New: Mirror-write mode for private invention logs
A codex for polymaths who paint, build, and think across disciplines
Codex is the studio platform for artists who are also inventors, naturalists, and engineers. Publish paintings beside diagrams, sketches beside specifications, and let your full practice live in one continuous notebook.

Everything you need to ship
One platform, every primitive. Replace a half-dozen tools and ship in an afternoon.
Folios And Quires
Organize work into bound folios that mix paintings, diagrams, notes, and observations. Each folio reads as a single body of thought, not a scattered grid.
Cross-Reference Engine
Link drawings to paintings, paintings to inventions, inventions to scholarly references. The codex builds a living graph of how your ideas connect.
Invention Patents
Document working prototypes, models, and inventions with versioned schematics. Mark which ideas are public, patented, or held private as workshop secrets.
Naturalist Field Notes
Tag works by botanical species, anatomical study, or geographic origin. Filter the entire codex by subject the way Linnaeus would filter a herbarium.
Mirror Writing
Keep private invention logs that even your collaborators can't read — encrypted at rest with a per-folio key only you control.
Commission Ledger
Track commissions from Sforza-sized institutions to single-portrait patrons. Milestones, deposits, and acceptance criteria flow through one transparent ledger.
Unified dashboard for everything you ship
Get a complete view of your business with real-time reporting, automated reconciliation, and actionable insights — all in one place.
