Built around how you already work

You don't have to change

Most tools hand you a system and expect you to bend around it. Ours asks how your head actually works, then builds around that. You are not doing life wrong. You have just been handed boxes that were built for somebody else.

A two minute quiz, then about half an hour with Claude. Free, and it stays free.

It asks. You answer.
That is the whole setup.

You do not have to build anything, and you do not need to understand any of it. There is nothing to learn, nothing to move across from somewhere else, and nothing happens that you have not said yes to first.

💬

It asks you ordinary questions

What keeps falling through the cracks. How long you actually get in one go. What you fall back on when you cannot face cooking. One question at a time, in plain words, and there are no wrong answers.

🧩

Then it puts it together for you

You watch it happen and you can stop or change anything as it goes. Nothing is fixed. If something ends up somewhere that does not suit you, you say so and it moves.

🏡

And it stays yours

Free to start, and the extra bits are one off. Nothing charges you every month for something you already have, and nobody can change it on you or take it away.

Every Syster product.
One place to find it.

From physical products in our shop to web apps and digital tools, here's everything under the Syster umbrella.

Free to start

Get the mess out of your head

It asks you a few questions about the way you already work, then sets up a system built to match, using your words for things. You name it. It files your brain dumps into tasks, notes and people, so nothing falls through the cracks. That part is free and it stays free.

From there you add the bits of life you want it handling too, one at a time, one off payments, only the ones you actually want. Over time it stops being a to-do list and becomes the centre of everything, laid out the way you already think. Plenty of the add-ons are free too, like where the money goes, looking after yourself and something to eat. The rest are $19 each, one off.

A two minute quiz, then about half an hour with Claude. You need a Claude and a Notion account, and both have free plans.

Our approach

Why we build differently

Good systems do one thing: they reduce friction so you can focus on what actually matters.

01

Reduce Friction

Good systems make things easier, not more complicated. We strip away what's unnecessary and keep only what matters.

02

Practical & Beautiful

Systems work better when they're thoughtfully designed. We combine functionality with aesthetics that inspire daily use.

03

Tangible Results

Whether it's a magnet on your fridge or a digital tracker on your phone, systems should deliver real, visible value.

Why I created Syster

I'm Kathryn Marie. I've always thought in systems, sketching routines and frameworks to keep my world running. For years I felt like I was failing at life because I couldn't finish the projects I cared about most. A late ADHD diagnosis explained why my brain was wired differently, and it gave me the language, tools, and self-compassion to complete the things I started.

Syster exists because I turned those personal systems into something tangible for anyone who needs structure with heart. Every product, printable, and digital tool here began as a solution I built for myself, and now it's yours too.

What drives me

  • Systems-first mindset: I design holistic flows, not isolated products.
  • Neurodiversity-informed: Tools are built to honour fluctuating focus, energy, and executive function.
  • Finish-line obsessed: Every guide is built to help you see progress, not just plan it.
  • Shared momentum: If it worked in my kitchen, studio, or inbox, it might be the missing piece in yours.
