Gather your life stories into a book.
Talk or type a memory, bring in what you've already written, and Building Blocks keeps track of the people, places and moments in it, so you can shape them into a book.
Private, and by invitation for now.
Chapter 3 · The lake
The summer of 1962, my father packed the five of us into the green Ford and drove all night to Flathead Lake. Nobody slept.

How it works
Tell it, or bring it in
Speak a story out loud or type it, or add what you already have: Word files, PDFs, plain text. One file or a whole folder.
Claude finds the pieces
Claude reads your writing and lists the people, places, objects, dates and themes, each pointing back to the exact words it came from.
Shape it into a book
Put events on a timeline, arrange them on a board, and gather passages into stories in the order you'd tell them.
Made for the way memories come back
Out of order, a piece at a time, and full of people. Building Blocks keeps track so you can keep writing.
Talk or type a story
Press Start talking and tell it the way you'd tell it at the table. Your words appear as you speak, to read over and fix before saving. Where a browser can't listen, type instead.
Bring in what you've written
Word, PDF, text and Markdown, several at a time or a whole folder. Your originals are kept exactly as they are.
Every person and place, kept straight
Each one gets a page: every name they went by, the events they're in, and every passage that mentions them.
Saved stories and story ideas
Gather passages into a story in the order you'd tell it, and see which threads in your writing could be stories of their own.
See it come together
Once Claude has read your writing, the pieces show up in views you can arrange.
- around 1958The move west
- 1962Summer at the lake
- the 1970sThe ranch years
- 1981Leaving home
A timeline that takes a rough date
Memories rarely come with exact dates. Put events in order on “around 1958” or “the 1970s,” and change them later.

A board to sort it into chapters
Drag events and your own notes into the chapters of your book, or use a menu on a phone.
A map of how it connects
See how a passage ties to the people, places and stories around it, and draw your own lines.
Give it a cover
Pick a painting from a library of public-domain art, add your title and name, and choose a layout. Seeing your book with a real cover makes it feel like a book, long before it's finished.

Your stories stay yours
Life stories are about real people. Building Blocks treats them that way.
- A book is seen only by the person who started it and the helpers they add.
- Nothing in a book is ever public, and there are no share links.
- When Claude reads your writing, it goes to Anthropic, the company that makes Claude, which doesn't train on it.
- Building Blocks helps you gather and track your story. What you publish, and how, stays your call.
