OpenAI's Chronicle Watches Your Screen to Power Codex
New macOS feature builds persistent memories from screen captures, giving Codex deeper awareness of what you're working on.
OpenAI just shipped Chronicle, a new feature that watches your screen and builds memories from those captures. The goal: make Codex significantly more context-aware about what you're actually doing on your machine.
Chronicle launched as a research preview exclusively for Pro subscribers on macOS. It arrives alongside a completely revamped version of Codex for Mac.
The feature represents what's being called the best implementation of AI-driven computer use to date. Instead of relying solely on what you explicitly feed into a prompt, Chronicle passively accumulates context from your workflow — building a running memory that Codex can tap into.
It's a bold move that pushes AI coding assistants from reactive tools into something closer to persistent collaborators. For now, it's limited to OpenAI's highest-paying tier, but the research preview label suggests broader rollout could follow.
