ChatGPT for Mac App Adds Optional Computer History Feature

OpenAI has introduced a new Computer History feature on the macOS version of its ChatGPT app. When enabled, the optional feature will record what users do on their Macs to build an explorable timeline that ChatGPT and Codex can use to improve their responses.

Computer History is only available for ChatGPT Pro, Business, and Enterprise users, but the feature is off by default on the macOS app. After enabling it, Mac users can control which apps and websites contribute to the personal history ChatGPT and Codex will have access to. They can also pause data collection, inspect their personal timeline, and delete their history at any time.

Overall, Computer History looks quite similar to the controversial Windows Recall feature that Microsoft introduced on Copilot+ PCs. And that’s probably why the feature is entirely opt-in.

Computer History builds on the Chronicle research preview with reduced token usage and more privacy controls.

A new timeline view gives you the ability to look back on your work and build skills from your frequent tasks.

From there or the menu bar, you can:

Computer History leverages OpenAI’s previous work on Chronicle, a research preview that used screenshots to build memories for its Codex tool. “Computer History replaces the earlier Chronicle research preview, but it is a rebuilt system rather than a rename,” OpenAI explained. “Computer History does not capture screenshots, screen recordings, microphone input, or system audio. Private-mode web browsing activity is never included.”

In terms of privacy and security, OpenAI explained that Computer History saves interaction events temporarily on Macs, and event files are isolated to prevent other apps from accessing them without explicit permission. However, these event files, which are deleted after 48 hours, are not encrypted by Computer History.

OpenAI also said that it “processes temporary event files on its servers to generate memories, which are then stored locally on your Mac.” However, the company explained that it “does not retain those event files after processing unless required by law and does not use them for training.”

Lastly, the company warned about increased prompt injection risks when Computer History is enabled. “If you visit a website containing malicious instructions, ChatGPT or Codex might follow those instructions,” OpenAI said.

Because Computer History files can contain sensitive information, aren’t stored in an encrypted state, and there’s some data shared with OpenAI, ChatGPT users may want to be very cautious about enabling Computer History. The feature can be turned on in Settings > Integrations > Computer history, but it’s currently not available in the European Economic Area (EEA), Switzerland, and the UK at launch
