You know that thing you did on your Mac yesterday? The terminal command. The file path. The obscure setting you tweaked in VS Code. Gone. Vanished from memory. Now you’re re-Googling, re-reading docs, re-doing the work.
ChatGPT can now remember it for you.
The new Computer History feature on the ChatGPT Mac app watches what you do and lets you ask about it later. Opt-in only. Privacy-first. And genuinely useful if you know how to set it up.
What Is ChatGPT Computer History?
Think of it as a rewind button for your digital life. The feature lives in the ChatGPT desktop app for Mac. Once enabled, it captures your screen activity — the apps you use, the text you type, the commands you run — and makes it queryable through chat.
How It Differs from Regular ChatGPT Memory
Regular memory stores facts you explicitly tell ChatGPT. “I prefer dark mode.” “My name is Sarah.” Computer History is different. It observes. You don’t tell it anything. It watches you work and builds a searchable timeline of your actions.
Privacy First — Opt-In Only
OpenAI made this opt-in for a reason. Nothing gets captured until you flip the switch. You choose which apps to monitor. You can delete individual entries or nuke the entire history. The data stays on your Mac unless you explicitly share a screenshot in chat.
Requirements Before You Start
ChatGPT Plan Needed
Computer History requires ChatGPT Plus, Pro, or Team. Free tier doesn’t get it. If you’re on the free plan, this feature won’t appear in your settings.
macOS Version Requirements
You need macOS 14 (Sonoma) or later. The feature uses Apple’s ScreenCaptureKit framework, which only exists on newer macOS versions. On Ventura or older? You’re out of luck until you upgrade.
ChatGPT Desktop App Installation
Browser version won’t work. You need the native Mac app from chatgpt.com/download. The menu bar icon is your gateway — that’s where the Computer History toggle lives.
How to Enable Computer History (Step by Step)
Step 1: Open ChatGPT Settings
Click the menu bar icon (top right of your screen). Choose “Settings” from the dropdown. Or press Cmd + , with the app focused.
Step 2: Find the Computer History Toggle
Navigate to the “Data Controls” tab in the left sidebar. Look for “Computer History” — it’s a distinct section, not buried under general memory settings. Toggle it on.
Step 3: Grant macOS Permissions
macOS will prompt for screen recording permission. This is normal. Click “Open System Settings” when prompted. Find ChatGPT in the list. Enable the toggle. You’ll need to quit and reopen ChatGPT for it to take effect.
Step 4: Choose What to Track
Back in ChatGPT settings, you’ll see a list of apps. By default, everything is selected. Uncheck apps you don’t want monitored — browsers with sensitive data, password managers, banking apps. Keep your code editor, terminal, and research tools checked.
How to Actually Use It
Prompt Examples That Work
Once enabled, wait a bit. Do some work. Then try these:
- “What terminal command did I run yesterday around 3 PM?”
- “Show me the file paths I copied in VS Code this morning”
- “What was that error message I got in Chrome an hour ago?”
- “Summarize my research from the last two hours”
The key: be specific about time and context. “What did I do?” returns a firehose. “What Python script did I edit after lunch?” returns gold.
What It Captures (And What It Doesn’t)
Captures: text you type, text you copy, window titles, app switches, URLs visited, code you write, commands you run.
Doesn’t capture: password fields (masked), incognito/private browsing, apps you unchecked in settings, anything before you enabled the feature.
Combining with Voice Mode
Here’s where it gets fun. Enable voice mode (Cmd + Shift + V). Ask “What was that thing I just did?” while looking at your screen. ChatGPT sees your screen and has the history. Double context. Try it during a debugging session — you’ll wonder how you lived without it.
Managing Your History
Viewing Your Computer History
In Settings > Data Controls > Computer History, click “View History.” You get a timeline: app icons, timestamps, preview snippets. Click any entry to see the full captured context.
Deleting Specific Entries
Hover an entry. Click the trash icon. Gone. Useful for that one time you accidentally copied a password before the field masked it.
Turning It Off Completely
Toggle off in Settings. History remains stored until you delete it. To purge everything: Settings > Data Controls > “Delete all Computer History.” Nuclear option. Irreversible.
Pro Tips for Power Users
Best Prompts for Developers
- “What git commands did I run in the last hour?”
- “Show me the exact error traceback from my last test run”
- “What files did I modify in the auth module today?”
- “Find the Stack Overflow link I opened while debugging the login issue”
Research Workflow Integration
Researching a topic? Don’t bookmark everything. Let Computer History track your browser tabs. At the end of the session: “Give me a summary of all the articles I read about [topic] with key points and URLs.” Boom. Instant literature review.
Privacy Settings Worth Tweaking
Exclude your browser entirely if you handle sensitive data. Use a separate browser profile for research and only track that one. Or exclude Slack/Teams if your workplace has policies against AI monitoring. Granular control exists — use it.
Takeaway
Enable Computer History today. It takes two minutes. Try asking “What terminal command did I run yesterday?” and watch it work. Then try “Summarize my coding session from this morning.” That’s when it clicks — you’ve been wasting time re-remembering things your computer already knew.
The feature isn’t perfect. It’s Mac-only. It needs a paid plan. But for the workflows it covers? It’s the first AI feature that genuinely feels like a superpower instead of a demo.
Stop re-Googling. Start asking.
