Every reader
has a pile
The book on the nightstand since March. The one you swore you’d finish. Books are easier to finish when someone is waiting for the next page.
Your pet knows what you’re reading
Tell it your book, and it talks about the book’s people and places while you read.
Gatsby keeps staring at a green light. I know that look.
And it changes with what you read
Read three gothic novels and it gets a little dramatic. Every book leaves a mark, so no two silverfish are alike.

Five eggs. One awake at a time.
Each creature has its own story and its own way of reading with you. When you want a change, the one awake goes to sleep. Nobody gets left behind.
The Silverfish
Lives between the pages of old books and eats them. Dry, a little cynical, and full of opinions about everything you read.
IT SAYS
“I ate well. I’ll be kind for about fifteen minutes.”
The Ash Cat
Comes from cats who pulled pages out of the ashes and learned them by heart. Watchful, loyal, a little paranoid. Keeps your pages instead of eating them.
IT SAYS
“I watch the door, you turn the page. Deal?”
More are on the way
Three eggs are still warming up. Each one has its own story, its own room and its own opinions about your books. They’ll hatch later, one at a time.

Questions before the egg hatches?
Still have a question?
The Silverfish readers hang out on our Discord, and so do we. Ask anything.
Ask on DiscordWhen does it come out?
There’s no date yet. Join the waitlist and you’ll hear first, and you can help test it before anyone else.
Does it work with any book?
Yes. Read e-books (EPUB) right in the app, in its own reader, or bring a paper book: add it by title or by scanning the barcode.
Will it spoil my book?
Never. It only talks about pages you’ve already read.
iPhone or Android?
We’re starting with iPhone. If you’re on Android, pick it on the form: it tells us how soon to build it.
What happens if I stop reading?
Nothing bad. It falls asleep in its room and wakes up when you open a book again.
Can I have more than one creature?
Yes. The Silverfish and the Ash Cat come first, and three more eggs hatch later. One is awake at a time, and switching puts the other one to sleep. Nobody gets left behind.
I already use Silverfish. What happens to it?
Nothing changes. The plugin stays free and keeps getting updates.
