About Sarenica
Sarenica is an AI-powered mental fatigue and focus optimization tool created by Mukul Singh, a passionate founder with a mission to bring science-backed clarity to modern work.
Founder Vision
After years of late nights, hyperfocus burnout, and data tracking experiments, Mukul Singh developed Sarenica to provide real-time insight into how we feel, focus, and fatigue — using our own behaviors as the input.
Science Meets Simplicity
Blink detection, keystroke pacing, Spotify + Fitbit insights — distilled into a fatigue score and personalized recommendations. We believe mental wellness starts with data you own.
