About
What is Stack Almanac?
Stack Almanac is an AI-powered supplement advisory platform that learns what works for your body. It combines a conversational AI advisor, a personal correlation engine, and bio-individual recommendations to help you optimise your supplement protocol with data — not guesswork.
Most supplement apps are trackers. You log what you take, and that's where it ends. Stack Almanac is different: it's an advisor first, tracker second. The AI doesn't just record your data — it learns from it, finds patterns, and gives you personalised guidance that improves over time.
The problem with supplements today
The supplement industry is worth over $150 billion globally, yet most people have no idea whether what they're taking actually works for them. Generic advice from influencers and one-size-fits-all recommendations ignore the biological reality: the same supplement affects different people in different ways.
What you need isn't more information — it's personal data. Which supplements correlate with better sleep for you? Which ones improve your energy? Are you taking the right forms at the right times? Stack Almanac answers these questions by learning from your own experience.
Core features
Almanac Advisor
A conversational AI supplement advisor powered by Claude. Ask questions about your supplements, get personalised guidance based on your health data, goals, and biology.
Correlation Engine
Connects what you take to how you feel over time. Surfaces personal patterns and trends that generic research can't capture.
Bio-Individual Recommendations
Tailored to your biology, sex, hormonal cycle, goals, and health metrics. Not one-size-fits-all advice from population studies.
Exception-Based Logging
Only log when something changes — a missed dose, a new supplement, a different time. No daily checklists or tedious tracking.
Stack Score
A daily 0-100 score reflecting your protocol adherence, consistency, and logged well-being trends. One number to track your progress.
Community Stacks
Browse and adopt protocols shared by other users. See what experienced supplement users take and how their stacks perform.
