We don’t read to finish books. We read to become who we are.

Librum is your smart library: AI-crafted reading guides by author and series, a copilot that talks about your book without spoilers, and an app that tells you what to read next —and why. Plus a daily streak, your own library, stats that tell your story as a reader, and a library mouse that reads alongside you.

Coming soon iPhone · very soonApp Store Android · on the wayGoogle Play

iPhone first, then Android. In the meantime, the full app works from your browser. In English and Spanish.

Features

All your worlds at a glance

Every detail is designed for focus, clarity and transformation.

AI-crafted guides

Book-by-book paths by author and series: reading order, difficulty, golden rules and character maps. Your author isn’t there? Request their guide and we’ll let you know when it’s ready.

A spoiler-free copilot

Talk about the book you’re reading: characters, plot, where you left off. It only knows up to your exact page, so it never gives anything away.

Daily streak

Log your pages every day, protect your streak with reminders and watch your calendar come alive. And every year you keep reading gets its own celebration.

Reading timer

Time your session full screen, set a goal in minutes and, when you’re done, say what page you’re on: what you read today counts toward your streak, and if you’re just fixing your place, it doesn’t count as reading.

My Library

Add any book by hand, by ISBN or by scanning its barcode; sort it into your own sections with drag and drop, and import your whole collection from a CSV file.

Rereads

Read a book as many times as you like, and each read counts in its own year. A reread starts at page 0 without touching your streak. Print, digital or audio: audiobook minutes keep your streak alive too.

What to read next

The app tells you what to open and why: the next book in the series you left halfway, and whatever fits what you’ve already rated ★4–5. No questions asked.

🎲 The Reader’s Roulette

For when the problem isn’t what to read, it’s choosing: pick up to eight books, spin, and let chance decide. The winner comes with its reason.

Reading notes

Jot things down as you read, anchored to the exact spot you were at. Quotes, tags, hidden spoilers, all searchable. Always private, and exportable to Markdown.

Stats and calendar

Your pace, your authors and how you’ve grown: day by day on the calendar and year by year in your Librum Wrapped.

Goals, challenges and achievements

Set a pages or books goal, join community challenges and unlock 61 achievements across 12 families: streaks, pages, marathons, doorstoppers, notes, worlds, community and more.

Friends and community

Add friends, see what they finished and how many stars they gave it, read other readers’ reviews and climb the leaderboard. Your profile stays private until you say otherwise.

Reading duels

Challenge a friend to a week of pages, or set up a group duel with 3 to 10 friends: by pages or by minutes, from 3 to 30 days, with a live ranking and a podium at the end.

Partner streaks

Make a reading pact with your partner, your family or your best friend, 2 to 5 people. The pact’s streak belongs to everyone, and if someone missed a day, another member can cover it with one of their shields. Your personal streak stays untouched.

ABC challenge and bingos

One book for every letter of the alphabet, A to Z, filled in automatically with what you finish. Play solo or with friends, and when you complete it, share it as an image. And if you’d rather tick boxes, there are reading bingos too.

Book clubs

Start the club, then decide what to read: by vote, by roulette or by points —everyone nominates and hands out their points, and the result can be a plan for several months. Dates, everyone’s progress and a conversation that never lets a spoiler through past the page each reader is on.

Authors on Librum

Authors have a public page they can claim: a journal, answers to their readers’ questions, events with RSVP and an official club. Follow your favorites and get the news in your notifications.

Eleven themes

The app dresses up as the world you’re reading: Librum, Ivory, Romantasy, Fantasy, Sci-fi, Horror, Mystery, Historical and Manga, plus Halloween and Christmas, which come alive for their season. Each with its own palette and illustrated background, and it follows you to all your devices.

In English and Spanish

The whole app, in your language. The catalog too: titles and blurbs from each book’s English editions, all 75 series under their official names, and all 111 reading guides translated.

Always with you

Install it from your browser, and very soon from the App Store and Google Play. Synced to the cloud: keep reading offline and everything saves when you’re back.

Your reading buddy

A library mouse that reads with you

Adopt him, give him a name and feed him the pages you log. He lives in the app, floats on every screen and his mood follows your reading. He never dies and never gets mad: the streak is strict enough already.

