Life doesn't wait for PMS. But we do.

Niyora is a PMS app that sees your week coming. When feelings run high, it helps you reflect, regulate, and respond, instead of react.

Free · No account · No wearables · No cycle data shared
Your personal details never reach the AI.
Built on one fact

Women with emotional regulation skills handle PMS better.

That's the whole idea. Staying steady is a skill, not something you're born with, and skills can be learned. Niyora teaches it a little at a time, so the week gets easier to carry.

What no one told you

Your hormones are normal. Your brain just feels the shift more.

The difference between a hard PMS week and an easy one isn't your hormone levels. It's how strongly your brain responds to the same normal rise and fall. Two in three women feel it as mood swings.

Same hormones, different response.

When researchers measured them, women who feel awful before their period had the same hormone levels as women who feel fine. The whole difference is sensitivity.

NIMH · Schmidt & Rubinow; Hantsoo & Payne, 2020

It's wired in, and it runs in families.

Premenstrual sensitivity is about 56 percent heritable. The same shift other people barely notice, your system actually feels. A bit like having sensitive skin.

Dubey et al, Molecular Psychiatry, 2017

It has an end date.

When researchers switched these hormones off, the symptoms cleared. When they switched them back on, they returned. It rolls in, and it rolls out, every cycle.

Moon AI · during PMS

Reflect. Regulate. Respond.

Reflect

See it more than one way.

Tell Moon what happened. When you're upset, your mind locks onto one story. Moon shows you a few other ways to see it, so that one stops feeling like the truth.

Regulate

Get through the twenty minutes.

A big wave of feeling takes about twenty minutes to pass. Moon gives you one small thing to do with your body to get through it, so it doesn't take over.

Respond

Send the one you won't regret.

Worked up, it's easy to say something you'll wish you hadn't. Moon writes a few ways you could reply, so you pick the one you'll feel good about, and actually send it.

Training · before PMS

Build the skill before you need it.

It's easier to stay steady when you've practised it calm. Short, playful lessons show you how to handle different feelings, so the skill is ready when you need it.

At work

Handle the sharp email.

Learn to meet a hard meeting or a pointed message without it costing you the whole day.

Between people

Keep a small thing small.

Read a moment before you react, so a passing friction doesn't grow into something it wasn't.

With your partner

Name it without a fight.

Practise telling the difference between PMS and a real issue, and bringing it up so it lands well.

Real stories

Learn from how others handled it.

Work through real PMS moments and the way each was handled, so the lesson sticks better than any rule.

Couples

Is it PMS, or is it real? Either way, Niyora helps.

The week before your period, your reserves run thin and small things land sharp. It isn't that you love anyone less. When you steady yourself first, there's less to spill onto the people you care about.

PMS or real?

Know which one you're in.

A quick read on whether the feeling is the week talking or a real thing to raise. Both are valid. Knowing which changes what you do next.

Say it well

A message, already written.

Tips and ready-to-send lines for the hard conversations, so a plain ask is easier to meet than a mood to read.

After a fight

Come back from it.

If it blew up, Niyora hands you a short, honest message to reopen it. One rough moment isn't the whole story.

Why not just use ChatGPT

A frontier model keeps you talking. Moon helps you need it less.

General AI is built to hold your attention. That is the opposite of what a hard PMS moment needs. Here is the difference, line by line.

Any frontier model
Moon in Niyora

Built to keep the conversation going. It optimizes for time spent.

Built to finish the loop, then stop. It optimizes for you needing it less.

Agrees with you. That is what keeps you talking.

Shows you the other side on purpose. On your side, even when that means slowing you down.

Lets you vent for as long as you like. Research says venting often makes it worse.

Helps you regulate first, so you respond with something you won't regret.

Gives endless options and keeps going.

Gets you to one response you can stand behind, then stops.

Learns a lot about you, and is built to sound like a friend. That builds dependence.

No sign in, so you are never identifiable. It never calls itself human.

Doesn't know your PMS, and rarely raises how your actions land on others.

Built for your PMS week, and keeps the people around you in view.

No ads, no profile, nothing sold. There is no version of Niyora that makes money from your worst moment.

Research backed

Over 30 science-backed activities. Every one has a paper behind it.

No mystic wellness talk. Just practices drawn from peer-reviewed research, cited so you can read the source yourself. Niyora also recognises how strong your PMS is with a short test, and points to the lifestyle changes that actually move the needle.

and more, every card in Niyora traces back to a source.

Private by design

Built to know almost nothing about you.

Your cycle and your feelings are the most personal data there is. Niyora is built so almost none of it reaches anyone, including the AI. Moon uses AI to write its reflections, so we're plain about exactly what it can and can't see.

No sign in

No account, no login. Nothing you write is ever tied to your name.

Your details never reach the AI

Before your words go to Moon's AI, names and identifying details are stripped on your phone. What is left can't point back to you.

Nothing sold, nothing kept

No ads, no profile, no data sold. Your period dates stay on your device, and are never shared.

Why I built Niyora
Neha Prasad

I went looking for a way through PMS that didn't ask me to change my body.

I'm a doctor, so I started where I trust: the research. And the pattern was hard to miss. Most of what's offered for PMS either medicates it or just tracks it. Very little helps you in the actual hard hour.

Then I found the quieter, stronger thread. The most reliable, least invasive way through a hard PMS week is emotion regulation. Learning to name what you feel, settle your body, and see the thought from a step back. No hormones to take, no device to wear, no data to hand over.

That finding is the whole foundation of Niyora. Everything in the app is one small rep of emotion regulation, done in about a minute. I built it for myself first. Now it's yours.
