ZeroGPT alternatives

+ 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.

+ Shows detector scores before and after, so the claim is checkable.
− Using it to pass a school or client check breaks most of their rules, and rewrites flatten nuance.

+ Combines AI detection, plagiarism, fact-check and readability scans with team seats and a full-site scan.
− Known for aggressive detection that flags human writing, with no free tier.

+ Produces a shareable report and reads scanned documents with OCR.
− Paid, and like every detector it mislabels non-native writing.
