An open format for AI reasoning

.CORTIX.

A standardized semantic representation for AI reasoning over financial documents. Open spec, open validator, implementation-independent.

The number 23,300

One number. Three formats. Three levels of truth.

Markdown
| EBITDA | 23,300 | A string in a cell. No metadata alongside.
Not carried
  • What period?
  • What unit?
  • What page?
  • Actual or estimate?
  • How was it extracted?
  • Can you trust it?
"Readable. Not reasoning-ready."
JSON
{"ebitda": 23300} A number under a key. Context often externalized or inconsistently embedded.
In practice
  • Context fragmented
  • Schemas inconsistent across sources
  • Provenance rarely enforced
  • Deeply nested or inconsistent data degrades LLM reasoning
"Structured. Not standardized for reasoning."

Every number carries
  • What it measures
  • When it applies
  • Where it came from
  • How it was extracted
  • How much to trust it
  • Actual or estimate
"Structure and provenance, enforced."

Every fact in a .cortix file has a passport.

What's inside the portal

.CORTIX · the format

The open format every reasoning system would adopt.

The full spec, sample corpus, validator, and integration patterns. Plain text, implementation-independent, designed to be emitted and consumed by software that has nothing to do with Cortix.

  • Whitepaper · positioning and adoption paths
  • Specification · per-document and corpus-map grammars
  • Sample corpus · synthetic four-document deal
  • Validator · open source
  • FAQ · adoption mechanics, license, patent posture
  • License + non-assertion covenant — coming soon

Forge · the engine

One production-grade implementation.

Cortix Forge converts deal documents into .CORTIX files at production scale. Forge is a commercial product; the format is not coupled to it.

  • Product overview
  • Pricing tiers
  • Demo and sandbox access
  • Pilot architecture and integration patterns
  • Pilot agreement template — coming soon

Currently invitation-only.

The portal is gated during the controlled rollout to first-wave platform integrators. The spec, validator, and sample corpus open to the public when the license and non-assertion covenant publish.
