StealthWriter
AI text humanizer with built-in detector that rewrites ChatGPT, Claude & Gemini writing to bypass detection.
Buyers who need verifiable results, not just a rewrite, will appreciate the built-in V2 detector with sentence-level feedback. The free tier is surprisingly generous for casual use, but the lack of API access rules out automation-heavy workflows. If you're doing manual, quick humanization with transparency, StealthWriter is a dependable pick.

Skip StealthWriter if you need API access for automation, team collaboration features, or plan to humanize content longer than 5,000 words per input.
Going past the daily humanization limit requires upgrading to a higher tier, which can jump from $50/mo to $100/mo or more.
StealthWriter's pricing fits individuals and small teams who need manual, low-volume humanization with a built-in detector. The free plan is generous (10/day), but if you need higher volume, the per-day costs add up — Pro at $100/mo for 350/day is pricier than QuillBot's unlimited plan. For automation-heavy workflows, you'd be better off with a developer-focused API service like Undetectable AI.

About StealthWriter
StealthWriter is an AI text humanizer and detector that rewrites AI-generated content so it reads naturally human. It handles drafts from ChatGPT, Claude, or Gemini, offering light, medium, or aggressive rewrite levels. You can fine-tune any sentence by clicking to see alternative rewrites. The built-in V2 AI detector scans your text before and after humanizing, giving sentence-level color-coded highlights and confidence scores so you know exactly where you stand. This verification loop — see the score, adjust, rescan — sets it apart from other humanizers that leave you guessing. The latest Ghost 5.2 Mini model is the default lightweight option, while Ghost 5.2 Pro offers stronger coherence and readability. StealthWriter is designed for students, bloggers, marketers, copywriters, researchers, and professionals who rely on AI assistance but need the final product to pass as human-written. The free plan includes 10 humanizations and 10 AI scans per day with 1,000 words per input, no credit card required. Paid tiers like Starter ($20/mo) and Pro ($100/mo) bump daily volume up to 350 humanizations. Processing happens in seconds, and your text is not stored or shared with third parties — a privacy detail many competitors don't match. In a crowded humanizer market, StealthWriter leans on two things: a detector that actually works (fewer false positives than older V1 scanning) and a clean, fast user experience without the awkward phrasing some competitors introduce.
Behind the Verdict
StealthWriter is a solid choice if you're looking to humanize AI-generated text with a built-in verification loop. The standout feature is the V2 AI detector, which gives you a confidence score and sentence-level color-coded highlights before and after humanizing. This removes the guesswork — you can see exactly what might be flagged and adjust. The rewrite quality is generally good, especially with the Ghost 5.2 models, and you can fine-tune any sentence with alternative rewrites. The free plan is generous for casual use (10 humanizations/day), and paid plans scale up to 2,000 humanizations/day on the Scale tier. However, there's no API access, no collaboration features, and no mobile apps — so this is for manual, single-user workflows. If you need automation or team features, you'd be better off with a tool like Undetectable AI or QuillBot, though those don't offer the same detector transparency. Privacy is a plus: your text isn't stored or shared, which is rare. Overall, StealthWriter is a dependable pick for students, bloggers, and professionals who want fast, verifiable humanization, but it's not for teams or high-volume automation.

Featured Head-to-Head Comparisons
Stealthwriter vs Writer
Choose StealthWriter if your priority is bypassing AI detectors cost-effectively — its Ghost 5.2 models offer industry-leading humanization with sentence-level feedback. Choose Writer if you're an enterprise needing brand-controlled, agentic workflows at scale, even though it lacks humanization for detection evasion. For most individual users, StealthWriter's simpler freemium wins; for organizations with compliance, Writer's platform justifies the price.
Stealthwriter vs Letterhead
If your primary need is humanizing AI-generated text to evade detection (with built-in detection analysis), StealthWriter is the clear choice with transparent freemium pricing. If you run a newsletter team managing multiple brands and need AI-driven workflow automation, portfolio analytics, and revenue management, Letterhead is purpose-built for that – but requires a sales call and is aimed at enterprises only. They solve completely different problems; pick the tool that matches your core use case.
Stealthwriter vs Surfer Ai
Choose StealthWriter if your priority is making AI-generated text sound human to bypass detectors like Turnitin or GPTZero, with fast, sentence-level control.
