Foliant

Turn any PDF into a book you can actually study from.

Key capabilities

Foliant is an offline-first reader that turns a PDF into an interactive book. Read it in chapters, highlight in colour, switch to focus mode, and turn what you read into flashcards.

Chapter bookmarks

Jump between chapters and pick up exactly where you stopped.

Colour highlights

Mark what matters in the colours you choose and find it again later.

Focus reading mode

Remove everything except the page so long reads stay comfortable.

Flashcard generation

Turn passages into question and answer cards that reveal on tap.

Works offline

Your library lives on your device, so reading never depends on a connection.

Installable

Add it to your home screen as a Progressive Web App, or use the Android app.
