StealthGPT

StealthGPT is an AI detection remover tool that rewrites AI text so detectors score it as human. StealthGPT rewrites AI generated text so it reads as human and passes detectors such as Turnitin, GPTZero and Copyleaks.

StealthGPT is a text rewriting service built around one problem: AI detectors flag machine written prose because it repeats itself. The core Humanizer takes a block of AI generated text and rebuilds it sentence by sentence, keeping the arguments and facts intact while swapping the phrasing, rhythm and structure for something closer to how a person types. The company claims a 99 percent detection bypass rate across the major checkers, with public test results quoted against Turnitin, GPTZero, Copyleaks, Pangram, Originality.ai and others. Humanization also strips the invisible watermarks that Claude and Gemini embed in their output, so the rewritten text does not carry a machine origin marker. Around that engine sits a wider toolkit. Stealth Writer drafts original content rather than rewriting it, an SEO Writer targets search intent, and Stealth Agent runs a longer research, draft, fact check and humanize sequence in one pass. A free AI Detector and a watermark detector for ChatGPT, Claude and Gemini SynthID let you test output before sending it anywhere. Two rewrite depths exist: Stealth Lite cleans up obvious tells while staying close to the draft, and Super performs the fuller rewrite aimed at bypass. Tone presets range from Standard through High School and College to Ph.D so the register can follow the audience. In practice the workflow is paste, choose a model and tone, then humanize. Subscribers get a full text editor with formatting, extra generated paragraphs and in-text citations on higher tiers. Team accounts let subscribers invite colleagues at no extra cost, and enterprise runs handle up to 20,000 words per job by splitting long inputs and processing them in parallel. The obvious comparison set is the small crowd of bypass tools such as Undetectable AI, HIX Bypass and bypasser plugins. StealthGPT differentiates on breadth (detection, watermark removal, drafting and an API in one account) and on distribution through a Chrome extension with an auto typer, a WordPress plugin and an MCP connection for Claude, Cursor and n8n. The audience is students, content writers, agencies and businesses that generate at volume. It is a paid tool with a promotional trial, and the ethical question of passing machine text off as human is unresolved by design, so the buyer has to decide that part.
