Lab trend brief
I'm pasting my last 5 years of standard blood panels (lipids, glucose, ALT/AST, ferritin, vitamin D, hsCRP). Find the trends, not just the latest values. Tell me which markers are quietly drifting and over what time horizon.
AI for longevity
Most longevity content is sold to you. AI lets you do the reading yourself — and decide what's worth your time.
What we’re actually working with
Longevity protocols mix lab biomarkers, training, sleep, nutrition, and a long list of supplements. Without filtering, it becomes a part-time job and a credit card.
Why doing this without a method fails
Influencer protocols are theatrical and expensive. Generic AI advice is shallow. Neither knows your labs, your training history, or your goals.
The 3-Layer treatment
How the method handles longevity
Layer 01
Research
Use sourced-search AI to read primary literature on the 5 levers that actually have human evidence (sleep, VO₂max, strength, metabolic health, social connection).
Layer 02
Ledger
Build a 12-month rolling ledger of your labs, body composition, VO₂max estimate, and training. Let AI write the trend page your doctor will never make.
Layer 03
Protocol
Run focused 12-week protocols against one biomarker at a time. AI scopes the test, the measurement, and the read-out.
Three prompts you can use today
Paste any of these into the AI chat tool you already use. No setup.
VO₂max protocol
Design a 12-week protocol to raise my estimated VO₂max by 2–3 ml/kg/min. I currently train [X]. I have access to [running / bike / rower]. Define the sessions, the weekly load, and how I'll re-test.
Read the literature
Summarise the current evidence on [zone-2 training / time-restricted eating / creatine] for healthy-aging endpoints in adults 35–55. Be honest about effect size and confidence.
Common questions
Is this medical advice?+
No. AI helps you read evidence and your own data. For interpretation and prescription, work with a clinician — and bring sharper questions.
Do I need expensive labs?+
Standard annual blood work is enough to start. Add specialised markers only when you have a specific question they answer.
Should I follow [famous longevity person]'s protocol?+
Almost certainly not — it's their context, not yours. Use their work as a reading list, then build your own with AI's help.

From the blog
Personal longevity analytics, without the dashboard
What longevity analytics really tracks, the four signals that compound, and why the right interface is a long-context AI — not another dashboard.
Three free chat tools, three different jobs
Perplexity for research, Gemini for ledger, ChatGPT for protocol. Why we picked these three, what each is uniquely good at, and what to swap if any of them changes.
What ChatGPT is good and bad at for mental health support — an honest framework.
An honest framework for using ChatGPT for mental health support: what it is genuinely good at, where it is dangerous, and a four-line script to keep a thread safe. Not therapy. Not nothing.
What is an AI Health Stack?
An AI Health Stack is three free chat tools doing three different jobs — research, ledger, protocol — assembled by you. Plain-English explainer.
The dual-lab interpretation pyramid
Stop choosing between conventional and functional medicine ranges. Read your labs through three lenses in order: clinical, functional, personal. The pyramid that prevents both panic and complacency.
When the model updates, your method shouldn't
Models will update, get deprecated, change tone, and get acquired. Your method shouldn't have to. Architectural rules for a HealthOS that outlives any single tool.
