AI Detector By Custom Writings vs AI Detector & Humanizer (formerly AI Detector - Text Validator)

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.

AI Detector & Humanizer scans pasted text for AI authorship, then rewrites robotic passages so they read naturally on iPhone, iPad, Mac, and Apple Vision. The App Store listing claims third-party study backing and support for GPT-5.2 and Gemini output, with tones like Formal, Friendly, and Conversational. Detection returns confidence scores tuned for ChatGPT, Gemini, and Claude text.

Standalone detectors flag AI but leave you to fix the prose yourself. This app pairs detection with humanizing rewrites, watermark removal, and a text enhancer for clarity in one mobile workflow. The developer states data is not stored and no login is required, which matters for students submitting drafts from their phones.

Students, teachers, editors, and job seekers use it to check essays, emails, and job applications before sharing. Free access covers basic humanizing and detection; credit packs unlock unlimited rewriting, premium tones, and an ad-free Pro experience through in-app purchases.
