Step 01
Answer a short quiz
A few focused questions about your situation — no account, no filler. It reads like a consultation, not a form.
The 1guide promise
The science, distilled into a plan that fits you.
We read the complicated, well-evidenced research so you don't have to — then turn it into a short quiz and a plan built around your situation, not the average one. The reasons are in plain language; the sources are one tap away.
One guide live today. Built the same way each time.
How a 1guide works
The same method behind every guide.
One model, applied to one real problem at a time: distill the evidence, then tailor it to the person in front of it.
Step 02
Get a guide built for you
We weigh your answers against the research and hand back a plan in plain language. Every recommendation names its reason; the studies are one tap down.
Step 03
Go deeper if you want
An optional membership adds ongoing guidance as your situation changes. The guide you get stands on its own — that part is yours to keep.
The guides
One guide live. Each new one, the same standard.
We'd rather ship one guide that genuinely earns its place than a shelf of thin ones. Here's what's live today, and how the rest are being built.

Skincare for Men
Better skin without becoming a skincare guy. A short quiz turns dermatology research into a routine built around your face, not the average one.
Built on Peer-reviewed dermatology, AAD guidance, and PubMed sources.

The next guide
We're building 1guide the same way each time — pick one real problem people actually have, distill the research behind it, and tailor it to the person. When the next one clears that bar, it'll show up here.
Standard Evidence-led, plainly written, tailored.
Evidence, shown
We cite our sources. That's the whole posture.
Distilled doesn't mean dumbed down. It means we did the heavy reading so the answer fits on a card — with the studies underneath it, not hidden from it.
- Every claim names its reasonWe lead with what changes for you, then give the one plain reason behind it. No hand-waving, no authority-by-tone.
- The sources are one tap awayPeer-reviewed research, professional-body guidance, and the primary studies — linked, so depth is always available if you want it.
- We show the work, not a performanceNo fabricated numbers, no invented testimonials, no borrowed logos. When we don't know something yet, we say so.
