Read. Tap. Remember.

Learn a language from anything you read.

Turn any book, article, or PDF into a quiet language lesson. Tap a word for its meaning in context, save what's new, and let short daily reviews make it stick.

How it works

Three steps from reading to remembering.

  1. 01

    Bring your own text

    Add a book, paste an article, or open a PDF. Share to oqou from Safari, Files, or anywhere, and it's ready to read in seconds.

  2. 02

    Tap any word, stay in the flow

    One tap shows an instant, in-context meaning and translation right where you are. No pop-out dictionaries, no losing your place.

  3. 03

    Save it, then let it settle

    Keep new words and phrases with a tap. Smart Review brings them back at just the right moment, in sessions that take a few minutes.

Features

Import anything

If you can read it, you can learn from it.

Books, news articles, research PDFs, blog posts, your own documents. Bring them in by web link, file, or paste, and oqou keeps the formatting clean and readable, so it still feels like reading, not studying.

  • Import from the web, Files, or paste
  • EPUB, PDF, and plain text
  • Your library, organized and offline-ready

Tap to translate

Understand the word without leaving the sentence.

Tap once. oqou reads the surrounding sentence and gives you the meaning that actually fits, not a generic dictionary guess, layered right over the page. Tap again to save it, and keep reading.

  • In-context meaning, not a literal lookup
  • Works fully on-device, instantly
  • One more tap to save it for later

Smart Review

A few quiet minutes a day. A year of progress before you know it.

Saved words become your personal deck, and Smart Review uses spaced repetition to resurface each one right as you're about to forget. oqou marks the journey too, from your first month to your third to your first full year of reading.

  • Spaced repetition, tuned to you
  • Short daily sessions that take minutes, not hours
  • Quietly tracks your progress over time

Your shelf

Every text earns a cover worth opening.

A plain PDF is forgettable. So oqou gives every text you import a unique cover, generated right on your device, turning your imports into a bookshelf you're proud of and actually want to come back to.

  • A distinct cover for every import
  • Generated on-device, fast and private
  • No two covers look alike

Free level test

Know your level before you read a single page.

A quick, adaptive test places you somewhere between A1 and C1 in about two minutes, using a yes/no vocabulary staircase. Take the fuller version any time in Settings for a deeper placement, up to C2, and oqou starts you on stories written exactly for your level.

  • Free, in the app, no account needed
  • About 2 minutes for a first placement
  • A longer Settings test adds grammar and reading, up to C2

Stories, printedPro

Turn any story into a PDF worth keeping.

Export a story with a cover generated just for it, the text set in the reader's own serif type, and a vocabulary appendix built from the words you saved while reading, finished with a small oqou colophon page.

  • A unique cover for every export
  • Typeset for reading, on paper or on a tablet
  • A vocabulary appendix made from your saved words

Starter stories export free. Exporting your own imports is part of oqou Pro.

FAQ

Questions, answered.

Still curious? Email hello@oqou.app and we'll help.

Do I need oqou Pro to use it?

No. Importing texts, tap-to-translate, saving words, Smart Review, and generative covers all work for free and run on your device. Pro adds AI explanations and premium read-aloud voices only when you want them.

What can I import?

Books (EPUB), PDFs, web articles, and plain text you paste. Share to oqou from Safari, the Files app, or most apps with a share sheet, and it becomes a clean, readable page automatically.

Which languages does it support?

oqou works with the text you bring it across major world languages for reading and tap-translation. Your target language is simply whatever you choose to read.

Is my reading private?

Yes. Reading, saved words, and reviews stay on your device by default. Pro features that use AI (from OpenAI) only send data the moment you use them. Nothing is shared in the background, and nothing is sold. See our Privacy Policy.

Does it work on iPad?

Yes. oqou is a universal app for iPhone and iPad, and your library follows you across your devices.
