Undetectable AI

Undetectable AI is a content analysis suite built around two core tools: an AI detector that scans text and flags specific AI-generated sentences, and an AI Humanizer that rewrites those flagged sections with more varied sentence structure and vocabulary. The site also ships an AI image detector, plagiarism checker, paraphraser, essay writer, and an SEO content writer, plus a Chrome extension for using the tools directly in the browser.

Detector.io

Detector.io is a multi-AI-detection dashboard that aggregates results from five different AI checkers (GPTZero, Winston AI, AIDetector.pro, ZeroGPT, and its own model) in one place. It allows users to submit text once and receive a side-by-side comparison of AI likelihood scores, sentence-level highlights, and a built-in humanizer to refine flagged content. It is designed for students, teachers, recruiters, marketers, and SEO teams to verify content authenticity and avoid false confidence from relying on a single detector.

PaperBleach

PaperBleach is an AI-powered text humanization tool that rewrites AI-generated content from models like ChatGPT, Claude, and Gemini to make it sound more natural and human-like. It includes a built-in AI detector to score the rewritten text against common detection systems like GPTZero, Turnitin, Copyleaks, and ZeroGPT.

Lunchbreak AI

Lunchbreak AI is a browser-based writing safety net for anyone who drafts with ChatGPT, Claude, Gemini, or other AI assistants and wants the final work to genuinely read as their own. It combines an AI-detection checker with a humanizing rewrite engine, targeting the phrasing patterns detectors commonly react to, such as uniform sentence lengths, stock transitions, and hedging language. The service is positioned as a final review tool before submitting essays, assignments, or papers.
