All 8 alternatives, ranked

evidence / 100
1
The dominant academic plagiarism checker, with an AI-writing indicator built into its similarity reports.

+ Already deployed at most universities, so AI scores appear inside the workflow instructors use.
− No individual access, and its AI indicator has led to disputed accusations against students.

2
QuillBot Free tier
A paraphraser, grammar checker, summarizer and AI detector/humanizer popular with students.

+ The paraphraser's mode slider (fluency, formal, simple, creative) is the fastest way to rework a clumsy paragraph.
− Paraphrased text sometimes changes meaning, and its humanizer and detector are unreliable against serious detection tools.

Plagiarism and AI-content detection with LMS integrations and an API, used by schools and enterprises.

+ Supports 30+ languages and integrates with Canvas, Moodle and Blackboard.

Undetectable AI Free tier
Rewrites AI text to read as human and scores it against common detectors.

+ Shows detector scores before and after, so the claim is checkable.
