Every book and document, one library
Import EPUB, PDF, Markdown, text, HTML, FB2, DOCX and ODT. Grid or list, your own categories, rich covers, and a progress line under every book.
Three things, done well
Read. Understand. Listen.
Bring books and documents together in one comfortable reader, understand selected text with private on-device translation, and keep reading and understanding in one focused experience.
Long-press a word, translate on device
Pick a language pair, download its on-device model once, and translate selected passages without leaving the page. The result appears under the text; one tap saves the word.
Or just listen
Listen to books with Read Aloud as a Coral Pro member: skip by sentence or paragraph, set the speed and a sleep timer, and jump back to reading any time.
Made for comfort
Read exactly your way.
Light, sepia or dark. Fonts, size, zoom, margins, line height and letter spacing, each previewed live on the page you are reading. Right-to-left scripts flow naturally, page by page.
Scroll, Paged or Mixed
Read in one continuous scroll, turn discrete pages, or scroll to read and turn a page from the edge. Flip horizontally, vertically or both.
Type set your way
Bundled fonts for many scripts, font size and zoom, margins, line height, letter spacing, natural or justified text, brightness and rotation lock.
Chapters, bookmarks, search
Jump by chapter with page numbers, drop bookmarks as anchors to return to the exact page, and search inside the book.
Never lose your place
Every book remembers its position. A progress bar with chapter tooltips shows where you are, and Book info keeps chapter and percent at a glance.
Highlights & notes
Highlight in yellow, blue or pink, keep notes, and open footnotes in place.
Multi-language
Books in any script, right-to-left layouts and direction-aware controls, an app interface in your language, and translation between the languages you read. Reading stats and streaks keep every page counting.
Stay in the story
The word journey, inside the book.
Leaving a book to look up words breaks reading flow. Coral Reader turns reading moments into learning moments without leaving the page.
Long-press. Translate.
Understand selected text with private, on-device translation, in the language pair you choose, once its model is downloaded.

Private by default
Your books stay yours.
Your library lives on your device. Translation runs with downloaded on-device language models, so the passages you select are never sent to a translation service. Read Aloud uses on-device voices.
- No account. Import a book and start reading.
- Manage downloaded translation models inside the app; downloads over cellular are off by default.
- Machine translation is a comprehension aid, not a professional translation.
