Per-document reading position
Every PDF you open gets its own saved page and scroll position. Close the tab, restart the browser, come back tomorrow — you land on the same paragraph, with the same theme, at the same text size.
A small reading progress bar
A subtle progress percentage shows how far you are into the document. It's surprisingly motivating for long reads, and it makes long textbooks feel less infinite.
A library you actually control
Files you read appear in a small private library on the home page, sorted by most recently opened. One click reopens the document right where you stopped. The library lives in your browser's storage on this device — no cloud, no account.
Bookmarks for the chapters that matter
Drop a bookmark on the page you want to return to (a key argument, a formula, a chart). They live alongside your highlights and notes, and they ride along when you export a backup.
Move your reading between devices
PDFcove doesn't sync automatically, on purpose — that would mean a server holding your files and your progress. Instead, exporting a backup gives you a single portable file: take it to another browser, restore, and your library, positions, and notes are all there.
It just works on phones too
Install PDFcove from your browser as an app and the same library and reading positions are available offline. Read a chapter on the train, finish it on a laptop later — same file, same place.
