Codex App: Appshots Brings Instant Mac Window Context via Double-Command
CodexCodex version 26.519 introduces Appshots, a macOS-exclusive feature that lets users send the frontmost application window directly to a Codex thread by pressing both Command keys simultaneously. The captured snapshot includes a screenshot and all available text from the target window, eliminating the need to manually copy-paste content or describe what is on screen. Appshots is currently macOS-only, requiring the platform's accessibility and screen-recording stack; Windows support is not available at launch.

New Feature: Appshots
Codex version 26.519 introduces Appshots, a new interaction model for providing real-time application context to the AI agent on macOS. The feature enables developers to share the state of any frontmost application window with Codex in a single gesture — pressing both Command keys (⌘⌘) simultaneously, or a user-defined custom hotkey.
How Appshots Works
When triggered, an Appshot captures two things from the frontmost window: a screenshot of the visible portion and all available text, including text the application exposes outside the current scroll area. This means Codex receives a complete picture of what the user is working on — whether it is a browser with a specific API error, a design tool with layout dimensions, or a terminal with a stack trace — without requiring any manual copying, pasting, or description.
The captured content is attached to the current Codex thread, where the agent can immediately act on it. For example, a developer might switch from their code editor to a failing test run in Terminal, press ⌘⌘ to capture the error output, then return to Codex for a targeted fix without breaking their flow.
Platform Availability
Appshots is a macOS-only feature at launch. It depends on the macOS accessibility and screen-recording stack, which has no equivalent on Windows. Users of the Codex desktop app on Windows receive all other features in version 26.519, but the ⌘⌘ shortcut is not available.
Positioning
Appshots positions Codex as a deeply integrated macOS tool — one that can observe and act on the user's full desktop context, not just the files open in an editor. It draws a direct line to Codex's broader computer use capabilities, making multi-app workflows significantly more fluid by removing the friction between seeing a problem and handing it off to the agent.
