AI Detector & Humanizer vs Grammarly

AI Detective is a cross-platform app that detects AI-generated text from a camera, pasted text, files, or website URLs. It also includes a humanizer to rewrite text as more human-like, plus readability and plagiarism checks.

Grammarly is an AI writing assistant that checks grammar, spelling, punctuation, and style in real time across browsers, desktop apps, and mobile keyboards. It integrates directly into Gmail, Google Docs, Microsoft Word, Slack, and thousands of other websites via a browser extension. Beyond basic correctness, Grammarly analyzes tone and clarity, suggesting rewrites to make writing more concise, confident, or friendly depending on the context and audience selected by the user. GrammarlyGO adds generative AI features for drafting emails, replying to messages, and rewriting passages on demand, while Grammarly Business adds brand style guides and analytics for teams that need consistent written communication across an organization.
