Lecture notes
Students
Too lazy to read the lecture? Photograph it and listen on the bus, at the gym, or with the lights off.
More for studentsPhotograph any page. Hear it read aloud.
Learning a language? Photograph a page, open a PDF or paste text, and Outloud Reader reads it aloud in a natural voice, lighting up each phrase as it’s spoken. It can translate the text into that language first.

Biology 101, lecture 7
Photosynthesis, 14 Oct
Light reactions happen in the thylakoid membranes. Water is split, oxygen is released.
ATP and NADPH carry the energy on to the Calvin cycle, in the stroma.
CO₂ + H₂O + light → glucose + O₂
Exam: know both stages and where each one happens!

Liebe Anna,
Berlin, im März
vielen Dank für deinen langen Brief! Ich habe mich sehr darüber gefreut.
Hier ist der Frühling endlich da. Am Sonntag waren wir am See und haben zum ersten Mal draußen gegessen.
Kommst du im Sommer zu uns? Wir haben jetzt ein Gästezimmer.
Herzliche Grüße,
deine Marie -

Handout 3: The Industrial Revolution
Britain, about 1760–1840
- Steam power moved work from homes into factories.
- Canals, then railways, made goods cheaper to move.
- Towns grew quickly, and so did child labour.
Question for Thursday: who gained most, and who paid for it?
What is Outloud Reader?
Outloud Reader is a mobile app that reads text aloud in a natural voice. Photograph a page of a book, your notes or a handout, open a PDF, paste text, or ask AI for a text at your level, and the app turns it into audio, highlighting each phrase as it’s spoken. Choose the page’s own language to hear it as printed, or the language you’re learning to have it translated first.
It reads in 14 languages. Every book stays in your library with its audio, and playing it again is free. Outloud Reader works on iOS and Android, with no sign-up.
It’s free to download. Your first pages are free. More pages come in packs that never expire, or with a Premium subscription. There are no ads.
The phrase you hear is the phrase you see.
Press play and the voice starts reading. The phrase being spoken is highlighted, its sentence is set in black, and the rest of the page waits in grey, so you never lose your place.
Anna reached the platform at two minutes to midnight. The last train was already waiting, its doors open. She found a seat by the window, took out her notes and pressed play. Somewhere after the second stop, the lecture stopped feeling long.
Not an e-book store.
Your own text, out loud.
There’s no catalogue to browse. Outloud Reader reads what you bring it: the page in front of you, a PDF, a text you copied, or a text written for you.
-
Bring the text
Photograph pages one after another, pick photos from your gallery, choose pages from a PDF, paste text, or ask for a new one.
-
It becomes an audio book
The text is recognised from your photos and voiced by a natural voice. Pick a language other than the page’s and it’s translated first; anything already in that language is kept as it is.
-
Listen and follow
Press play. The phrase being spoken is highlighted and the sentence around it is set in black, so your eyes and ears stay on the same words.
For anyone who’d rather listen.
Four kinds of people use it most. You’re probably one of them.
Spanish, B1
Language learners
Translate any page into the language you’re learning, or ask for a short story at your level, A1 to C2, then read along with the audio to practise your listening.
More for language learnersLong reads
People who prefer to listen
Tired eyes, a long commute, dyslexia: let the text come to you by ear, and use large type and high contrast when you do look.

Dyslexia and reading difficulties
Hear the page while each phrase lights up, and follow at your own pace. Many people find a text easier to follow that way.
More on reading supportToo lazy to read the lecture? Listen to it.
Photograph your notes or the handout after class. By the time you’re on the bus, it’s an audio book you can play from your pocket.
- Up to 50 photos in one book, or just the pages you need from a PDF.
- Speed it up to 1.25×, or slow it down to 0.5× for the hard parts.
- Repeat each sentence up to five times before an exam.
- Hide the text, listen, and hold to check yourself.

Five ways to start a book.

Camera
Photograph page after page. The app finds the page in each photo and crops it; you can adjust the frame or use the photo as it is.

AI Text
Nothing to read? Describe what you want, or tap Surprise me, and a new text is written at your level, like a graded reader made for you. More on that below.
How AI texts work
Built for listening,
down to the phrase.
Every phrase, in sync
The phrase being spoken sits on a highlight, its sentence is set in black, and the rest of the page waits in grey.
Three ways to read
Follow the highlight, follow with your own eyes, or hide the text, listen, and hold to check a line.
Translated when you want it
Pick a language other than the page’s and it’s translated in natural sentences before it’s read. Pick the page’s own and it’s read as printed.
14 languages, natural voices
A woman’s or a man’s voice in every language except French, which has a woman’s. Switch in a book; both voices stay with it.
Your pace
Any speed from 0.5× to 1.25×, and each sentence repeated up to five times.
Easy on the eyes
Light, sepia or dark, with contrast, text size and line spacing to suit you.

Your library, kept safe
On iPhone and iPad, books and their audio are kept in your iCloud; on Android, the library stays on your phone, backed up by Google. Search the library by any word inside, and switch the app’s language without touching your phone’s settings.
Nothing to read?
Ask for a text.
Describe a topic — a dialogue in a café, a short mystery story — or tap Surprise me and the app chooses the topic and the kind of text: a story, a dialogue, a letter, a diary or an article.

Questions, answered.
Something else? Write to support@outloudreader.app and a person will answer.
Is this an e-book reader?
No. There’s no store and no catalogue. Outloud Reader turns the text you bring into audio: photos of pages, PDFs, text you paste, or a text written for you by AI.
Can it just read the page, without translating?
Yes. Choose the language the page is written in and it’s read as it is. Choose another one and it’s translated first.
Which languages can it read in?
English (US and UK), Spanish, French, Italian, Portuguese, German, Dutch, Polish, Ukrainian, Russian, Turkish, Japanese, Korean and Chinese — with a woman’s or a man’s voice in all of them except French, which has a woman’s voice.
Can I use it to practise listening in English or another language?
Yes. Photograph or paste a page in the language you’re learning and listen while each phrase is highlighted. Slow it down to 0.5×, repeat a sentence up to five times, or hide the text and listen first.
Can it read a PDF aloud?
Yes. Open a PDF, choose the pages you want, and crop away headers, footers and page numbers. Up to 50 pages go into one book.
Can it write texts at my level?
Yes. Describe a topic or tap Surprise me, choose A1–A2, B1–B2 or C1–C2 and a length of one to three pages. Writing is free; pages are used only when you make the text into a book.
Is it a text to speech app?
It turns text from photos, PDFs and pasted text into natural speech in 14 languages, but it’s made for listening and following along: each phrase is highlighted, and the text can be translated first. The audio stays in your library in the app; it isn’t exported as an MP3 file.
What happens to my photos?
To recognise, translate and read your pages, the app sends the photos and text you add to our server, where AI and speech services process them. Photos are deleted after processing, and your data is never sold or used for ads. The details are in the privacy policy.
Do I need an internet connection?
To create a book, yes: the text is recognised, translated and voiced online. The audio is then kept on your device.
Does it work on a tablet?
Yes, on iPad and on Android tablets. On iPhone and iPad, turn on iCloud sync and your books and their audio appear on every iPhone and iPad signed in to the same iCloud account. On Android, they stay on the device they were made on.
What won’t the AI write?
AI texts are written for a 13+ audience. Sexual content, graphic violence, hate and dangerous instructions are refused, among other things; the full list is in the content rules.
