How it works

Three moves. That's the whole thing.

1
Leave a note
Mark your chapter and drop a reaction, a prediction, the line you can't get over. It anchors to that exact page.
2
It stays sealed
However far ahead you are, the people reading with you see nothing. No spoilers, ever. The system enforces it.
3
It opens when they arrive
The moment a friend reaches that page, your words are waiting. Reading together, even when you are apart.

Bring your club along

A room isn't just a book.
It's a group with a history.

Your book club doesn't end when the book does. Rooms link into a named reading group, so when you finish, one tap opens the next book together, carrying your people and every note you left behind.

Sarah opened the room. One tap and the whole club is in.

"Sarah's Book Club" isn't a room. It's a relationship, one that moves from book to book, carrying every reaction and every note along with it.

like you were there together.

Spoiler-proof is the promise. These are the touches that turn it into a place people actually gather.

Everyone has a color
Each reader gets their own. Their dots move through the book beside you, so you feel them there even before a note unlocks.

A book about time, not games. @David you'll see.

React, reply, and mention
Like a note, answer in a thread, tag a friend by name. A real social layer, and every reply stays sealed at its chapter too, so nothing leaks.

Notes that never expire
A note waits at its page however long it takes. Months later a new reader arrives, and it's still there for them.

The moment you want to share

You know the feeling.
The book that changed something.

Somewhere in every great book, a line lands and you have to put it down. You want to tell someone who will understand. But sharing that feeling has always been broken.

The group chat spoils it.
Someone hasn't reached that chapter. One message ruins it forever. So you say nothing.
Book club is weeks away.
By then the feeling has faded. The conversation about that exact scene never quite lands.
So the moment is lost.
The reaction that mattered vanishes. You close the book and it's gone.

What if that connection had a home? Not a chat. Not a spoiler. The exact feeling you had, waiting at the exact page, for the person who's ready to feel it too.

This is inkwool.

Beyond the moment

Other apps capture what you read.
inkwool captures when.

Not the summary. Not the review three weeks later. The reaction you had at the page where it happened. That is what inkwool keeps, and it holds across time, distance, and loss.

The same book, a year apart.
She read it last spring. You finished it fourteen months later. Her notes were still there, at every chapter that mattered. The window didn't close.
A note from someone who is gone.
Your father had something to say about every page. Those reactions lived only in his head. inkwool lets the people we lose leave something behind.
A book club across a lifetime.
Different cities, different schedules, the same book. The reactions don't wait for the monthly call. They arrive at the right page, exactly when they should.

"Some notes outlast the people who wrote them."

That is what we're building.

Who reads together

Anywhere people read
the same thing, together.

If two people are reading the same pages and one of them has something worth saying, inkwool is for them.

Book clubs
The meeting starts before the meeting.
Leaders set questions that unlock chapter by chapter. By the time you gather, the conversation is already alive, and it stays open long after the last page.
Families & friends apart
A parent and a grown child, different cities, same book.
Their notes find each other at every chapter that matters. No phone call, no waiting. Just the right words at the right page.
Reading solo
You don't need a partner to start. Just a book.
Leave notes and grades for yourself. Then, when a friend picks up something you've already read, your annotations are waiting for them. Your past reading becomes a gift.
Any book, any format
Kindle, Audible, Libby, or a paperback.
inkwool works around your reading life instead of asking you to change it. All it needs is a chapter or a percentage.

What a shared read feels like

The feeling we're after.

We're early, and building this with the readers joining now. Here is the feeling we design every detail toward.

"
You leave a note in chapter four.
Three weeks later your sister reaches it, and calls you. She says, "I know exactly what you meant." That is the whole point.
"
The group chat never spoiled it.
For once, everyone can talk about the book while they're still reading it, each at their own pace, nobody ruined for anyone.
"
Your shelf becomes a gift.
Every book you journal alone is a room someone can join later, your reactions waiting at every page you loved.
