What you need
- A Mac running macOS 12 (Monterey) or later.
- Google Chrome — download here if you don't have it.
- A Google account you are willing to sign into (the personalized side of the comparison).
- The extension
.zip— download it here if you haven't yet. - About 10–15 minutes.
1. Unzip the extension
-
Open Finder and navigate to wherever you saved
ai-scapes-extension.zip(usually~/Downloads). -
Double-click
ai-scapes-extension.zip. macOS Archive Utility unzips it next to the original, producing a folder namedai-scapes-extension. -
Move the unzipped folder somewhere stable, for
example
~/Documents/ai-scapes-extension. Chrome loads the extension from this folder on disk — if you delete or move it later, the extension stops working. -
Open the folder once and confirm you can see
manifest.jsonat the top. That file is what tells Chrome how to load the extension.
manifest.json should be at the top level.ai-scapes-extension followed by another nested folder of
the same name, use the inner folder — it is the one that
contains manifest.json directly.
2. Open Chrome's extensions page
- Open Google Chrome.
-
In the address bar, type
chrome://extensionsand press Return. - In the top-right corner, toggle Developer mode ON.
chrome://extensions.3. Load the unpacked extension
- Click Load unpacked (top-left, after enabling Developer mode).
-
A Finder window opens. Navigate to the folder you placed in step 1
(e.g.
~/Documents/ai-scapes-extension) and click Select. -
The AI-scapes experiment card should appear with
its blue logo. If you see a red error banner, the wrong folder was
selected — re-select the folder that contains
manifest.json.
4. Allow the extension in Incognito
- On the AI-scapes card, click Details.
- Scroll down to find the Allow in Incognito toggle and switch it ON.
5. Start the study
-
Click the puzzle-piece icon in the Chrome toolbar, then pin
AI-scapes experiment for easy access.
Pinning the extension makes the icon visible in the toolbar. - Click the AI-scapes icon. You will be taken through a short consent form, then a setup page that confirms you are signed into Google and that incognito access is enabled.
- Click Start study. The extension will open four search windows in sequence — please leave them open until the extension closes them automatically.
Troubleshooting
"Failed to load extension" error
You picked a folder that does not contain
manifest.json at the top level. Re-select the folder
from step 1 — typically the one named ai-scapes-extension
whose contents include manifest.json,
experiment.html, and an icons/ folder.
The Incognito toggle has no effect
Quit Chrome completely (Cmd+Q, not just close the window) and re-open it. The incognito permission is read at startup.
I want to uninstall later
Return to chrome://extensions and click
Remove on the AI-scapes card. You can also delete
the folder you placed in step 1.
