The AI-powered life-history journal
Tell your story.
It writes your history.
No forms. No fields. Just talk — type or speak in plain sentences like "I lived at 123 Main Street from 2003 until December of 2014." The AI listens, asks the questions a good biographer would, and turns your answers into rich prose and a beautiful, scrollable timeline of your life.

You don't fill out a form.
You have a conversation.
Say it the way you'd say it to a friend. The AI picks out the who, where, and when — then asks the thoughtful follow-ups that make a memory worth keeping.
Adding an entry…
I lived at 123 Main Street from 2003 until December of 2014.
Got it — almost twelve years on Main Street. What made that house home? Who lived there with you?
We moved in right after we got married. Both of our kids were born while we lived there.
That's a big chapter — newlyweds to a family of four. Is there a moment in that house you never want to forget?
Teaching the kids to ride bikes in the driveway. And the huge maple tree out front every fall.
✓ Saved to your Where I Lived thread
…and when you come back, you don't get your words played back to you. You get something like this:
The house at 123 Main Street was where your life changed shape. You arrived in 2003 as newlyweds, and over the next eleven years it became the backdrop for your family's first chapter — both of your children were born while you lived there, and its driveway is where they learned to ride their bikes.
When you picture it now, it's autumn: the great maple out front turning, the house behind it full. You closed that chapter in December of 2014 — but on your timeline, it's never far away.

Kind words
"I just talked about my first apartment for two minutes, and it asked me things my own kids never have. What it wrote afterward made me a little emotional, honestly."
"It's the memoir I always meant to write, except it builds itself as I go."
"Adding my old cars and where I lived turned into a two-hour trip down memory lane."
