The Cognitive Fitness OS · Private alpha · Summer 2026
MYNDE is a daily thinking workout that strengthens the cognitive capacities AI is weakening. Seven question formats. A four-dimension Cognitive Fitness Score. The receipt is in your own thinking — in decisions you make better, in perspectives you can finally hold.
Part 01 · The crisis
Three converging facts from 2024 and 2025. Replicated. Peer-reviewed. Not opinion. The cause is the current technology environment. The decline is reversible — with the right inputs.
A decade-long study of 4.5 million adults found self-reported cognitive disability in young adults rose from 5.1% to 9.7%. The younger cohort drove most of the overall increase.
An American Psychological Association review of 71 studies linked excessive short-form video consumption to reduced memory, weakened critical thinking, and diminished cognitive function — replicated across cultures, ages, and content types.
Across 32 brain regions, users who relied on ChatGPT during writing tasks showed the lowest neural engagement and the worst performance. The mechanism is cognitive offloading. The more we delegate thinking, the less capable of thinking we become.
"Brain rot."
Chosen because the experience is universal. The category that emerges in response is cognitive fitness. MYNDE is the first product built deliberately for it.
The daily ritual
A scenario, a perspective, an assumption, a model, a counter-position, a pattern, an ethical weight. AI asks. You think. AI interrogates the answer specifically. Then you close the app and go live your day.
No feed. No notifications. One scenario, perspective, or pattern — chosen by the AI based on which cognitive muscle needs work today. The kind of question a rigorous mentor would ask, not the kind a supportive friend would.
Your team member misses a deadline for the third time this quarter. The first time you addressed it gently. The second time you set a firm expectation. They've just told you they will miss the fourth one next week. The reason is the same as last time.
What do you do?
Calibrated to your specific answer — never templated. One of five angles: assumption, counter-evidence, perspective, pattern, stakes. Beginners get one. Advanced users get three. The interrogation is the actual product.
Imagine you are the team member, not the manager. What does the manager keep missing about what's actually causing the misses? Name one thing.
Every week the score updates across four dimensions: judgment, perspective, reasoning, ethics. It can go down. That honesty is the point. After 90 days of daily practice, the strong line on your chart looks different from the day you started.
You started in the 30–50 range across all dimensions, like most users. Twelve weeks in, your strongest gain is perspective — driven by 41 counter-position sessions where you updated your view.
Part 04 · The question architecture
Each format exercises a different cognitive muscle. The AI picks the right one for you each day based on your level, time of day, and the dimension that needs the most work. A user never sees the same question twice.
"Your top performer asks for a 30% raise. The budget exists but raising her means you can't raise the two below-average performers. What do you do, and what principle is driving the call?"
"A manager fires an employee for being late to 4 of 12 meetings. The employee is shocked. What is the manager seeing that the employee is not? What is the employee seeing that the manager is not?"
"'Hard work always pays off.' Tap the three words in this sentence that carry hidden assumptions most people never examine."
"Today's model is inversion. Most people ask 'how do I succeed?' The inverted version asks 'how do I avoid failure?' Apply this to choosing where to live."
"State one opinion you hold strongly about how money should be earned, spent, or saved. I will argue the strongest opposite — not a strawman. You have 30 seconds to defend, refine, or update."
"Last month: a 19-year-old gamer signed a $50M endorsement, an obscure historian's book hit the bestseller list, a small Ohio accounting firm was acquired for $200M. What do they share that most people miss?"
"You're managing a small team. Your best performer asks for a 30% raise. The budget exists but raising her means you cannot raise the two below-average performers who have asked for less. What do you do, and what principle is driving your decision?"
Part 01.5 · The boundaries
"This is harder than scrolling. That is the point."
People who want their phone to entertain them will not love MYNDE. People who want AI to do their thinking for them will not love MYNDE. The segment that does love it is large, and self-selecting.
Part 06 · The Cognitive Fitness Score
VO2 max made cardio a category. The Cognitive Fitness Score does the same for the mind. Four dimensions, scored 0–100, updated weekly by Claude against a calibrated rubric. Transparent. Can go down. The user can see exactly which sessions moved which number.
The quality of decisions under uncertainty. Measured by willingness to update views, consistency of reasoning across similar situations, and stated certainty calibrated against subsequent reflection.
The capacity to genuinely hold opposing views. Measured by performance in counter-position and perspective-swap formats. Steelmanning ability, scored.
The depth and rigor of thinking. Measured by multi-step session depth, assumption identification, and the structural quality of responses.
The capacity to navigate situations with no clear answer. Measured by ethical-weight responses, willingness to acknowledge real tradeoffs, and the absence of motivated reasoning.
Spend 90 seconds with MYNDE each day for a year, and you will think more clearly than the version of you that did not. The promise is verifiable. The receipt is your own chart.
Part 03 · Who uses it
If one of these is you, you'll know inside the first sentence.
You already feel yourself getting dumber as AI does more of your thinking. You want your professional edge back.
You watch your child glued to TikTok and quietly panic. You will pay anything for cognitive protection for your kids.
You're 14 to 24. You already know about brain rot. You want to be smart. You want to share your thinking the way you share Wordle scores.
You've noticed you can no longer focus the way you used to. You've tried deletion. You want to use phone time well, not guilt-restrict it.
You read books, listen to podcasts, think about ideas for fun. You're underserved by anything daily. MYNDE becomes your morning ritual.
You're 50+. You've watched parents experience cognitive decline. You want to protect yourself, and the supplements aren't working.
A law firm, consulting firm, investment firm, design studio, agency. Your competitive advantage is the judgment of your people. MYNDE Teams is purchased through L&D, with group fitness scores and anonymized team insights.
