OpenAI introduced Computer History for ChatGPT's MacOS app, allowing it to track clicks, typing, and app switches to build a timeline of user activity. Available for Pro, Business, and Enterprise subscribers, the opt-in feature raises privacy concerns as it stores unencrypted data locally and expands prompt injection risks.

OpenAI Introduces Computer History for ChatGPT Mac App

OpenAI launched Computer History this week, a new feature for the ChatGPT Mac app that tracks user activity across applications and websites to create a detailed timeline

1

. Available exclusively for Pro, Business, and Enterprise subscribers, the opt-in feature builds on ChatGPT's existing Memories capability by logging interactions to help the AI understand user workflows and suggest automations

2

. The feature replaces the earlier Chronicle research preview, which relied on screenshots similar to Microsoft Recall

Computer History uses MacOS accessibility APIs to capture "clicks, typing, keyboard shortcuts, app switches, and context" rather than screenshots, video, or audio

1

. The system periodically synthesizes these interaction events into text summaries and local memory files, organizing them into a timeline by day and time

3

. Users can ask ChatGPT questions like "What was I working on before my last break?" or "Give me a list of tasks I've worked on today and their status"

4

Privacy Concerns and Security Implications

The feature has sparked privacy concerns despite OpenAI's assurances about data handling. Computer History files are stored locally but remain unencrypted, meaning "other programs running as your macOS user may be able to access them," according to OpenAI's explicit warning

1

. Temporary memory files are retained for 48 hours before deletion, though users can manually delete entries earlier

While OpenAI claims it doesn't retain activity files after processing unless legally mandated and doesn't use them for training, the interaction events are sent to OpenAI servers to generate memories

5

. The feature also increases vulnerability to prompt injection attacks, as OpenAI acknowledges: "if you visit a website containing malicious instructions, ChatGPT or Codex might follow those instructions"

5

.

OpenAI advises users to "turn it off during communications with other people unless you have their prior express consent" and to "consider pausing it or excluding apps that contain sensitive health, financial, or personal information"

5

. Ari Weinstein, Product and Engineering manager at OpenAI, confirmed that Computer History automatically ignores content in incognito or private browser tabs

2

.

User Control and Availability

Computer History is disabled by default, requiring active user opt-in through Settings > Integrations > Computer History

3

. Pro users can enable it independently, while Business and Enterprise users need administrator approval

1

. Users can independently select which applications and websites to track, pause tracking at any time, and view or delete history entries

The feature is rolling out globally in most regions but is not yet available in the EEA, Switzerland, and the UK, with access expected in the coming weeks

3

. There's currently no indication when or if Windows or mobile versions will launch

.

Technical Implementation and Costs

Computer History creates tokens for summarizing and memory creation, potentially impacting users' token budgets and context window sizes

1

. The feature uses fewer tokens and offers more privacy controls than Chronicle, according to OpenAI

3

. In a demo video, OpenAI's Dominik Kundel showed the app looking up the last document edited, checking if it was shared via Slack, and delivering a morning activity recap

2

.

The timeline displays each captured item with a title, summary of activity, apps or websites used, suggested skills for repeatable work, and options to view the memory file in Finder or delete it entirely

3

. This data collection approach represents what some critics describe as "keylogging and event capture," marking a shift from screenshot-based monitoring to interaction-based tracking
