StealthGPT review: is it legit, and is it worth it?
StealthGPT is a legitimate paid AI writer and humanizer. Beyond a free 200-word detector scan, its pricing lists only paid plans, with a short trial offer for new users. It sells itself on detector scores and promises a refund if you're detected; we treat that as marketing, since no humanizer can guarantee a detector result.UpdatedWhat StealthGPT is
StealthGPT (stealthgpt.ai) does two jobs in one account. The AI humanizer rewrites text from ChatGPT, Claude, Gemini or any other model, and Stealth Writer and Stealth Agent generate new text: essays with citations, SEO articles and social posts. Around them sit an AI detector, a grammar checker, a summarizer, a watermark remover, Chat with PDF and Photo to Answers.It also has an iOS app, a Chrome extension, MCP access for Claude and Cursor, and an API on the Enterprise plan. Its pricing table lists more than 100 languages.How the humanizer works
You paste text and pick a model: Super, which StealthGPT describes as its "strongest bypass, full pipeline", or Lite, a faster rewrite for quick drafts. An optional quality check looks at similarity, facts, tone and hallucination risk, and paid plans can add Samurai, an add-on engine. StealthGPT says it rewrites "at the model level, addressing perplexity, burstiness, and every other signal AI detectors measure", then its built-in detector gives the result a human score.What it claims about detectors
StealthGPT's pitch is detector evasion, stated plainly. Its homepage says "We beat every AI Detector", its pricing FAQ says text "consistently scores as human on Turnitin, GPTZero, Originality.ai, and other major detectors", and its FAQ says subscriptions come with a money-back guarantee if you get detected.Those are StealthGPT's claims, and we haven't tested them. What a detector says depends on the text, its length and the detector's current version, and detectors such as Turnitin update their models over time. Read the guarantee's terms before counting on it. A refund also covers only the subscription: if your class bans AI-written work, a lower score doesn't make submitting it allowed.Is StealthGPT free?
Barely. The AI detector's standard scan is free for up to 200 words with no account, and a free account unlocks a deeper scan that shows which paragraphs or sentences pull the score down. For the humanizer and writer, the pricing page lists Pro and Max plans with weekly allowances (12,500 and 50,000 words a week) and per-request caps of 1,000 and 2,000 words, plus a short trial offer for new users. Enterprise adds monthly volume, longer inputs and API access. Check stealthgpt.ai/pricing for current prices.Where it's strong
- Writing and humanizing under one subscription, with citations in the essay writer.
- Two humanizer models and an optional check for facts and hallucinations.
- It works in Chrome, on iPhone, and inside Claude or Cursor through MCP.
- A free detector scan without an account.
Where it falls short
- Little to try for free: the detector's free scan stops at 200 words.
- Its claims, such as beating every detector, promise more than any humanizer can deliver for every text.
- Generating essays and making them harder to detect is the main use it advertises, which puts students at risk where AI-written work is banned.
- API access only on Enterprise.
Who it's for
StealthGPT fits people who want an AI writer and a humanizer under one login and will use the extension and MCP tools. If you already draft in ChatGPT or Claude and only want to clean up the result, you'd be paying for a writer you don't need.Leap's free humanizer, for a lighter pass
Leap doesn't generate text. Our humanizer is a free cleanup pass for a draft you already have, and it runs in your browser with no sign-up and no word limit. It removes stock AI phrases, swaps words like "utilize" for plain ones, turns em dashes into commas, strips invisible characters, adds contractions and lists sentences of nearly the same length so you can vary them.It keeps your wording and makes no promise about any detector. Clean up a draft below and check it with the free AI detector, which scores every sentence. Rewrite, under the result, is an optional paid full rewrite; your text leaves the page only if you press it.The cleanup runs in your browser and fixes common AI writing habits. It does not guarantee that the text passes any AI detector.
Verdict
StealthGPT is a legitimate, well-stocked product built around one promise: that its text won't be detected. If that's why you'd buy it, know that no tool can guarantee it and that a refund doesn't undo a misconduct case. If you want an AI writer with a humanizer attached and your rules allow it, it covers a lot in one account.Frequently asked questions
