Graphē One Codex
Core, Reference, and Professional
Choose the level of Codex that fits your reading practice. Codex is designed as a high-trust reading environment for complex texts. Begin with a serious core reader, move into deeper reference and annotation tools when needed, and scale into advanced professional workflows over time.
A focused reading environment for EPUBs, PDFs, and structured texts.
Codex Core is intended to feel complete: a serious everyday reader for long-form and structured works.
Deeper reference, annotation, and study tools for readers working across complex texts.
Especially useful for readers working with reference texts, legal material, technical documents, long-form scholarly works, richly structured documents, and exegesis.
Advanced research and professional reading workflows for large, demanding document collections.
Codex Professional is in active development. Register interest to receive updates on progress, availability, and professional or institutional access.
Core for serious reading. Reference for deeper study, annotation, and linked reading. Professional for intensive research and large-document work.
Codex may be introduced incrementally. The initial release may begin with Codex Core and Codex Reference, with Codex Professional developing later as a broader research and institutional layer.
Codex Core should feel complete. Codex Reference should deepen study and reference work without narrowing the app's identity. Codex Professional should extend the same reading environment into a full research workspace for large, structured collections.
