GoKawiilOpenAI is giving ChatGPT and Codex a new way to learn from and remember how you use your Mac, even when that work happens outside the app.
ChatGPT Computer History is an upgraded replacement for Codex’s Chronicle research preview
The new Computer History feature builds a searchable timeline from activity across selected apps and websites.
OpenAI announced Computer History in Thursday’s desktop app changelog. The feature is off by default and must be enabled by each user, giving people control over which sources contribute to their history.
The release comes a month after Codex joined ChatGPT on the desktop. It also follows OpenAI’s experimental Chronicle feature from earlier this year.
OpenAI says Computer History actually replaces the Chronicle research preview, but calls it a rebuilt system rather than a simple rename.
Chronicle relied on screenshots. Computer History instead records interaction events exposed through macOS accessibility features, including clicks, typing, keyboard shortcuts, and switching between apps.
Today we're releasing Computer History in ChatGPT.
It lets ChatGPT learn from everything you do on your computer, so it can better understand how you work, finish tasks that you're in the middle of, and suggest skills and automations based on how you use your computer. pic.twitter.com/xnTq7hWH8O — Ari Weinstein (@AriX) August 13, 2026
