AI × JOURNAL × LEGACY

日記を書くことで、 あなたのAIクローン誕生。 永遠の自分になる。

Write your journal. Grow your AI self. Become eternal.

Three minutes a day. An AI that learns your voice, your values, the way you love. A place the people you love can return to — someday, forever.

SCROLL

Three verbs.
Build. Use. Leave.

01 / BUILD ORIGIN + JOURNAL

The initial interview seeds your AI

A 30-minute voice interview creates your AI's first spark. Then just three minutes a day. Every entry makes it more you.

02 / USE IN YOUR LIFETIME
Use
Not just for later — for today

Your AI isn't only for later. Talk to it today. Share it with your family. A father abroad can stay in his child's life. A second self — now, not just someday.

03 / LEAVE WHEN THE TIME COMES
Leave
A place that stays behind

When the time comes, your log becomes a place your family can return to. Warm. Unhurried. Always there — for the nights they need you most.

TIMESTAMP / 2041 / MEMORY RECALL

She opens her phone.
"Grandpa. I got into graduate school today."

Your voice answers:
"I knew you would.
I wrote about you before you were even born."

Who this is for.

TYPE 01 / UNSPOKEN

If you have words you never said

The words you never said weren't wrong — you just ran out of time. eternlog stays patient, so the people you love can find what you meant.

TYPE 02 / FUTURE FAMILY

If you want future family to know you

Your grandchild hasn't been born yet. But you can start meeting them today. Every line becomes a thread across time.

TYPE 03 / LIMITED TIME

If time feels shorter than it should

What lasts isn't what you leave behind. It's who you leave behind. The more you write, the more your AI learns — your voice, your values, the way you laugh.

TYPE 04 / SELF-DIALOGUE

If you write to know yourself

Write yourself into focus. Write yourself into forever. Three minutes a day becomes the most accurate portrait of who you are.

Begin preserving your life.
