AI or Not vs AI Detector By Custom Writings

AI or Not is an AI detection platform that checks whether images, text, audio, music, and video were created by humans or generated by AI. You can upload files directly on the site or integrate detection through a REST API. The service identifies specific generators like Stable Diffusion and Midjourney for images, flags deepfakes in faces and video, and scores text for AI authorship.

The platform reports 98.9% accuracy across modalities and has processed over 6 million checks for more than 500,000 users. Customers include media and enterprise teams that need to verify content authenticity, combat misinformation, and meet emerging AI labeling requirements.

Developers get API keys on every plan, including the free tier. Credits roll over monthly on paid plans, and per-modality pricing covers image, text, voice, music, video, deepfake, and reverse image search checks.

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.
