+ 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.
+ The detector is free and gives a per-sentence score.
− Detection is a side feature - the product is really autocomplete for agents.
+ 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.
+ Supports 30+ languages and integrates with Canvas, Moodle and Blackboard.
− Credit-based pricing is confusing, and false positives on edited human text are common.
+ Highlights which sentences look AI-generated and offers a Google Docs writing replay as supporting evidence.
− Like all detectors it produces false positives, particularly on non-native English writers.
