About Ever Journal

Everyone has a life worth a book.

Ever Journal is where you write your biography with Eve, an AI biographer. She interviews you one good question at a time, and every answer you give becomes part of your book.

Who makes it

Ever Journal is built by its founder, Yosuke Sakurai, and sold by Code Your Reality, a software business based in Japan. Yosuke Sakurai also writes the blog, about writing a life and what we're learning as we build Eve.

How Eve writes

Eve writes only from what you tell her, plus light historical context about places and years, which she labels. Anything she doesn't know is marked as a gap, never invented. Every sentence is checked against your own words before you see it.

You approve every change. Eve shows what she added and where it came from, every paragraph links back to the entry it came from, and you can undo any change exactly.

Your story stays yours

  • Private by default. Only you can read your book. Nothing is shared or published unless you choose to.
  • No training on your story. Eve's writing is done by AI models under terms that don't allow training on your data.
  • Topics you choose to skip, she skips. Change them anytime.
  • Yours to keep. Download everything (your book, entries, photos and recordings) whenever you like, or delete it all.
