BRNLIT AI is a Swiss neurotechnology startup developing a mobile application that uses personalized light signals to activate focus states in the brain. The platform creates an individualized "light code" based on an initial EEG measurement of the user's natural brain rhythms, then delivers that code as brief light pulses through the smartphone LED.

The system measures a user's alpha-wave profile during an onboarding EEG session and generates a unique photic stimulation frequency matched to their neural oscillatory patterns. Each session lasts 60 seconds and is claimed to induce a focus state lasting up to 80 minutes. The company cites research indicating that personalized light stimulation is significantly more effective than randomized light protocols at modulating alpha-wave activity in the visual cortex.

BRNLIT AI targets consumers seeking non-pharmacological cognitive enhancement for work, study, and meditation. The platform stores EEG data and light codes in user profiles in compliance with Swiss and EU data protection laws, with optional integration into electronic patient records. The company advises users with epilepsy or photosensitivity to consult a physician before use.
