A journey to possibilityConceivable
AI fertility intelligence

Your body,
finally
understood.

Every other app hands you data and walks away. Kai reads your cycle, labs, wearable and symptoms, then tells you what's going on, in plain language, and what to do about it this week. Periods, fertility, every chapter after.

Your luteal phase ran short twice this year. That's worth looking at, here's what I'd track next cycle.

The problem

Trackers collect.
They don't care.

You log for months. It gives you a chart, a ring, a streak. It never says the one thing you actually opened the app for.

Every other app

A beautiful wall of numbers

Cycle length 24 d
Resting HR 62 bpm
Sleep score 78
Logged symptoms 31

All true. All meaningless on their own.

Conceivable

A team that reads it, then tells you what to do

Your last three cycles ran 24, 23 and 25 days, shorter than your baseline.
Paired with your low progesterone, that points at a short luteal phase. It's common, and it's addressable.
So what do I actually do this month?
Three things. I've put them in your plan, in order, with why each one matters.

Kirsten's AI.
25 years of her, in your pocket.

“I spent 25 years learning to read these patterns. Kai is that reading, available to you at 3am, in your own home.”

25 years
In practice

Kirsten's clinical pattern recognition, encoded, not scraped from the internet.

10,000+
Cases behind her

Every pattern Kai reads has been seen before, by someone who was in the room.

24/7
Available

The 3am question gets a real answer, not a waiting-room appointment in five weeks.

She never guesses

When your data can't answer the question, Kai says so, and tells you exactly what to log next.

Ask Kai anything
Wherever you're starting

Wherever you are,
we're already there.

Trying, not trying yet, or just tired of not knowing. Kai starts from where your body actually is.

Portrait, light through glass
Actively trying

Trying now

You're timing everything and still guessing. Kai narrows the window with your own signals instead of a textbook 28-day average.

Ovulation confirmed from temperature and LH, not calendar math

Kai: your window opens in 2 days, earlier than last cycle.
Your score

Your score isn't a verdict. It's a starting line.

One number, built from everything your body is telling us, and it moves with the work you put in.

Bring everything

Upload anything. Kai knows your story.

A decade of lab results, a photo of a scan, a clinic letter you never understood. Drop it in, she reads it and holds it in context from then on.

Food as protocol

Meals built for your root causes

Not a generic fertility diet. If your thyroid is the issue, you get thyroid meals. If it's insulin, you get insulin meals.

Iron-forward breakfast Low ferritin
Slow-carb lunch Insulin
Selenium + brazil nuts Thyroid
Done for you

Shopping, ordered by aisle

Your plan becomes a list you can shop without thinking. The decision fatigue is the part we removed.

Wild salmon · 2 fillets
Brazil nuts · small bag
Lentils · dried, 500g
Spinach · two bunches
Your week, handled

The week, the recipe,
the list. Done for you.

Your protocol arrives as seven days of meals, the recipes behind them, and one list to shop. Swap anything and the rest re-plans itself.

01 / The week Sunday

Seven days, planned

Mon · iron-forward breakfast
Tue · slow-carb bowl
Wed · selenium + salmon
Thu · lentil braise

Built from your protocol, not a generic meal plan. Swap any day and the rest re-plans.

02 / The recipe Any day

Why this meal, exactly

Wild salmon, 180g
Brazil nuts, 3
Spinach, two handfuls
Olive oil, cold

Every recipe says which marker it's aimed at, so nothing feels arbitrary.

03 / The list Before you shop

One list, by aisle

Produce · spinach, lemons
Fish counter · salmon x2
Dry goods · lentils, nuts
Dairy · live yoghurt

Combined across the week, ordered by aisle. Check off as you go.

Halo ring

Temperature, sleep, HRV and glucose, gathered while you sleep, and read against your cycle, not in isolation.

Adaptive tracking

What it watches for you
changes as you do.

The signals that matter in month one aren't the ones that matter in month nine. Kai moves the spotlight so you're never tracking things for the sake of it.

Months 1-2

First, we just learn your baseline

Nothing to optimise yet. Kai watches the handful of signals that establish what normal looks like for you, and ignores the rest.

Cycle length + variation Watching
Basal temperature Watching
Sleep consistency Watching
Everything else Muted
One app, every chapter

She grows with you.
Pick your chapter.

Conceivable is one app with six lenses, from a first period to menopause. Change the lens and the whole app, Kai included, reshapes around where you are.
