OpenAI Launches Chronicle for Codex on Mac to Reuse On‑Screen Context

Periodic on-device screenshots to build memory raise fresh privacy questions.

Overview

  • OpenAI released Chronicle for its Codex Mac app as an opt-in research preview for ChatGPT Pro subscribers, with access not yet available in the EU, UK, or Switzerland.
  • The feature builds short-term memories from periodic screenshots of recent activity so Codex can understand references like “this” or “that” without users restating context.
  • Users must grant Screen Recording and Accessibility permissions, can inspect or edit the local memory files, and can pause or turn Chronicle off from the menu bar.
  • OpenAI and Codex’s lead say the current design consumes many tokens and can hit rate limits quickly, signaling an early-stage feature that may feel costly to run.
  • OpenAI says captures are processed in an ephemeral session, stored locally as unencrypted files, and older frames are auto-deleted, yet other apps can read those files and reporters are comparing the screenshot approach to Microsoft’s contentious Windows Recall.
