What is the New Codex for Knowledge Work?

On June 2, 2026, OpenAI announced a major expansion of Codex, transforming it from a developer-only assistant into a comprehensive business AI tool for knowledge workers. This move comes as non-developers now make up 20% of Codex's 5 million weekly users, growing at 3x the rate of developers. [citation:1]

Key Features

1. Six Role-Based Plugins

OpenAI released specialized plugins for different knowledge work roles, each integrating relevant apps, skills, commands, and workflows: [citation:1]

  • Data Analytics: Connect to Snowflake, Databricks Genie, Hex, and Tableau
  • Creative Production: Integrate with Figma, Canva, Shutterstock, Picsart, and Fal
  • Sales
  • Product Design
  • Public Equity Investment
  • Investment Banking

Total: 62 integrated apps and 110 skills. OpenAI also previewed future plugins for Corporate Finance, Marketing Strategy, Private Equity Investment, Strategy Consulting, and Legal. [citation:1]

2. Sites – Collaborative Website Builder

Codex can now generate interactive websites from reports or documents, including dashboards, workspaces, KPI monitors, charts, and knowledge bases. [citation:1]

Users can share these sites via URL for team collaboration, making Codex competitive with AI app builders like Replit, Lovable, and Wix. [citation:1]

3. Annotations for All Document Types

Codex's annotation feature now supports documents, spreadsheets, and presentations — not just code. Users can circle any content and request modifications via natural language. [citation:1]

Availability

  • Plugins & Annotations: Generally available now [citation:1]
