Cogni - Free-to-use Alzheimer's and Dementia quant self tracker.

Hey everyone — Nelson here, founder of Frontier Humans. My loved ones have been touched by cognitive decline. If you've been there, you know the hardest part isn't the diagnosis — it's the years before it, when you notice something is off but there's no easy way to check. I went looking for a simple tool I could send to a family member. Something quick, private, no doctor visit required. It didn't exist. Every cognitive screening on the market is built for clinicians, gated behind health systems, and invisible to consumers. So we built Cogni. Seven minutes, five tasks based on peer-reviewed research, runs entirely in your browser. No account, no paywall, your data stays on your device. At Frontier Humans we work on getting breakthrough therapies to consumers faster — including NK cell therapies for neurodegeneration. Cogni is the front door to that mission: help people find out early enough to actually do something about it. Would love your feedback. We're especially interested in hearing from anyone who's been a caregiver or has tried to convince a parent to take their brain health seriously. That's who we built this for.
