ZeroGPT
ZeroGPT analyzes text and returns an estimate of whether it resembles AI-generated writing. Its interface can highlight sentences and display a document score. The site also offers separate tools for plagiarism checking, paraphrasing, summarizing, and translation. An AI-detection result and a plagiarism result answer different questions.
Use a score as a review prompt
Paste a text sample and keep the original version alongside the result. Inspect highlighted passages and compare them with drafts, revision history, quotations, and the author’s explanation of their process. A percentage alone does not establish who wrote a text or which tool they used. Do not convert a detection score into proof of misconduct or a verified authorship claim.
For editorial review, the useful next step is to check unsupported claims and copied passages directly. Rewriting until a detector gives a lower score does not verify the underlying facts or sources.
Limits and paid access
The published free comparison currently allows 15,000 characters per AI-detection check. Paid plans increase allowances and can add batch processing, PDF reports, or other tools. The quotas for plagiarism and writing tools differ from the AI detector’s character limit. API access is priced separately through a funded balance.
Check the live plan comparison before purchasing because billing period and selected tier affect the offer. This listing does not adopt the vendor’s advertised accuracy figures or claim an independent detector benchmark.
