Ask your book anything except how it ends

Close Reader is an e-book reader for iPhone, iPad and Android. Select a word and a card translates it in context, reminds you who a character is or explains the hard part. The AI knows the book only up to your page.

Tap the underlined words in the book.

EPUB, FB2, MOBI, AZW3, PDF and TXT. Your own OPDS library. No sign-up required.

En un lugar de la Mancha, de cuyo nombre no quiero acordarme, no ha mucho tiempo que vivía un de los de , adarga antigua, rocín flaco y galgo corredor. Una olla de algo más vaca que carnero, salpicón las más noches, los sábados, lentejas los viernes, algún palomino de añadidura los domingos, consumían las tres partes de su hacienda. El resto della concluían sayo de velarte, calzas de velludo para las fiestas, con sus pantuflos de lo mesmo, y los días de entresemana se honraba con su vellorí de lo más fino.

Tenía en su casa una ama que pasaba de los cuarenta, y una sobrina que no llegaba a los veinte, y un mozo de campo y plaza, que así ensillaba el rocín como tomaba la podadera.

I don’t read past your page. Honest.

Help right where you stumble

Hold a word or select a passage, and a card brings what you need: a translation, a reminder about a character or the background. No switching to a dictionary or a search engine.

Words in context

The meaning in this very sentence, not a dictionary entry three screens long — or a plain definition when the book is in your own language. One tap translates the whole sentence or paragraph, and “Save word” keeps the word with the sentence where you met it.

TranslationWho’s this?Explain
sensible · [senˈsiβle] · adj. sensitive also: noticeable, perceptible False friend: it doesn’t mean “sensible”. Save word Whole sentenceWhole paragraph

“Who’s this?”

Forgot who Wickham is? Select the name, and the card opens on “Who’s this?” by itself. The answer comes only from the chapters you’ve already read. Under it, “First appearance” takes you to where the name first came up.

TranslationWho’s this?Explain
No spoilersWhole book

An officer in the regiment quartered at Meryton; Elizabeth meets him in chapter 15. He has told her that Mr. Darcy denied him the living he was promised — and she believes him.

Explain

Period details, allusions, idioms and tangled syntax, explained in plain words and in your language. “Check sources” looks it up on the web and links to the pages it used.

TranslationWho’s this?Explain

Entail: Longbourn can only pass to a male heir. The Bennets have five daughters, so the estate will go to a distant cousin — Mr. Collins.

Magic Touch

You decide what starts when you select text: a translation, an explanation or nothing at all. The switch is always at hand, in the reader’s top bar.

What starts by itself when you select text

The AI knows the book only up to your page

Scroll the page: the line follows you, and the answer grows with what you’ve read. Whatever is below the line never reaches the AI.

Scroll the page: the line follows you, and the answer grows with what you’ve read. Whatever is below the line never reaches the AI.

Who has taken Netherfield?

Not known yet. Mrs. Bennet is only about to tell. [1]

A young man of large fortune from the north of England. No name yet. [1]

Mr. Bingley, young and rich, from the north of England. [1]

Mr. Bingley: young, single, four or five thousand a year. [1]

Mr. Bingley: young, single, rich. Mrs. Bennet already sees him married to one of her daughters. [1]

How does it all end? I haven’t read past the line.

The boundary is the last line on your screen

It moves with you, page by page.

The AI isn’t told which book it is

In “No spoilers” mode the chat and “Who’s this?” get neither the title nor the author, so the AI can’t fill in the plot from memory.

The web is searched without your book

When a question needs facts from outside the book, the search isn’t told the title or the author, and spoiler sites are left out.

“Whole book” only when you choose it

Finished it, or reading it again? Switch modes and ask anything.

Ask anything about the book

A recap of what you’ve read, who’s who, why a character did what they did, what a scene means. Answers link to the passages they rely on — and the chat doesn’t look past your page either.

Several chats per book

Each one starts from its own question. “Discuss in chat” under an explanation opens a chat about that passage.

“Detailed answer”

When a short answer isn’t enough, it goes deeper and builds on what was already said.

The price before you ask

The field shows what a question costs, and every answer shows what it spent.