  • He celebrates your milestones: a goal reached, a book finished, your streak
  • He reads by your side while the timer runs
  • He sits at the club table with everyone else’s mice, and shows up on your friends’ profiles
  • He dresses to match your theme, and stars in the cards you share
  • He yawns at night, stretches in the morning and chats about your day
  • Tap him and he opens the AI: the copilot, the summary up to your chapter and “What should I read?”
  • When you read, he sets off on a trip and comes back with sticker packs for your album

The Librum Album

Every time you read, your mouse puts on his traveler’s outfit, sets off on a trip and comes back with a pack of stickers from the genre you’re reading. Nothing to buy, nothing to lose: the album fills up with your reading alone.

  • 14 albums of 20 stickers: fantasy, horror, romantasy, mystery, sci-fi and more, with commons, rares and one shiny
  • 50 pages or 30 minutes of reading: the mouse heads out and soon comes back with your pack
  • Trade in duplicates for the ones you’re missing, or swap them with your friends
  • Albums you earn on your own: the mouse’s postcards, your reading nooks and your reading moments
The Librum difference

Reading guides crafted with AI

Pick an author or a series from the catalog and step into a complete reading path. Yours isn’t there? Request it: Librum builds the guide with AI on top of real bibliographic sources, reviews it, lets you know when it’s ready, and it’s then available to the whole community.

  • Recommended reading order, book by book
  • Difficulty level and golden rules so you never get lost
  • Anchor characters, connections and a map of the universe
  • From the author to each of their series, and back
  • A book you’ve read counts in every guide it appears in
  • Every guide, in English too

A copilot that never ruins the book

Librum knows exactly where you are and never crosses that line. Ask anything about the book in your hands: who that character was, what happened before, why that scene matters.

  • Chat about your book, limited to your exact progress
  • A summary up to your chapter, so you can pick it back up without rereading
  • “Something short that’ll make me cry”: recommendations on a whim
  • Once you finish, the line disappears and you can talk about everything
  • Before you use it, it asks for permission and tells you what gets sent. Don’t want it? Turn it off and it disappears from the whole app

🎲 The Reader’s Roulette

Sometimes the problem isn’t not knowing what to read: it’s not being able to choose. Pick up to eight books that tempt you, tap Spin and let chance choose for you.

  • Build the deck from your suggestions or from your unread books
  • Don’t own the book? It’s looked up online and goes straight into the deck
  • Saved to the cloud: build it on your phone, spin it on your laptop
  • The winner comes with its reason and never repeats the last one

Frequently asked questions

Everything you want to know

What is Librum?

Librum is a smart library for readers: AI-crafted, book-by-book reading guides by author and series, a copilot that talks about the book you’re reading without revealing spoilers, a daily streak of pages read, a personal library where you organize any book (which you can import from a CSV file), goals, challenges, friends, stats and an achievement system that tells your story as a reader.

What is Librum’s mouse?

He’s the app’s mascot: a library mouse you adopt and name. He feeds on the pages you log and his mood follows your reading: if you read today he’s happy and reading, if you read yesterday he’s waiting for you, and after two days without reading he falls asleep. He never dies and never gets mad. He celebrates your goals and finished books, reads with you during the timer, sits at your clubs’ table, shows up on your friends’ profiles and dresses to match your theme. Not your thing? Hide him from your account settings.

What is the Librum Album?

It’s a sticker collection that fills up as you read. Every 50 pages or 30 minutes of reading, your mouse sets off on a trip and comes back with a pack of stickers from the genre you’re reading. There are 14 albums of 20 stickers, with commons, rares and one shiny; duplicates can be traded in or swapped with friends. Nothing to buy: it’s free and fills up with your reading alone.

What is Librum Daily?

It’s a daily puzzle: guess the book of the day from its pixelated cover. You get six tries; with every miss the cover sharpens and a new clue appears, like the genre, the page count, the series or the author’s initial. Everyone plays the same book, and you can share your result without revealing the answer.

What are AI-crafted reading guides?

They’re book-by-book reading paths by author and series that Librum builds with AI on top of real bibliographic sources: a recommended reading order, difficulty level, golden rules, anchor characters and a map of the universe. You can turn on a guide from the catalog or request one for an author or series that isn’t there yet: we curate it and let you know when it’s ready.

