Introducing Stack Almanac: Your AI Supplement Advisor

Stack Almanac launches today. An AI-powered supplement advisor that doesn't just track what you take, but helps you understand what actually works.

product releases

Supplement routines are confusing. There are thousands of products, contradictory advice, and most apps just give you a checklist. You log what you took, and that's it. No one tells you whether any of it is working.

We built Stack Almanac to change that. It's not a tracker with an AI bolted on. It's an advisor first, with tracking built around it.

An advisor that knows your routine

At the heart of Stack Almanac is the Almanac Advisor, powered by Claude. It has full context on what you take, when you take it, and how you're feeling. Ask it anything: whether two supplements conflict, what time to take magnesium, or whether your current routine makes sense for your goals. You'll get an answer grounded in your actual data.

This isn't a generic chatbot. It's personalised from day one.

Effortless tracking that stays out of your way

We know nobody wants to tap through a checklist every morning. Stack Almanac uses smart defaults: if you don't say otherwise, we assume you took your supplements as planned. You only need to log the exceptions: a missed dose, a change in timing, or a new addition.

The result is a complete compliance history without the daily chore.

Your Daily Score

Every day, Stack Almanac calculates a Daily Score based on your logged outcomes: energy, sleep, mood, focus, and more. Over time, this score becomes the foundation for personal insights: which supplements correlate with your best days, and which ones might not be pulling their weight.

Everything else in v1
