KODEKS: PDF Reader

Nexus Hive

About this app

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.

• Manuscript Mode
Transform compatible PDF text into a beautifully styled illuminated manuscript with parchment, decorative borders, drop caps, ornaments, and book-inspired layouts.

• Original PDF Mode
Switch back to the original PDF view whenever you need exact source fidelity.

• Offline OCR
Recognize text from scanned or image-based PDF pages directly on your device.

OCR resources for English and Turkish are included locally, so supported OCR tasks can work without uploading your documents to an external service.

• Scanned PDF Support
KODEKS can detect image-backed and scanned pages. When reliable text extraction is possible, recognized text can be used for manuscript reading. When it is not, the original page can be preserved as a facsimile.

• Local Document Processing
Your PDFs are processed on your device.

KODEKS does not require an account and does not upload your documents to our servers.

• Private by Design
No advertising SDKs.
No analytics SDKs.
No tracking.

• Portrait and Landscape Reading
Read one page at a time in portrait mode or enjoy a two-page codex-style spread in landscape.

• Decorative Reading Experience
Experience parchment textures, illuminated initials, floral borders, ornaments, historical-inspired page styling, and carefully preserved figures and document regions.

• Open PDFs from Android
Choose documents using Android's system file picker or open supported PDF files directly with KODEKS.

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.

READ DIFFERENTLY

KODEKS is designed for:

• books and ebooks in PDF format
• academic documents
• scanned documents
• historical texts
• lecture notes
• reports
• long-form reading
• readers who simply want a more atmospheric way to experience PDFs

Whether you want a normal PDF reader or a digital codex on your phone, KODEKS lets you choose how each document should be experienced.

Your documents stay yours.
