You live side by side, yet barely know how their day felt. One question a night — just speak. Honest words come out, and stay as text between you. Start with just you.
"How was your day?" "Fine, I guess."
Even living side by side, you rarely know what your partner actually felt today.
It's not that anything's wrong. It's just that the inside stays invisible until it's put into words.
Behind that unsaid "fine, I guess," the thing they most wanted to share is often hiding.
KOE is a voice journal where today's feelings stay, just by speaking.
It's beautifully simple.
Answer 3 daily prompts with your voice.
"What made you happiest today?" "What would you praise yourself for?"
— Swipe through the cards and pick the question that fits your mood. No staring at a screen, no typing.
What you say turns into text automatically, and stays as your journal.
Just a few minutes, speaking out loud. The day's feelings are kept, just as they are.
◆ Start with just you.
You don't need a partner to begin — KOE works from tonight.
Answer one question a night out loud, and feelings you hadn't even noticed start turning into words.
"Oh, so that's what I was feeling" — small discoveries that quietly add up, day by day.
On nights when writing feels like too much, speaking comes easily.
Leave a little of today's self behind at day's end. That alone makes the night a bit softer.
◆ Speak, and you're honest. Read, and you're calm.
When you speak, your guard comes down in a way it doesn't when you type.
The unfiltered words that never make it past the keyboard flow out naturally when you just talk.
"I felt a little proud of myself today." "Watching the kids sleep nearly made me cry."
— Words too heavy to type come out effortlessly when spoken.
And what stays and arrives is text.
The sharpness of tone, the exhaustion — all of it disappears in text.
What remains is only what was really meant.
So the one reading it can receive it calmly, without catching on how it was said.
"Ah, so that's what they were thinking" — you can face it head-on.
◆ Together: their "today" comes into view.
Connect with someone close via invite code, and you can read each other's entries.
On days too busy to talk. Days when a reply turns curt.
Even then, what they felt today arrives in words — and that alone brings a little relief.
Less "I have no idea what they're thinking."
More "Oh, so that's how their day went."
The day you couldn't see just by being together slowly comes into view.
【"Diaries never stick" — quietly solved】
The reason journals don't last is usually the effort of writing.
KOE brings that effort close to zero.
3 daily prompts → no wondering "what should I write"
Just answer with your voice → no typing, no overthinking
Only 3 questions → it becomes a daily habit without even trying
Cloud sync keeps you safe through device changes.
Your journal is a private space — just for you, and only whoever you connect with.
【For you, if...】
You've been together a long time, yet feel you barely know them
You want to share how you feel, but writing it out makes it heavy
You want to gently look back on your own day at day's end
You want to fall asleep with a calm heart
A new daily habit — through voice.
Nothing special is needed.
Just 3 minutes before bed, putting today into words.
Start with just you.
Invite someone close whenever you feel like it.
Why not try KOE, starting tonight?
