OpenAI has rebuilt one of ChatGPT’s more privacy-sensitive features from the ground up — and, tellingly, changed its entire data-collection approach in the process. The screenshot-based “Chronicle” research preview is gone, replaced by a new feature called Computer History that logs interaction events instead of capturing your screen.
From Screenshots to Event Logs
Chronicle launched as an opt-in research preview around April 2026, primarily for ChatGPT Pro subscribers using the Codex desktop app on Mac. It worked by periodically capturing screenshots of your screen in the background, sending them to OpenAI’s servers for OCR and visual analysis, and generating text summaries stored locally as memories — giving Codex and ChatGPT persistent “screen context” about what you’d been working on, without you having to explain it in every prompt.
The problem was the obvious one: a feature that periodically screenshots your desktop and ships those images off for analysis draws immediate, understandable comparisons to Microsoft Recall — the Windows feature that faced heavy backlash in 2024 over exactly this kind of always-on visual surveillance. Chronicle wasn’t available in the EU, UK, or Switzerland, likely for related regulatory-exposure reasons, and it carried elevated prompt-injection risk given that visual content was being fed into the pipeline.
Computer History, according to OpenAI’s own documentation and corroborating reporting from The Register and 9to5Mac, does the same underlying job — giving ChatGPT and Codex a timeline of your recent activity to draw context from — but through a fundamentally different mechanism.
How Computer History Actually Works
Per OpenAI’s official documentation, Computer History uses macOS accessibility APIs to log interaction events: clicks, typing, keyboard shortcuts, app switches, and other context macOS accessibility APIs expose. Critically, according to OpenAI’s own docs, there are no screen captures, no screen recordings, no microphone input, and no system audio involved at any point. Private browsing sessions are excluded from collection.
The events feed into a searchable local timeline that ChatGPT and Codex can reference for cross-session context — letting you ask things like what you were doing before a break, find a document or conversation “the way you remember it,” or have the system notice a repeatable workflow and suggest turning it into a skill or automation.
Availability is deliberately narrow and opt-in. Per OpenAI’s documentation, Computer History is off by default for ChatGPT Pro, Business, and Enterprise users in the ChatGPT desktop app on macOS. Pro users can turn it on themselves; Business and Enterprise users need an administrator to explicitly grant access first, after which individual members can choose to enable it. It requires OpenAI’s separate Memories feature to function, and it is not available with an API key or via Amazon Bedrock. Like its predecessor, it’s not currently available in the European Economic Area, Switzerland, or the UK.
Users retain meaningful control: you can see and pause collection from the macOS menu bar, inspect or delete specific captured items or generated memories, and clear recent history in increments — the last 10 minutes, hour, day, or everything at once.
Why This Framing Matters
OpenAI’s own documentation is explicit that Computer History “replaces the earlier Chronicle research preview, but it is a rebuilt system rather than a rename.” That’s a meaningful distinction OpenAI is choosing to make publicly: Chronicle used screenshots; Computer History records interaction events and does not capture screen or audio content at all. This isn’t a rebrand with a privacy-friendlier name slapped on the same underlying mechanism — the actual data being collected and how it’s collected has changed.
Reporting from The Register and 9to5Mac frames this squarely as OpenAI trying to get ahead of a Recall-style backlash before it happens, rather than responding to one after the fact. Given how much reputational damage Microsoft absorbed over Recall’s initial design, building the successor to Chronicle around an explicitly screenshot-free architecture — and being loud about that distinction in the product documentation — reads as a deliberate, proactive choice rather than incidental.
What This Means for Agentic Workflows
For practitioners building on top of ChatGPT/Codex, the practical upshot is that persistent cross-session context is becoming a first-class capability, just built on a data-collection method with a meaningfully smaller attack surface and lower regulatory friction than screen capture. If you’re evaluating whether to enable Computer History for your own workflow, the trade-off is straightforward: you’re giving up screenshot-level visual fidelity (which could, in theory, capture nuance an accessibility-event log misses) in exchange for a system that never captures your screen content, audio, or keystrokes’ actual text at the pixel level — only interaction metadata.
If you’re on a Business or Enterprise ChatGPT plan, note that admin approval is a hard prerequisite before individual users can opt in at all — this isn’t something an individual employee can quietly enable on their own in a managed workspace.
Verification
This report is confirmed via The Register’s August 14, 2026 coverage plus independent corroboration from 9to5Mac’s August 13, 2026 piece, both describing the same feature, the same rollout tiers, and the same Chronicle-replacement framing. Both outlets, along with OpenAI’s own documentation, describe local, largely on-device event storage with no training-data use of the collected activity.
