OpenAI has launched Computer History in theChatGPT desktop appfor Mac, giving the AI model access to everything you do across apps and websites to build a persistent, searchable memory.
The feature replaces the earlier Chronicle research preview that OpenAI introduced in April 2026. Where Chronicle relied on periodic screenshots, Computer History takes a fundamentally different approach: it logs interaction events such as clicks, keystrokes, keyboard shortcuts, and app switches, without ever capturing your screen or audio.
Computer History is rolling out globally now for ChatGPT Pro, Business, and Enterprise users. It isnot availablein the European Economic Area, the United Kingdom, or Switzerland, a delay that hints at the regulatory friction this kind of feature invites.
For a platform that now servesnearly one billion weekly active users, any new feature that records user behaviour at this scale deserves scrutiny. Computer History is undeniably useful. It is also a voluntary surveillance system that OpenAI itself warns comes with security risks.
What Is ChatGPT Computer History?
Computer History is a new opt-in capability inside the ChatGPT Mac desktop app. It converts your recent activity across apps and websites into a searchable timeline and persistent memory that both ChatGPT and Codex can draw on.
Once enabled, the feature captures an interaction-event stream from whichever apps and websites you allow. These events get periodically summarized into text and stored as local memory files. You can then ask ChatGPT natural questions about your recent work, resume tasks where you left off, and even turn repeated workflows into automated skills.
The critical distinction from Chronicle:Computer History does not capture screenshots, screen recordings, microphone input, or system audio. Private-mode browsing activity is also excluded. OpenAI has described this as a rebuilt system rather than a simple rename of Chronicle.
Computer History is available forChatGPT Pro, Business, and Enterpriseusers. Free and Plus subscribers do not have access. Business and Enterprise users also need an administrator to explicitly grant workspace access before they can individually opt in.
How Computer History Actually Works
The technical workflow behind Computer History breaks down into several stages.
Data capture.The feature hooks into macOS accessibility APIs to log interaction events. That covers mouse clicks, keystrokes, keyboard shortcuts, and app-switching behaviour. You control which apps and websites feed into the system. You can block specific sources or whitelist only the ones you want included.
Local processing.Interaction events are saved temporarily on your Mac within the ChatGPT App Group container. These files are retained for up to 48 hours before being deleted.
Server-side processing.During that 48-hour window, the event files are sent to OpenAI servers for processing. OpenAI uses them to generate memory summaries, which are then stored locally as plain-text Markdown files on your Mac. OpenAI states it does not retain the event files after processing unless required by law and does not use them for model training.
Timeline and memory.Generated memories appear in a timeline view under Settings, grouped by day and time. Each entry shows a summary of what you did, which apps contributed, and sometimes a suggested skill or automation based on repeated patterns.
Controls.You can pause and resume collection from the macOS menu bar, clear the last 10 minutes, last hour, last day, or all history. Once cleared, the interaction events and any memories created from them are permanently deleted.
Computer History vs Microsoft Recall vs Chronicle
Computer History enters a growing category that some industry observers call “observational AI,” where AI systems passively monitor your desktop activity to build context. Microsoft’s Recall is the most direct competitor.
| Feature | Computer History | Microsoft Recall | Chronicle (Deprecated) |
| Platform | macOS only | Windows 11 (Copilot+ PCs) | macOS only |
| Data capture | Interaction events (clicks, typing, shortcuts) | Screenshots every few seconds | Screenshots + OCR |
| Screen capture | No | Yes | Yes |
| Audio capture | No | No | No |
| Local encryption | No (plaintext Markdown) | Yes (BitLocker + Windows Hello) | No |
| Default state | Opt-in | Opt-in (changed after backlash) | Opt-in |
| Cloud processing | Yes (events sent to OpenAI, deleted after processing) | No (on-device NPU) | Yes |
| AI integration | ChatGPT + Codex | Windows Copilot | ChatGPT |
| Prompt injection risk | Increased (OpenAI warned) | Lower (local processing) | Unknown |
| Availability | Global (except EEA/UK/CH) | Windows 11 Copilot+ PCs | Discontinued |
The comparison reveals a core design trade-off. Recall processes everything locally on dedicated neural processing hardware and encrypts stored data. Computer History skips screenshots entirely but sends raw event data to OpenAI servers for processing and stores generated memories as unencrypted plaintext files. Both approaches made the feature opt-in from day one, a lesson likely drawn from the significant backlash Microsoft faced when Recall was initially designed as opt-out.
The Security Risks OpenAI Warns About
OpenAI itself flags two significant risks in its official documentation for Computer History.
Prompt injection.OpenAI explicitly warns that enabling Computer History widens the prompt injection attack surface. Because the feature feeds content from every allowed app and website directly into the model’s context, a malicious webpage could embed hidden instructions that ChatGPT or Codex might execute.
