什么是 Undetectable AI？

Undetectable AI is a web-based AI detection and rewriting product centered on checking whether text will be flagged as machine-generated. The main detector lets users paste text, upload a file, or try sample content, and it presents results from multiple AI checkers at once.

The site also positions the product as a broader writing workflow tool, with an AI Humanizer, a Sentence Rewriter, a Word Counter, a Chrome Extension, and business offerings for white-label use, affiliate partnerships, and API-based integration. Pricing includes monthly and yearly plans, plus a business contact flow for custom needs.

Undetectable AI 能做什么？

AI text detection

Paste text, upload a file, or start from sample text to check whether content is likely to be flagged as AI-generated.

Collective detector results

See results from multiple major AI detectors at once instead of relying on a single checker.

Broad model coverage

The site says the detector recognizes content from ChatGPT, GPT-5, Gemini, Claude, Llama, DeepSeek, and paraphrased text.

Chrome extension

A browser extension is available for checking text while working in places like social media, email, and Google Docs.

Business and API options

Business pages describe white-label solutions, affiliate partnerships, and API access for organizations that want to embed the tools.

Rewrite and humanize tools

The AI Humanizer and Sentence Rewriter extend the workflow beyond detection to rewriting and humanization tasks.

使用场景

“Pre-publish content review”

Writers can run drafts through the detector before publishing to see whether the text is likely to trigger AI flags and then revise with the humanizer or sentence rewriter if needed.

“Academic integrity checks”

Students, teachers, and researchers can check essays, assignments, and research writing to understand whether content appears AI-generated before submission or review.

“SEO and content QA”

SEO teams and marketers can evaluate landing pages, articles, and product copy to reduce the chance that content looks machine-written.

“Team and product integration”

Businesses can add detection or humanization into their own services through white-label options, affiliate programs, or APIs.

“In-workflow checking”

People working in browsers can use the Chrome Extension to check text in emails, documents, and social posts without leaving the page.
