What StealthGPT is

StealthGPT combines an AI text humanizer, writing tools, and an AI detector. Its Stealth Writer creates essays and other text with in-text citations and bibliography formatting. Stealth Agent brings web research, drafting, relevant fact-checking, and humanization into one workflow. The detector estimates how major detectors such as Turnitin analyze text; the home page also offers a detector that can be used without signing up.

The service supports 100+ languages across its plans. Listed integrations include Claude, Cursor, n8n, WordPress, and Zapier, with MCP access for compatible tools. Its REST API includes Writer and Humanizer, Stealth Agent, and usage-and-balance endpoints. The pricing FAQ says user content is not shared with detectors or third parties and that generated content stays in the user’s account. The privacy policy notes that security for internet transmission or storage cannot be guaranteed. A free plan and free trial are available. Paid options include pay-as-you-go Super at $0.05 per 100 words and Developer API usage at $0.20 per 1K words; the Enterprise plan is $179.99 a month.
