The most secure way to manage OpenClaw with your team

Hey everyone, I’m Mukul, the founder of Sarenica. I built this because I noticed something strange while working with AI tools — I would feel mentally drained even when I wasn’t typing much. The classic “screen time” metrics didn’t capture what was really happening. So I started building a system that estimates cognitive fatigue using behavioral signals like typing speed variation, scrolling patterns, blink duration, and attention shifts. Everything runs locally and stores only numerical estimates — no raw recordings. My goal is to make cognitive energy measurable in the AI-assisted work era. I’d genuinely love feedback — especially from developers, researchers, and heavy AI users.
