Engine 01 · The Editor

Truth, written.

The writing surface your thinking actually deserves.

Codex is a sovereign Markdown editor engineered to Ulysses-grade standards — live rendering, zero chrome, typography you can feel. Press ⌘J and Synapse appears inline: eight AI actions — crystallize, refine, expand, translate, boardroom, summarize, extract, delegate — operating directly on your selection, never breaking your writing state.

When the work is done, export to eight editorial-grade templates — from Brutalist luxury to Chinese business standard (GB/T 9704). PDF. DOCX. Print-ready. This is not a note-taking app with AI glued on. This is an editor where writing and intelligence share the same surface.
