OpenAI drops Chronicle for Codex macOS

OpenAI releases Chronicle, a research preview for the Codex macOS app that uses periodic screen captures to build an ambient context layer, allowing the AI to understand user workflows without manual input.

// ANALYSIS

Chronicle marks a significant step toward "invisible" prompting where AI context is automatic rather than explicit. Periodic screenshots are converted to local summaries to provide situational awareness, eliminating the need for manual input. This release positions Codex as a comprehensive workspace, though always-on screen monitoring remains a sensitive privacy topic.