Can the reading copilot spoil the book?

No. The copilot only knows the book up to your exact progress: if you ask about something that happens later, it kindly declines. The same goes for the chapter summary, which only covers up to the chapter you’re on. Once you finish the book, the line disappears and you can talk about everything.

Does Librum recommend what to read?

Yes. Ask for whatever you’re in the mood for in plain words —“something short that’ll make me cry”— and Librum suggests 4 to 6 books based on your real taste (genres, authors, favorites) and your moment, without repeating what you’ve already read and without spoilers.

I don’t know what to read. Can Librum help me choose?

Yes, and without asking you anything. “What to read next” suggests what to open and writes down the reason on every row: the next book in a series you left halfway, your unread books ranked by how well they match what you rated ★4–5, and, separately, the books you still need to get. It never offers a book out of its series order, and a suggestion you don’t want is dismissed for good.

What is the Reader’s Roulette?

It’s for when the problem isn’t not knowing what to read, but not being able to choose. You pick up to eight books that tempt you, tap Spin and chance decides for you. The deck is built from your suggestions or your unread books, and if you don’t own a book it’s looked up online and added. It’s saved to the cloud: build it on your phone and spin it on your computer. The winner comes with its reason and the right next step, and a new spin never repeats the previous winner.

Can I take notes on what I read?

Yes. As many notes per book as you want, each anchored to the exact spot you were at —including quotes and per-chapter notes for audiobooks. They take tags, can be pinned and marked as spoilers, work offline and are searchable from the “My notes” screen. They’re always private and you can export them to Markdown.

Can I log a book I’m rereading?

Yes. Every read of a book has its own dates and format (print, digital, audio or tandem), and it counts in its own year: in your year in review, your goals and your challenges. A reread starts at page 0 without erasing the days you already logged, so your streak stays intact. And if you opened it by mistake today, it undoes itself without touching your streak.

How do I get into Librum?

From your browser, at librumapp.com/app, and you can install it on your phone or computer like an app. Very soon from the App Store and Google Play too. Beta accounts carry the ✦ Librum Pillar badge next to their name, for good.

Is Librum available in English?

Yes. The app follows your phone or browser language, and you can set it in your account. In English the whole interface changes and so does the catalog: titles and blurbs come from each book’s English editions, series carry their official names and the reading guides are translated. Your progress doesn’t move when you switch languages.

Can I import my library from a CSV file?

Yes. Librum’s My Library lets you add any book by hand, by searching its title or ISBN or by scanning its barcode; organize it into your own sections with drag and drop; and import your whole collection from a CSV file.

Can I read with my friends?

Yes. You can find other readers, send friend requests, see what they finished and how many stars they gave it, compete on the friends leaderboard, challenge them to a reading duel —one on one or in a group of up to 10— and read reviews from the community. Your profile is private by default: you decide what to show.

Can I read in a group, like a book club?

Yes. Create a public or private club, invite people and pick the book by vote, with a roulette or by points: in a points vote each member nominates their books and hands out their points, and if you want, the result is a plan for several months, one book a month. Each read has its own dates and its own thread, and there a message marked past your page reaches you without its text: the spoiler brake is enforced by the server, not a visual effect you can get around.

I’m an author. Can I have my page on Librum?

Yes. Every author in the catalog has a public, indexable page, and they can claim it to post a journal, answer readers’ questions, announce events with RSVP, open an official club and link to where their books are sold. Librum doesn’t process payments: the links go wherever the author sells.

Does Librum work offline?

Yes. Librum is an installable PWA: you can keep logging your reading offline and everything syncs to the cloud as soon as you’re back online.

Is Librum on the App Store and Google Play?

Very soon. The native app launches on iPhone first and on Android after that. In the meantime, Librum works fully from your browser and installs like an app. Your account is the same everywhere.

How much does Librum cost?

Librum is free, with no time limit. Librum Codex adds more AI, every theme, advanced stats, unlimited clubs and scanner, among other things: US$3.99 a month or US$29.99 a year, and a one-time US$59.99 lifetime payment for the first 100. In your country it may show in your currency and, in some, at a lower price. Your streak, your library, joining clubs, exporting your data and your Wrapped are never charged. See pricing.