Quick questions

  • What happened so far
  • Chapter recap
  • Who’s who
  • Timeline
  • Main ideas

Questions beyond the book

Real history, science, the author’s life: when a question needs it, the chat looks things up on the web and lists its sources. You can turn this off in Settings → Privacy.

Recaps when you need them

Back to a book after a month? Close Reader offers a recap: the story in brief first, then the latest chapters in more detail. In the contents, every chapter you’ve read has its recap, and the one you’re in has a “Recap so far”.

“Where did they talk about that?”

Ask where something happened and the answer comes as a list of places: one card per scene, with the chapter’s name. A tap opens the book right there.

Bring your own library

And everything a good reader needs

Even without any AI, Close Reader is simply a good reader. It adapts to your eyes and remembers what you’ve read.

“I see no occasion for that. You and the girls may go, or you may send them by themselves, which perhaps will be still better, for as you are as handsome as any of them, Mr. Bingley might like you the best of the party.”

A map of the book

The slider shows chapters, bookmarks, notes and recent jumps. Drag it and you see the text at that spot. A jump only looks: your reading position stays put until you read three pages there or press “Read from here”. Your last jumps wait in “Where you’ve been”.

Words and thoughts stay with you

What you find in a book stays with you: words in your vocabulary, thoughts in your notes, good AI answers right beside the text.

Vocabulary with flashcards

Every word is saved with its translation and the sentence where you met it. Flashcards adapt to your memory, a daily reminder tells you when words are due, and the list exports to CSV.

Questions

Where can I get it?

In the App Store for iPhone and iPad and on Google Play for Android phones and tablets. It’s free to download.

How much does it cost?

You can try Close Reader for free: your first 7 days come with 1,500 energy (), no account needed. A word costs 1 ; bigger requests, like a chat question or a chapter recap, show their price before you ask. Reading, notes and flashcards stay free after that; AI help then needs a plan or energy you buy. Every feature is on every plan; plans differ in energy. Light (understand every word), Medium (never lose the thread) and Max (read between the lines) give 15,000, 40,000 and 80,000 a month: everyday translations, explanations and questions, plus about 25, 70 or 150 detailed answers. On a plan, a single answer costs no more than 500 . Medium starts with a 7-day free trial, and extra energy you buy never expires.

Which books can I read?

Your own EPUB, FB2, MOBI, AZW3, PDF and TXT files without DRM. The book can be in any language.

How do I translate an EPUB book on iPhone?

Open the EPUB in Close Reader: in the Library tap “+”, then “File on this device”, or pick Close Reader under “Open in…” in Files or Mail. Hold a word, and a card translates it as it is used in that sentence; “Whole sentence” and “Whole paragraph” translate more. The book stays in its own language: Close Reader translates what you select and doesn’t make a translated file. It works the same on iPad and Android, and in PDF, FB2 and MOBI books. How to translate a book, step by step.

Can I read a book in English and translate by tap?

Yes. Hold an English word, and its translation in that sentence appears over the page, in the language set in Settings → “Translate into”. “Save word” keeps it for flashcards. No book yet? Here are twelve free classics in English, from everyday words to harder ones.

Can I download books from my own library server?

Yes. Add your own OPDS catalog, such as a Calibre, Calibre-Web, Kavita or Komga server, then search it, filter and download books in one tap. Close Reader connects straight to your server. How to connect it.

What does the AI see of my book?

Only the text up to where you are — unless you switch to “Whole book” yourself. In “No spoilers” mode the chat and “Who’s this?” don’t even get the book’s title or author; explanations do. Details are in the Privacy Policy.

Can it answer questions beyond the book?

Yes. When a chat question needs facts from outside the book — real history, science, the author’s life — Close Reader looks them up on the web and lists its sources; under an explanation, “Check sources” does the same. In “No spoilers” mode the search isn’t told the title or the author. Such answers cost more: “Check sources” shows its price on the button, and the chat shows the most a search can cost while it runs. You can turn web search off in Settings → Privacy.

Where are my books stored?

On your device. If you sign in, the files sync through private storage that only your account can access. You can delete your account and all cloud data in Settings.

Do I need an internet connection?

Not for reading. Yes for translations, explanations and chat.
