The problem

Supplement advice is broken.

You don't need more information. You need a plan that actually fits you.

Reddit threads at 2am
Six tabs open, two contradicting each other, one guy who calls himself "Brodybuilder42" insisting you need 14 different things.
Amazon reviews that say nothing
"Five stars, will buy again." Cool. Tell me if it actually helped your skin or your sleep. Anyone? Bueller?
"Just take a multivitamin"
Generic advice for generic problems. Your goals, your diet, your body — none of that gets factored in.

How it works

Three steps. No spreadsheets.

1
Tell us your goals
A short, conversational onboarding — skin, sleep, muscle, energy, longevity, whatever you're optimizing for. Plus your diet, habits, and anything you already take.
2
Get your protocol
A prioritized stack of supplements and peptides built around your inputs. Doses, timing, and the reason each item is on the list. Items you should drop, too.
3
Check things off daily
Ten seconds in the morning. Streaks, restock alerts when you're running low, and contextual tips that explain why each item is doing what it's doing.

What you actually get

A real stack. Not a list of vitamins.

Here's a sample protocol for someone whose top goals are clearer skin, better sleep, and more energy.

Six items, organized by time of day, each tied to a specific reason from your inputs. No fluff, no upsells, nothing to combine that shouldn't be.

Why these items? Diet inputs (low fatty-fish, no organ meat) + goal inputs (skin + sleep) drove the picks.
Why this timing? Zinc and magnesium fight for absorption — different slots. D3 works better with morning sun. Glycine before bed for sleep depth.
Peptide-aware. Already on BPC-157, NAD+, or a GLP-1? Add it during onboarding and the engine factors it in.

Why it's different

A real plan. Not another list.

Built by people who actually take this stuff
No generic "take a multivitamin" advice. Real-world stacks that actually move the needle — supplements and peptides included.
Supplements and peptides, in one stack
BPC-157, GLP-1, NAD+, glycine, EPA — we don't care if it comes in a capsule or a vial. If it belongs in your protocol, Kai tracks it.
Real recommendations from your diet & goals
Heavy meat eater? You probably need glycine. Vegan? Different gap. We figure it out from what you tell us.
Knows what NOT to take together
Zinc and magnesium fight for absorption. Iron and coffee, too. Kai handles the timing so you don't have to.
No ads. No upsells. Ever.
Trust beats ads. We'll never sell your data or shove sponsored brands into your stack.

Questions

The stuff people actually ask.

Is this medical advice?

No. We're not doctors and we don't play one in an app. Kai helps you organize and track what you take based on your goals — the same way a thoughtful friend who reads the research might. For anything you're unsure about (existing conditions, medications, pregnancy, peptides), talk to your actual doctor.

What about peptides like BPC-157, GLP-1s, or NAD+?

Kai tracks them the same way as anything else — name, dose, timing, and the reason it's in your stack. We don't sell, prescribe, or source peptides. Where and how you get them is your call (and your doctor's). If you're already on one, add it during onboarding and the engine factors it in.

How is this different from Cronometer or MyFitnessPal?

Those are great for tracking what you ate. We work the layer above — what you should be adding on top of your diet, when to take it, and what not to combine. Different problem, different tool.

Do you sell supplements?

No. Never. Selling supplements would compromise the advice. We charge a flat subscription and that's it — no affiliate links, no sponsored brands, no “recommended” products that just happen to pay us.

I already take a bunch of stuff. Will it just pile more on?

Opposite — onboarding asks what you already take, and the engine deduplicates, flags real gaps, and surfaces interactions. The most useful output for a lot of people is “you can drop these three.”

When does it launch?

We're heads-down on it. Drop your email and we'll send you the link the day it ships — no marketing drip, no promo emails between now and then.
