What Is OpenAI Codex and How People Use It
A cloud-based AI coding agent that handles data analysis, frontend builds, mobile apps, and automated code review.
Data analysis and visualization
Upload messy data and Codex turns it into clear analysis with charts and reports. It can even generate slide decks from your data automatically.
Building websites from designs
Give Codex a screenshot or Figma design and it converts it into responsive, working code. It even verifies the result visually.
Mobile app development
Codex can build and debug SwiftUI applications for iOS and macOS, accelerating mobile development.
Automated code review
Set Codex to review pull requests automatically, identifying bugs and regressions before human reviewers look at the code.
Rapid prototyping
From browser-based games to API integrations, Codex handles iterative development loops — building, testing, and refining code quickly.
