Margina - Read & Highlight

Margina is a calm, private home for everything you read.

Send yourself a PDF, EPUB, Word doc, Markdown file, or plain text. Margina opens them all in one distraction-free reader that remembers exactly where you left off. No account, no cloud requirement, no clutter: just you and the page.

A LIBRARY THAT LOOKS LIKE ONE
Your documents live on a clean shelf of covers, each showing its format and how far you have read. Prefer rows? Switch to list view with one tap. Filter by what you are reading now, what is new, and what you have finished, and pin the book you keep coming back to.

HIGHLIGHT AND ANNOTATE
Mark passages in five colors, attach a note in the margin, and drop bookmarks anywhere. Drag across a PDF page to select and highlight in one motion. Every annotation is gathered in one place, ready to browse, filter, and revisit. Tap any highlight to jump straight back to its page.

FIND ANYTHING, FAST
Search across titles, authors, highlights, and notes at once. Matches light up inside the results exactly like highlights on a page, grouped by document so you always know where a passage came from.

STAY ORGANIZED
Sort your library into color-coded folders for work, study, research, or that stack of essays you have been meaning to get to. Jump back into any book at the exact spot, or the exact highlight, you were last at.

MADE FOR LONG READING
A reading experience designed like a well-set book: quiet paper tones, generous margins, and your progress drawn as a thin rule in the margin itself. Choose paper, sepia, or dark. Tune font, size, line spacing, and margins right in the reader. Includes a dyslexia-friendly typeface option and respects your system accessibility settings, including font scaling, TalkBack, and reduced motion.

EVERY FORMAT YOU ACTUALLY USE
PDF reader, EPUB reader, Word document viewer, Markdown reader, and plain text notes, all in one app. Import from any app's share menu, your file manager, email attachments, or downloads. Everything works offline, on the train, on a plane, or at the cabin with no signal.

EXPORT AND SHARE
Turn your highlights and notes into a clean Markdown file or a formatted PDF and send them to your notes app, your research workflow, or a friend.

PRIVATE BY DESIGN
Your library lives on your device. No account, no sign-up, no tracking, nothing to set up. Margina hosts nothing about you. Reading is personal; your reading data should be too.

MARGINA PRO
Upgrade to back up your library to your OWN Google Drive, unlock the sepia reading theme, export your annotations, and add unlimited documents. Available monthly, annually, or as a one-time lifetime purchase. Your backup is stored in your Google Drive's private app folder, never on our servers, so even Pro keeps your data yours.

WHO MARGINA IS FOR
Students annotating readings and lecture notes. Researchers working through papers. Book club readers who argue in the margins. Writers collecting passages. Anyone who sends themselves things to read later and actually wants to read them, without ads, feeds, or noise.

BUILT FOR FOCUS
There is no feed to scroll, no streak to protect, and no notification begging you to come back. Margina does not want your attention; it wants to return it to you. Open a document, and the interface steps aside until you ask for it.

Read anything. Mark it up. Keep it yours.
