For ChatGPT Desktop

Local UI + Local Runtime

Install CogentSpec on your own machine for local files, Git, terminal access, tools, optional local models, and a direct downloadable install path.

Best for local licence and support journeys, direct repository work, and keeping execution close to your environment with optional account connection.

For ChatGPT Web

Contract workspace + ChatGPT

Use CogentSpec Web as the persistent project workspace while ChatGPT remains the official, independent AI application.

Install Desktop Bridge once, then enter $cogentspec in the ChatGPT Project you want to connect. The command returns the matching web workspace without opening tabs or rearranging windows.

Explore the Web workflow

Choose the closest project type. CogentSpec will bind the standards, obligations, and release gates that apply to the build.

Engineered Contract Packs

Skip the setup. Start from a production system.

CogentSpec defines 34 engineered project-type contracts. Website v2.1.0 is the first fully executable Contract Pack, with additional packs being progressively activated.

34engineered project-type contracts

Website Contract Pack v2.1.0 contains

  • Starter application
  • General and showcase patterns
  • Pinned contract binding
  • Selected project profile
  • Semantic application shell
  • Responsive safeguards
  • Accessibility controls
  • Foundation test suite
  • SEO discovery routes
  • Acceptance evidence map
  • Local launch automation
  • Release recipes
  • Content release gate
  • Local, private, and public modes

A curated, opinionated production library with an AI operating layer

Repeatable work should not restart from zero.

Freelancers and agencies rebuild authentication, administration, security controls, test harnesses, and deployment configuration across the same categories of project. CogentSpec starts with those decisions engineered and the acceptance criteria already defined, turning time saved into something measurable rather than a vague claim about better guardrails.

Evidence, not assertion

Inspect the evidence that makes Website v2.1.0 release-ready.

These sanitised diagrams come directly from the current Website Contract Pack structure, acceptance map, foundation tests, and release checks. Protected contract rules remain server-side; the production evidence does not.

01

Generated architecture

What the pack instantiates

  1. Contract pin.coge/contract-binding.json
  2. Selected profile.coge/project-profile.json
  3. Website foundationapp/ + components + configuration
  4. Acceptance evidence.coge/acceptance-map.json
  5. Release recipe.coge/release-recipe.json

The contract version and checksum are pinned. A mismatched Contract Pack stops rather than presenting an incompatible build as compliant.

Verification architecture

What blocks an incomplete release

  1. Build and foundation testsDeterministic source, semantic structure, keyboard readiness, and rendered output.
  2. Accessibility and discoveryResponsive safeguards, focus visibility, reduced motion, robots, sitemap, and not-found recovery.
  3. Content release gateStarter content, missing assets, and unresolved decision markers block release.
  4. Controlled release modeLocal, private, or explicitly confirmed public deployment.

Architectural difference

Direct dialogue.Governed delivery.

CogentSpec keeps you in direct conversation with the AI while an approved project contract provides the structure, requirements, controls, and acceptance criteria alongside that conversation.

01

Agentic builders

The agent mediates the work.

Platforms such as Replit-style builders place an AI agent inside their own execution environment. The agent edits files, runs commands, maintains working state, and reports through the platform's agent loop.

02

CogentSpec

The contract governs the work.

You discuss refinements naturally with the AI rather than routing every change through a separate builder agent. The contract keeps delivery controlled without becoming a translation layer between you and the model.
