AI Scanner

Free to use and with no registration required, AI Scanner is an AI text detector you can open and run a check in right away.

Paste in writing and the tool looks for AI-like patterns, then marks suspicious lines so you can see which parts may need revision.

It also handles blended drafts, such as passages first produced with AI and later edited by a person, which is where many simple checkers struggle.

Students and educators are the clear audience, since AI Scanner gives a quick way to review possible AI signals in an essay or assignment.

The interface is plain and results come back fast.

It is also listed alongside paraphrasing, plagiarism checking and humanizer functions, so see it as a first-pass check rather than a final verdict on authorship.
