Context
Computer History turns activity from apps and websites a user allows into memories and a timeline of past work, which the announcement says can help build skills from frequent tasks. OpenAI's documentation describes an interaction-event stream built from text and exposed through macOS accessibility features. It does not include screenshots or record microphone or system audio.
The feature is off by default, and history starts only after a user turns it on. Users can exclude apps and websites, pause collection, and delete timeline items or clear history; clearing history also deletes memories created from those events. Processing is split: temporary event files are saved on the Mac, OpenAI processes them on its servers to generate memories, and the memories are stored on the Mac as Markdown files.
- context window — The maximum amount of text a model can consider at once — its working memory for the current conversation or task.
- token — The chunk of text a model reads and writes in — roughly three-quarters of a word — and the unit AI usage is billed in.
