OpenAI Launches Codex Plugin System, Integrating Slack, Figma and Other Tools for AI Agent Workflows

OpenAI initially positioned Codex as a software development agent but is now expanding it into a general-purpose knowledge-work platform for research, data analysis, reports and presentations. The company said on June 2, 2026, that Codex had more than 5 million weekly active users, an increase of more than sixfold since the desktop app launched in February. Non-engineers accounted for about 20% of users, and their ranks were growing more than three times as fast as those of developers.

OpenAI launched six plugins spanning 62 apps and 110 skills on June 2, 2026, and previewed Sites. On April 22, it unveiled a WebSocket mode for the Responses API that made agent workflows 40% faster. On April 2, it cut the annual ChatGPT Business price from $25 to $20 per seat. Eligible teams adding Codex seats could receive $100 in credits, capped at $500.

OpenAI’s Codex is an AI coding agent that can read and write code locally, run tests and create Git branches. The desktop app first launched on macOS on February 2, 2026, as a multi-agent “command center” where developers can assign tasks in parallel, review diffs and preserve project context across the CLI and IDE. Native Windows support is therefore important for broader enterprise adoption and security governance.

OpenAI launched the Codex app on Windows on March 4, 2026, supporting parallel work by multiple agents and using worktrees to isolate tasks within the same repository. Settings and history carry across the app, CLI and IDE. Details disclosed on May 13 showed that the native sandbox uses a dedicated account, restricted tokens and Windows Firewall controls to manage write and network access. OpenAI did not announce separate pricing.

OpenAI’s Codex is an AI agent that can write code, run tests and handle development tasks on a user’s behalf. Its expansion to the ChatGPT mobile app lets developers monitor work while away from their computers. GitHub’s Copilot App, meanwhile, strengthens parallel management of multiple agents and workflows, moving agentic development beyond the editor into a standalone desktop environment.

In July 2026, OpenAI began allowing users to connect remotely through the ChatGPT mobile app to Codex running on a Mac. Users can track progress, review output, approve actions and launch new tasks. During the same period, GitHub released a technical preview of the GitHub Copilot App, a desktop interface for centrally managing multiple workflows and agents. Neither company disclosed pricing or a date for full general availability.

OpenAI’s previous built-in browser used a separate browsing session and could not directly access a user’s existing logged-in Chrome environment. The new extension allows Codex to work with real accounts and workflows spanning multiple tabs, including services such as Gmail and Salesforce. This moves AI agents beyond offering advice to performing tasks, while increasing the risks of account-data leaks and unintended actions.

As of July 20, 2026, OpenAI had launched the Codex Chrome extension. Once installed, it can be invoked with “@Chrome” in Work mode or Codex to process cross-page tasks within a tab group in the background. Installation may require eight categories of permissions, including access to read and change data on all websites and view browsing history. However, confirmation is still required by default for each new domain, and users can configure allowlists and blocklists.

OpenAI Codex is an AI coding agent that can read and write files, run commands, test code and create commits in an isolated environment, turning natural-language requests into verifiable development workflows. Codex integrates models from the GPT-5.5 family and is available across command-line, desktop and cloud environments. Access is priced through ChatGPT subscriptions rather than as a one-time software purchase.

As of July 2026, OpenAI had also launched a Codex Chrome extension that can test web apps directly, capture context across tabs and allow multiple agents to work on tasks in parallel. Codex is available through plans including ChatGPT Plus at $20 a month, Pro at $200 a month and Business. Actual usage limits and available models vary by plan.
