How Your Health AI Thinks
Named after physicist David Deutsch, DEUTSCH doesn't guess - it creates knowledge through a rigorous process that mirrors how scientists think.
Generate
Creates multiple possible explanations for your symptoms, biomarkers, or health patterns. Not just one answer - many possibilities.
"Your fatigue could be from iron deficiency, thyroid issues, sleep apnea, or stress. Let's investigate each one."
Verify
Checks each explanation against medical evidence and your personal data. Some ideas survive, others don't.
"Your iron levels are normal, so that's ruled out. But your TSH is borderline - thyroid needs a closer look."
Reason
Debates the surviving explanations to find the one that best fits your unique situation. Like doctors consulting each other.
"Considering your sleep patterns and stress markers, subclinical hypothyroid + cortisol dysregulation is the strongest theory."
Score
Rates how "hard to vary" each recommendation is - meaning how reliable it is. Low-confidence answers are flagged.
"High confidence: Morning light exposure will help. Moderate confidence: Magnesium may help. Uncertain: Discuss T3 with your doctor."
Why This Matters
Unlike typical AI that just predicts the most likely answer, DEUTSCH actively tries to prove itself wrong. What survives is more likely to be true - and helpful for your health.
Your Doctor Stays in Control
Named after philosopher Karl Popper, POPPER is a supervisory agent that watches every recommendation - ensuring nothing reaches you without proper safety checks.
The Only Health AI with a Supervisory Agent
Regain is the only company with POPPER - a dedicated safety agent that watches every AI recommendation before it reaches you.
AI Proposes
DEUTSCH creates recommendations. It doesn't act on its own - it proposes ideas for review.
POPPER Checks
Every recommendation passes through POPPER's safety evaluation. Approve, Route, or Hard Stop.
Uncertain? Escalate
When AI is uncertain, it says "I don't know" and routes you to a real clinician. No guessing.
Humans Decide
Your doctor reviews AI suggestions and makes the final call. AI is a tool, not a replacement.

You Can See the Reasoning
Unlike black-box AI that just gives answers, Regain shows you why. Every recommendation comes with transparent reasoning you can understand.
Show Your Work
Every recommendation shows the reasoning behind it. What evidence was considered, what was ruled out, and why this answer won.
Ask "Why?"
Tap any recommendation to ask "Why?" and get a plain-English explanation. No medical jargon unless you want it.
Confidence Levels
See how confident the AI is. High confidence, moderate, or uncertain - you always know where things stand.
"The best AI doesn't hide how it thinks - it shows you. That's how trust is built, one transparent recommendation at a time."
