StealthGPT is an AI content "humanize" tool whose core goal is to rewrite AI-generated text into natural text that is not easily detected by AI detectors, while preserving the original meaning and readability as much as possible. According to the official introduction, its humanization engine can achieve an AI detection bypass rate of up to 99%, has more than 1.5 million users, and is used by more than 350 companies.
Main capabilities
- Text humanization: rewrites AI text at the sentence level, addressing signals that AI detectors focus on such as perplexity and burstiness, making the output read more like human writing.
- AI detector score estimation: estimates in the dashboard how mainstream detectors such as Turnitin and GPTZero will analyze the text.
- Long-form generation and humanization: the enterprise version raises the single-pass humanization limit to 20,000 words (previously 3,000 words); long inputs are split and processed in parallel, with real-time progress and one-click retry.
- Built-in AI detection: humanized text can be verified through the built-in detector to confirm the score before submission or publication.
- Tone options: offers tones such as Standard, High School, College, and Ph.D., imitating different writing styles.
- Writing tools: includes advanced writing tools, inline citations (available in some plans), automatic reference generation, SEO writing, chat with PDF, and more.
- Integration capabilities: can connect to 8,000+ apps via Zapier; provides a WordPress plugin; supports MCP clients such as Claude and Cursor; provides an n8n node; also has a Chrome extension and iPhone app.
- Team collaboration: Pro plans and above allow adding friends, colleagues, or classmates to a team, and it is said there is no extra charge.
- Credit rewards: subscription renewals earn 10 credits per month, and daily login earns 1 credit, which can be redeemed for gift cards from hundreds of major vendors.
How to use A typical workflow is: first generate content in AI writing tools such as ChatGPT, Claude, or Gemini, or directly use existing AI-generated text; copy the text and paste it into StealthGPT's humanization tool; run it to obtain the rewritten result; then verify the score through the built-in AI detector, and submit or publish after confirmation. The official statement says no manual editing or secondary processing is required. In addition, content can be generated or humanized directly in supported integrations, for example in WordPress to generate drafts, invoke it in Zapier Zaps, or automate processing in MCP clients and n8n workflows.
Applicable scenarios
- Students or educational scenarios: the official website mentions that you can register with a student email, enjoy a $0.99 plan for the first month, and mentions scenarios related to Turnitin detection.
- Content creators and SEO: provides SEO Writer, which can generate humanized SEO content containing keywords.
- Enterprises and teams: long-form humanization, team collaboration, API and workflow integration.
- Users who need research documents: can generate first drafts from topics, add real citations, automatically generate references, and support multiple academic citation formats.
Limitations and notes
- The official website clearly states: the bypass effect is based on independent tests and user reviews published as of mid-2026, and results will vary depending on detector version, content length, and the engine used; no tool can guarantee a 100% bypass, and detection models are updated regularly.
- Different subscription plans differ in features, word limits, citation permissions, etc. Specific prices and plan contents must be based on the official website's real-time pages; the official materials do not provide a complete price list.
- Humanization does not guarantee effectiveness across all detectors, all languages, and all content types, and users need to evaluate compliance and usage risks themselves.
