AI Detector By Custom Writings vs StealthWriter

CustomWritings runs a free AI detector inside its HowToWrite hub where students can paste text or upload DOC, TXT, PDF, and PowerPoint files to see what share of a paper looks machine-written. The checker returns an overall percentage and color-codes passages as likely or highly likely AI output, then lets you download a PDF report. It also ships as a browser extension for checking page content without leaving the site you are on.

Most standalone detectors sell themselves as neutral scanners. This one is built by an essay writing company that has offered academic help for 20 years and added combined AI and plagiarism screening to its own order checks in 2023. That parent service context shows up in the framing: the tool targets students who want to self-check before turning work in, not enterprise teams auditing marketing copy. The trade-off is independence, but the upside is a detector sitting next to free plagiarism, citation, and writing guide tools on the same domain.

Students prepping assignments, teachers reviewing suspicious submissions, and writers who lean on grammar tools all have reason to run a pass here. The FAQ notes that heavy grammar assist and stiff, template-like phrasing can sometimes trip the model even on human drafts, so shorter pieces under roughly 275 words may return less reliable scores than a full essay page.

StealthWriter is an AI detection and text humanization web app that rewrites drafts from ChatGPT, Claude, Gemini, and similar tools into natural human prose. The homepage pairs a free AI detector (up to 500 words, no account) with a humanizer that returns polished text in seconds. Ghost 5.2 Mini is the default lightweight model, and Ghost 5.2 Pro targets stronger coherence and readability.

Most AI humanizers focus on beating detectors and sacrifice readable output. StealthWriter pairs the humanizer with a built-in V2 detector and Deep Scan sentence highlighting so you see flagged lines before and after rewriting. Click any sentence to pick from alternative phrasings at ten rewrite intensity levels.

Students, bloggers, marketers, copywriters, and researchers who draft with AI assistants but need the final copy to read naturally. The free tier covers light daily use, and paid plans scale from 50 to 2,000 humanizations per day with up to 5,000 words per input.
