Simmer is a reflective space, not therapy. It listens and asks; it won't diagnose, treat, or advise, and isn't a substitute for a therapist or a crisis service.
Simmer is designed for adults. It isn't intended for anyone under 18.
Some days feel tangled. You want to move forward, but something underneath is quietly in the way — and it builds up over time, sometimes surfacing in how tired or on-edge you feel. This is a small space to slow down and hear what's actually there. It doesn't advise or fix. It reflects your own words back, gently, so you can listen to yourself.
Your reflections live in your own browser — Simmer never saves them to a server. To reflect your words back to you, what you write is sent to the AI model that generates the reply. So the record of your words stays with you; it isn't a sealed diary no one else ever touches.
Above, you can choose whether this device remembers your reflections or forgets them when you leave. In forget mode nothing is written to this device at all — only your choice is kept, and only for this visit.
Meet Digby
He's nine, thirty-three kilos, and mostly asleep. Two walks a day, a special diet, and a deep commitment to lying in whatever patch of sunlight he can find.
Digby is an English bulldog, and if you met him you'd think nothing bothers him. He walks past dogs half his size losing their minds — barking, lunging — and doesn't even turn his head. On a busy street he'll plant himself on a corner and just watch people go by, unhurried, like he's got all afternoon. People stop. They always stop. Half the neighbourhood knows him.
But the unbothered thing is a bit of a front. Digby is one of the most sensitive creatures I know. When I'm upset — before I've said anything, before I even know it's showing — he gets up from wherever he's sleeping, comes over, and rests his chin on my lap. Or puts one big paw on my leg. Then he goes back to sleep, right there, leaning on me. He doesn't do anything. He doesn't fix it. He just decides to be where I am.
I talk to him constantly. Twenty different nicknames, whole conversations. "Hey Digby, I'm busy this morning, ten-minute walk, just pee and poo, please cooperate" — and he does, then trots to the front door when he's done, ready to go home. He has a whole vocabulary of throat sounds for happy, for funny, for I have opinions. When he really wants to tell me he understands, he blinks at me, slow.
Here's why he's on this page. Digby heals the way the best things heal — not by solving anything, but by sitting close while you feel it. He can't advise me. He's never once told me what to do. He just senses the weather in the room and comes to rest his weight against me until it passes.
That's what this space is trying to be. A quiet place that doesn't rush you or fix you — just sits with you, chin on your lap, while you hear yourself.
He's my cure, through all of it. The ups and the downs.
I'm Jin. I trained in health and wellness coaching through Harvard Medical School's programs — more than 400 hours learning the craft Simmer is built on: motivational interviewing, cognitive reframing, the quiet science of how people actually change.
But here's the thing I didn't expect. I use Simmer myself, on the nights something sits uncomfortably and I can't quite name it. I almost always find something I didn't know was there.
I built it because most people can't, or don't want to, or aren't ready to sit across from a coach or therapist — and still deserve a place to hear themselves think. The frameworks a good coach would use, available to anyone, at any hour, for free, kept entirely to yourself.
Simmer is for anyone with something on their mind and nowhere to put it down. You don't need a crisis, a diagnosis, or a reason. If your day left something you'd like to hear yourself think through — it's for you.
