What is Undetectable AI?
Undetectable AI combines AI-content detection with tools for rewriting and refining text. Users can paste writing or upload a file, check which sentences are flagged as potentially AI-generated, and use the humanizer to revise the wording. Its rewriting tools adjust sentence structure, vocabulary, and tone to make text read more naturally.
The toolkit also includes detectors for AI-generated images and audio, alongside paraphrasing and other writing tools. A Chrome extension brings detection and rewriting into browser-based workflows, including Google Docs and Gmail. The service supports more than 50 languages, with English as its primary focus.
Undetectable AI serves students, educators, professional writers, and businesses working with AI-assisted content. A 250-word free trial lets users test the service before activating a paid plan. Subscriptions offer word allowances and unlimited AI detection, while business arrangements include options for non-expiring credits, white labeling, and stricter data-retention controls.
