KODEKS is a private, offline-friendly PDF reader that transforms ordinary documents into an immersive illuminated manuscript reading experience.

Read PDFs in their original form, or switch to Manuscript Mode to reimagine compatible documents with parchment pages, decorative borders, illuminated initials, medieval-inspired typography, and a book-like reading layout.

KODEKS is built for readers who want more than a basic PDF viewer — without giving up the original document when accuracy matters.

KEY FEATURES

• PDF Reader
Open and read PDF documents directly from your device with a clean, focused reading experience.

BUILT FOR BOTH BEAUTY AND FIDELITY

KODEKS follows a simple principle:

Understand it → reflow it.
Don’t understand it → preserve it.

Text that can be interpreted safely may be reformatted into the manuscript experience, while complex or uncertain content can remain closer to the original source.

This helps KODEKS preserve important figures, scanned pages, tables, equations, images, and other document elements instead of forcing everything into a generic text layout.

KODEKS is designed for:

• books and ebooks in PDF format
• academic documents
