to see where it happens.
- 143 msAn arm starts to rise.Early sensory response.
- 255 msHandshake or hug?Sorting the stimulus.
- 389 msHandshake.Choosing the response.
- 395 msYou reach out.In the assessment, a button press.
Brain's electrical response (ERP)Time after stimulus, one response
Illustrative values for a single response. As the brain ages, the later, decision-making responses slow while the earliest sensory response barely changes. Sens.ai measures each one.
Measurement and Intervention in One System
A score without a next step leaves people unsure what to do. Sens.ai connects the measurement to an intervention, then tracks your progress.
- 1AssessSee how your brain is working now, measured under load while it filters, decides and responds.
- 2InterveneFollow an at-home intervention, called a Mission: a structured 5- to 12-week protocol of neurofeedback training and photobiomodulation (gentle near-infrared light), matched to your results and goals.
- 3Track ProgressTrack your progress two to three months later, after the at-home Mission, and choose what comes next.
Two Ways to Use Sens.ai
One platform, two ways in: through a practice, or on your own at home.
For PracticesAdd the brain to your longevity panel, starting with BrainYears™ powered by Sens.ai: a functional brain age from a 20-minute assessment, and a personalized protocol to improve it.
At HomeThe only at-home closed-loop system that combines brain stimulation, brain training and objective brain function assessments.
The Research
BrainYears™ powered by Sens.ai matches gold-standard MRI accuracy using a headset instead of a scanner.

5.18BrainYears™
In a real-world study pre-published on bioRxiv, participants who trained with Sens.ai reversed an average of 5.18 BrainYears in 56 days. A 28-person intervention group against a 22-person minimal-exposure comparison group, co-authored by Sens.ai and Buck Institute researchers. Non-randomized and self-selected. Those who didn't adhere to the protocol showed no meaningful change.
Developed in collaboration with the Buck Institute for Research on Aging
