Step-by-step: Find AI-generated code with AboutCode

In this tutorial, we first generate code using ChatGPT, then scan the generated code in ScanCode using the MatchCode pipeline.

• Visit chatgpt.com

• Enter this prompt to generate code:

Write JS code that is similar to https://github.com/isaacs/inherits/

• The results will look something like this:

• Click “Copy” button to copy the generated code then paste this in a text editor to save the generated code to a file named “foo.js”:

• Next, open your ScanCode.io URL and click on the “New Project” button.

• Click “Drop files over here (or click)” and upload the saved “foo.js” file.

• Then select the initial “scan_codebase” pipeline and click the “Create” button:

• Click “Add pipeline” button.

• Then select the “fingerprint_codebase” and cliem the “Add pipeline” button.

• Repeat with the “match_to_matchcode” pipeline:

• When the scan is done, click the “Resources” link to see the match results

• You can see the file was matched to the “pkg:github/isaacs/inherits@v2.0.3” PURL. This is for this package: https://github.com/isaacs/inherits/

• Click on “pkg:github/isaacs/inherits@v2.0.3” package link.

• From there click on the “Resources” tab:

• Click the “foo.js” link to see the file details.

• Click on the “Viewer” tab to see the file content.

• Click “Matched Snippets” sub-tab of the viewer to see the highlighted matched code:

• The AI-generated code is highlighted as matched code below:
