What you need
- A PC running Windows 10 or Windows 11.
- Google Chrome — download here if you don't have it.
- A Google account you are willing to sign into.
- The extension
.zip— download it here if you haven't yet. - About 10–15 minutes.
1. Unzip the extension
-
Open File Explorer (Win+E)
and go to wherever you saved
ai-scapes-extension.zip(usuallyDownloads). -
Right-click
ai-scapes-extension.zipand choose Extract All…. Pick a stable destination such asC:\Users\<you>\Documents\ai-scapes-extensionand click Extract. -
Open the extracted folder and confirm it contains
manifest.jsondirectly. Ifmanifest.jsonis one level deeper, use that inner folder for the next step.
manifest.json is at the top.
Why not double-click? Windows treats double-clicking
a zip as a "preview" — the files are not actually extracted. Chrome
cannot load an extension from inside the zip preview. Always use
Extract All.
2. Open Chrome's extensions page
- Open Google Chrome.
-
In the address bar, type
chrome://extensionsand press Enter. - In the top-right corner, switch Developer mode ON.
chrome://extensions).3. Load the unpacked extension
- Click Load unpacked (top-left of the page).
-
A folder picker opens. Navigate to the folder you extracted in
step 1 (e.g.
C:\Users\<you>\Documents\ai-scapes-extension) and click Select Folder. -
The AI-scapes experiment card should appear. If a
red error appears about
manifest.json, you picked the outer folder by mistake — go one level deeper and re-select.
4. Allow the extension in Incognito
- On the AI-scapes card, click Details.
- Scroll down and switch Allow in Incognito ON.
5. Start the study
-
Click the puzzle-piece icon in the Chrome toolbar, then pin
AI-scapes experiment.
Pinning the extension makes the icon visible in the toolbar. - Click the AI-scapes icon to begin the consent form and setup checks.
- Click Start study. Four search windows will open in sequence. Leave Chrome focused while they run; they will close themselves once each search finishes.
Antivirus / SmartScreen. Some Windows installs
flag unsigned developer extensions on first run. The
.zip we ship is the same source code published on our
public GitHub — it is not signed because Chrome only signs
extensions distributed via the Chrome Web Store. If your IT policy
blocks unpacked extensions, contact the lab so we can arrange an
alternative.
Troubleshooting
"Manifest file is missing or unreadable"
Chrome could not find manifest.json at the top of the
folder you selected. Open the folder in File Explorer, look for
manifest.json, and re-pick exactly that folder.
"This extension may have been corrupted"
Re-download the zip and extract it again — partial downloads can cause this. If it persists, switch off your antivirus's "scan extensions" feature temporarily.
