AI Detector By Custom Writings vs AI Content Detector | Copyleaks

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.

Copyleaks AI Content Detector flags text, images, and video that likely came from generative models, then shows where AI presence appears in the document. Educators, publishers, and compliance teams paste or upload content to get a percentage score, highlighted passages, and optional plagiarism matches in the same report through Copyleaks AI Logic.

Standalone AI checkers often ignore images or treat plagiarism as a separate product. Copyleaks bundles AI text detection in 30+ languages, AI image and deepfake scanning, cross-language plagiarism checks, LMS integrations, and a browser extension so one scan covers the formats students and marketers actually submit.

Teachers use it inside Canvas, Moodle, and Google Docs; editorial teams batch-scan websites via sitemap upload on Pro plans; enterprises route content through the API with role-based policies. Personal plans start at $16.99 per month with 100 unified credits, and Pro adds 25 seats with 1,000 credits monthly.