This is not a theoretical concern. Security researchers have previously demonstrated that ChatGPT’s memory system can be exploited through prompt injection to exfiltrate personal data. With Computer History expanding what enters the model’s context window to include activity acrossevery allowed app and website, the attack surface grows substantially.
Unencrypted local storage.OpenAI acknowledges that the files Computer History generates may hold sensitive data and are stored without encryption. Any other program running under your macOS user account could potentially read them. The generated memories live as plain-text Markdown files under~/.codex/memories/extensions/skysight/, accessible to any process with your user-level permissions.
The EU delay as a regulatory signal.The decision to exclude the EEA, UK, and Switzerland from the initial rollout suggests OpenAI anticipates friction with European data protection regulators. Given that Computer History captures granular user behaviour data, processes it on OpenAI servers, and stores it unencrypted locally, this delay is not surprising.
OpenAI also advises users to turn Computer History off during communications with other people unless they have prior express consent, and to consider pausing or excluding apps that contain sensitive health, financial, or personal information.
Should You Enable Computer History? A Decision Framework
The answer depends on how you work and what kind of data crosses your screen.
- You are a developer who works across multiple tools and wants cross-app context for ChatGPT to reference when you resume tasks
- You work in non-sensitive content (writing, design, project management) and want a searchable record of your workflow
- You already use ChatGPT Pro and are comfortable with OpenAI’s data handling practices
- You want ChatGPT to suggest automations based on your repeated workflows
- You regularly handle financial, health, or legal data on your Mac
- You share your Mac with other users whose activity could be captured
- You work in an industry with strict data governance requirements
- You are concerned about unencrypted files containing your interaction history sitting on your filesystem
- You want your data processed entirely on-device (Microsoft Recall does this)
For enterprise administrators:Before enabling workspace-wide access, establish a clear policy about which roles and teams should opt in. The prompt injection risk alone makes blanket enablement premature for teams handling sensitive client data.
What This Means for the Future of AI
Computer History is the clearest signal yet that the AI industry is moving from reactive assistants to observational systems. The model is no longer waiting for you to type a prompt. It is watching how you work and using that context to anticipate what you need.
Microsoft started this trend with Recall. OpenAI has now followed with Computer History. Both companies are betting that users will trade some privacy for a more context-aware AI experience.
This shift will define the biggest privacy debate in AI through 2026 and 2027. The tools themselves are genuinely useful for productivity. The infrastructure underneath them, specifically unencrypted local storage, cloud processing of behavioural data, and expanding prompt injection surfaces, has not caught up with the ambition.
OpenAI learned from Microsoft’s Recall backlash by making Computer History opt-in from day one. But the unencrypted local storage and the self-acknowledged prompt injection risk suggest that lesson was only half-learned.
The real question is not whether Computer History makes ChatGPT smarter. It obviously does. The question is whether storing your unencrypted interaction data locally for 48 hours and sending it to OpenAI servers is a reasonable price for that intelligence.
Computer History is a voluntary feature inside the ChatGPT Mac desktop app. Once enabled, it logs interaction events (mouse clicks, keystrokes, shortcuts, app switches) from whichever apps and websites you allow, then organises them into a searchable timeline and persistent AI memory. It does not capture screenshots, audio, or screen recordings.
Is ChatGPT Computer History safe?
OpenAI itself warns that Computer History increases prompt injection risk and stores files unencrypted locally. Other programs running under your macOS user account may access these files. OpenAI recommends pausing the feature when handling sensitive health, financial, or personal data, and when communicating with others without their consent.
What is the difference between ChatGPT Computer History and Chronicle?
Computer History is the successor to the Chronicle research preview. Chronicle worked by taking periodic screenshots and indexing them with OCR. The new system drops screen capture entirely and logs interaction events (clicks, keystrokes, shortcuts) instead. OpenAI describes it as a ground-up rebuild, not a rename.
How does ChatGPT Computer History compare to Microsoft Recall?
Both features track desktop activity to build AI context, but they work differently. Computer History records interaction events and sends them to OpenAI servers for processing. Recall captures screenshots and processes everything locally on-device using a dedicated neural processing unit. Recall encrypts stored data with BitLocker and Windows Hello. Computer History stores memories as unencrypted plaintext files.
Who can use ChatGPT Computer History?
Computer History is available forChatGPT Pro, Business, and Enterpriseusers in the ChatGPT Mac desktop app. It is not available for Free or Plus subscribers, and it is currently excluded from the European Economic Area, UK, and Switzerland.
How do I enable or disable ChatGPT Computer History?
Open the ChatGPT desktop app on macOS, go to Settings, then Integrations, and select Computer History. You can turn it on or off, choose which apps and websites contribute, and pause or resume collection from the macOS menu bar at any time.
