Overview
- OpenAI rolled out Chronicle as an opt-in preview for ChatGPT Pro subscribers using the Codex app on macOS.
- The tool records recent on-screen activity in the background and turns it into local Markdown summaries that Codex can use as context.
- OpenAI says original recording files are kept only for a short time and are automatically deleted after six hours.
- Users activate the feature by turning on Memories and Chronicle in Codex personalization settings and granting macOS screen-recording and accessibility permissions.
- The company warns of higher prompt-injection risk, unencrypted storage of summaries on the device, and faster consumption of usage quota.
