A rainy day's flutter of anticipation
JoyfulIt's pouring today, and somehow I've felt a little excited since this morning. One thing I like about myself: I love every kind of weather—clear or cloudy, windy or rainy, even snowy. But rainy days are my favorite. They simply make me happy—damp and quietly romantic. So today I have a feeling something good is about to happen.

Problem
Feelings are fleeting, but journaling always gets put off
The moments that move us arrive all of a sudden. Right after a meeting, on the way home, before falling asleep, when someone's words linger. But writing in those moments isn't easy. Momentary was made so you don't miss those very moments.
When a blank page feels heavy
You don't have to agonize over the first sentence.
When emotions are complicated
Momentary calmly organizes the feelings you put into words.
When a thought just passes by
Capture it the moment it comes, and look back on it later.
When you want to know yourself more
Through your collected moments, you can see the flow of your emotions and thoughts.
Solution
Momentary turns your words into moments — and uses those moments to understand you
You don't need perfectly polished sentences. Just say what you feel right now, a thought that just surfaced, or something hard to put into words. Momentary turns your voice into a complete moment — title, mood, keywords and body — and from those moments becomes your own mentor, looking back on past moments with you.

Reflection question
Where does the little thrill I feel on rainy days come from?
It's really pouring today. But somehow I've felt excited and hopeful since morning. One thing I like about myself is that I love every kind of weather—sunny, cloudy, windy, rainy. Especially rainy days. They just feel good—damp and romantic. I have a feeling something nice will happen today.
How It Works
Just focus on the moment of speaking
Momentary is designed so you can start journaling at the very moment a feeling or thought arises. When you start recording, the screen switches to a dedicated view — leaving only a live waveform, the elapsed time, and a done button — so you can focus on the thought at hand.

A warm line while you wait
While Momentary transcribes your voice and creates the journal, it shows a short, warm line based on what you just said.

Reflect
Your collected moments become a conversation that helps you understand yourself
Momentary's AI mentor looks back on your current emotions and thoughts together with you, based on the moments you've left. If you have an entry from today, it centers on today's flow; if you have recent entries, it offers a more contextual reflection based on your most recent moments. You can reply by voice or by text. When you want to keep going out loud, use your voice; when you want to take your time, write it out.

Personalization
A line that remembers you, each time you return
Momentary doesn't end at simply storing your records. PRO users receive a warm home greeting tailored to who they are today, based on their recent moments and reflections.
The more your records grow, the more gently Momentary welcomes your day.
Today's greeting
PROIn your recent records, I sensed both anticipation for a new start and a little tension. Today, rather than doing it perfectly, it's okay to focus on starting small.

From the founder
The person who built this app
Momentary began in the summer of 2023, in the time of saying goodbye to Minam, the cat who had been my companion for twenty years. For a year and a half I stayed home, and the voice diary I recorded while crying without a sound became the app's very first form. Even after Minam was gone, I kept writing in it every day for two years, then let it sit untouched for a while — and recently I brought those records back to life as a complete app. I hope many of you come to feel the same fullness I felt while using Momentary.

Privacy
Because your records deserve to be handled with care
Momentary is a space for private thoughts and emotions. Journals and voice recordings are material for understanding yourself — not something to be judged or evaluated.
Records only you can access
Your journals and voice files are managed so that only you can access them.
Voice managed too
When you delete a journal, its linked voice file is deleted as well.
Reflection over judgment
Rather than labeling or evaluating emotions, Momentary helps you look inward through open questions.
Try saying the feeling you have right now, out loud
It doesn't have to be perfectly sorted out. Momentary will help bring together the emotion and meaning in your words, right now.
