Preface by webmaster: This is a repost of a blog by Jonathan Bailey at Plagiarism Today titled “The Gradient of AI Usage.” He identifies ten excellent examples of content generation that range from entirely human authorship to entirely AI-Generated content using only prompts. This blog is reposted with permission.
It should be noted that Jonathan’s post was discovered after we had created the “Copyrightability Gradient” graphic that was included in a blog we initially posted on April 16, 2025. The blog has subsequently been updated to include new reports out of the US Copyright Office.
