The margin is yours.

Why “Postille”
Post illa verba: “after these words”.The Latin origin of the word postil

In medieval manuscripts the text sat in the middle of the page. Everything around it stayed blank, and readers filled it in: a correction, a doubt, a “remember this”. They called them postils, because they came after those words.

The text belonged to someone else. The margin belonged to the reader. And centuries later, the margin is often the liveliest part of the book: it's where you can see a person thinking.

We still read that way today, but the margin ends up scattered: a sticky note, a photo of a page, a note in an app you can never find again. Meanwhile, reading apps mostly ask for a rating and a ranking.

Postille was made to put the margin back at the centre. A place where your notes are tidy, yours, and private — and where, when you decide, your shelf becomes a way to meet other readers.

Six chapters to read better.

Like a book: start from the chapter that makes you most curious.

IChapter I

Write in the margin

Every idea, quote and reflection stays attached to the book that sparked it. Find them again by book, by type or with search. They are yours and they stay private: they never become public unless you choose to share a quote.

  • Ideas, summaries, quotes and reflections
  • With page and chapter, always in order
  • Private for good, even with a public library
IIChapter II

A library your way

Add a book by title, ISBN or with the camera, and pick right away whether it is to read, being read or already read. Rate it in quarter stars: 3.75 is a real rating. Your library is private by default: you open it to others when, and if, you like.

  • Italian and international catalogues
  • To read · Reading · Read, in one tap
  • Quarter-star ratings and reviews
IIIChapter III

Milestones you earn

The first book, the first ten, the first thousand pages, several books in a month, days of reading in a row. 68 medals from bronze to legendary: no rankings, no comparing, just your own pace.

  • 68 milestones in 14 families
  • A small celebration when you earn one
  • No race against anyone
IVChapter IV

Read in good company

Follow the readers you trust and see what they are reading. Create lists to share with a link, open your profile with a public library, and get a notification only when it matters. If someone bothers you, block them in one tap.

  • The feed of readers you follow
  • Lists you can share with a link
  • Report and block in one tap
VChapter V

Your next book is right here

Browse the catalogue by genre, see what others are reading and get recommendations built on your taste: the genres you love, the authors you rated well, readers with similar taste. No ads, and no algorithm pushing what suits somebody else.

FAQ

Frequently asked questions

Who can see my library?

Only you, until you make it public in Settings. Even then, other readers see books, ratings and reviews: never your notes.

Does it work offline?

Yes. After your first sign-in you can browse and edit your library and notes offline; changes sync once you're back online. Social features (feed, discovery, profiles) need a connection.

Who can see my notes?

Only you. Notes are never public. You can choose to share a single quote — until you do, it stays private.

Can I bring my Goodreads or Anobii books?

Yes, by importing the CSV you export from their site. Ratings, reading dates, shelves and reviews are carried over where possible.

How much does it cost?

Using Postille is free. Some store links may carry an affiliate code that supports the project at no cost to you — it's always disclosed.

Is it an app I need to install?

You can open it in your browser or add it to your phone's Home screen: it behaves like an app, even offline. iPhone and Android versions are on the way.
