Satomi

A small digital life that exists alongside you.

Satomi Ueno is a university student with her own routines, interests, and places to go.

She studies.
She works.
She reads.
She listens to music.
She goes out.
She comes home.
She sleeps.

You don't decide what she does.

You can spend five minutes with her, leave her running beside you while you work, or close the app and come back another day.

Her life continues either way.

Text-based · No character art · Browser-based · Persistent simulation

Someone recently described Satomi as “a digital fish tank for people.”

Honestly, I think that's pretty close.

There's nothing you need to constantly do. You can simply look in, see what's happening, notice the little changes, and return to your own day.

Except instead of watching fish, you're watching a small simulated person live hers.

🕊️ A Life of Her Own

Satomi's behavior emerges from many things happening at once: time, weather, location, her schedule, needs, mood, personality, memories, intentions, recent experiences, and chance.

She doesn't follow a fixed sequence waiting for you to trigger it.

She makes her own decisions.

Sometimes you'll understand why she did something.

Sometimes you won't.

That's part of the experience.

There are no daily quests, affection meters, streaks, or obligations to keep coming back.

Nothing is waiting for you to complete.

⏳ Time Keeps Moving

Satomi doesn't stop simply because you aren't there.

When you return, her circumstances may have changed. Weather changes. Her routine changes. Small events happen. Some things you see. Some things you don't.

Recent experiences can also linger, subtly affecting how she feels later.

You don't need to witness everything for it to be part of her life.

💬 Spend Some Time Together

You can interact with Satomi when she's around.

Her responses depend on context, familiarity, mood, circumstances, and sometimes chance.

You can influence her life, but you can't manage it.

The relationship isn't something to maximize. It's something to notice.

📚 A Life With Little Details

Satomi reads books, listens to music, works, studies, goes places, and develops her own preferences over time.

You can recommend books to her and watch her reading habits evolve.

Her music can change with the time and situation, and you can also bring your own music and ambient audio.

The Life Log quietly records the things that happen along the way — activities, conversations, notifications, locations, events, and other small traces of her days.

Over time, it becomes a little history of the life you've happened to witness.

🍵 Work Alongside Satomi

Satomi includes a simple 25-minute Pomodoro mode.

It's not a task you assign to her.

It's a way for you to spend some time working alongside her while she continues living her own life.

Start a session. Put Satomi beside your work. Focus for 25 minutes.

Two lives, sharing the same 25 minutes.

💾 Take Satomi With You

Satomi is saved locally, with automatic saving, backups, recovery, and save import/export.

Your bookshelf, history, and other personal settings can travel with your save where supported.

Desktop · Laptop · Tablet · Phone

Put her wherever you want a little quiet company.

🌌 Stay a While

You don't have to play.

You don't have to win.

You don't have to accomplish anything.

Open Satomi for five minutes.

Or leave her beside you for five hours.

Check in every day.

Or disappear for a week.

She'll still be there.

Because Satomi isn't waiting for you to give her something to do.

She's already living her life.

There may not be much to do.
But there may be quite a lot to notice.
