StealthWriter
StealthWriter humanizes AI-generated text and scans it with a built-in V1/V2 AI detector — all in one browser tab.
StealthWriter's edge is the humanize-then-verify loop in one tab: a V1/V2 detector with sentence-level highlights means you can see what still needs work instead of hoping. The free plan at 10 humanizations and 10 AI scans per day is enough to judge whether the output holds up on your own writing. Worth paying for if you push volume — Starter at $20/mo or $200/year billed annually gets you Ghost 5.2 Pro, 50 humanizations a day, and 5,000 words per input. The ceiling is 5,000 words per input even on Scale ($400/mo or $4,000/year billed annually), so very long documents have to be chunked. If your need is general rewriting rather than AI evasion, QuillBot covers more ground.

Skip StealthWriter if you routinely process documents longer than 5,000 words in one pass at a time, since that per-input cap holds on every published tier including Scale at $400/mo billed annually.
The 5,000-words-per-input ceiling applies on every tier, so processing a 20,000-word manuscript means four separate passes and four of your daily humanizations.
StealthWriter's ladder is unusually granular for a humanizer: Free at $0, then Starter $20/mo or $200/year billed annually, Plus $50/mo or $500/year, Pro $100/mo or $1,000/year, Business $200/mo, and Scale $400/mo or $4,000/year, with Enterprise quoted custom. The $20 Starter tier sits in the same range as general-purpose rewriters like QuillBot Premium, but StealthWriter charges for daily humanization volume rather than a flat feature unlock — so light users pay the same as heavy ones until

About StealthWriter
StealthWriter is a browser-based AI humanizer for text that reads too obviously machine-made. You paste a draft from ChatGPT, Claude, Gemini, or any other model, choose a rewrite level (light, medium, or aggressive), and it returns natural-sounding prose — the vendor claims under 10 seconds. What sets it apart from a plain paraphraser is the loop: the built-in V1/V2 detector runs on your text before and after, showing a human score with sentence-level color-coded highlights so you can see which lines still look synthetic. Deep Scan adds per-sentence analysis, and clicking any sentence surfaces alternative rewrites if a line lands wrong. On the model side, Ghost 5.2 Mini is the default lightweight rewrite model on the free plan, while Ghost 5.2 Pro (tuned for stronger coherence and readability) and legacy Ghost 5.1 / Ghost 4.6 models unlock on paid plans. The 5.1 model supports major world languages including German, Spanish, Portuguese, French, Italian, Dutch, Chinese, and Japanese. StealthWriter states submitted text is not stored or used for training. Pricing runs from a $0 free plan (10 humanizations and 10 AI scans per day, 1,000 words per input) through Starter ($20/mo or $200/year), Plus ($50/mo or $500/year), Pro ($100/mo or $1,000/year), Business ($200/mo), and Scale ($400/mo or $4,000/year), with an Enterprise tier quoted for custom daily volume. It is narrower than all-purpose rewriters like QuillBot, but it keeps the detection check inside the same window — useful when you want to verify before you submit rather than guess.
Behind the Verdict
StealthWriter does one job and does it in a tight loop. You paste text, it rewrites with one of three levels, and the same screen runs an AI detector so you can see the before and after human score with sentence-level color highlights. That combination is the real product: a paraphraser tells you it changed the words; StealthWriter tells you which sentences still look machine-made. Deep Scan pushes that further with per-sentence analysis, and clicking a sentence surfaces alternative rewrites, so you can fix a single line without regenerating the whole draft. The model lineup is explicit: Ghost 5.2 Mini is the default lightweight model on the free plan, Ghost 5.2 Pro adds stronger coherence and readability and unlocks on paid plans, and legacy Ghost 5.1 and Ghost 4.6 remain selectable. Ghost 5.1 brought major-language support — German, Spanish, Portuguese, French, Italian, Dutch, Chinese, Japanese — so non-English writers are not forced through English first. On data handling the company states clearly that submitted text is not stored after processing, not shared with third parties, and not used for training. Where it fits: individual writers, marketers, bloggers, researchers, and freelancers who draft with ChatGPT, Claude, or Gemini and want the final read to sound like a person. The daily-limit ladder (10 free, 50 Starter, 150 Plus, 350 Pro, 800 Business, 2,000 Scale, custom Enterprise) maps cleanly onto light creators through to agencies, and the top self-serve tiers exist so teams do not have to negotiate just to get volume. Where it does not: the 5,000-words-per-input ceiling applies even on Scale, so books, long reports, and big contracts have to be processed in pieces. There is no app to install beyond the browser, and collaboration is not the product — the highest tiers add volume and priority support, not shared workspaces or role management. If your process is general rewriting, summarization, or grammar checking across formats, a broader tool such as QuillBot covers more ground. StealthWriter is narrow on purpose: it is the tool you reach for when the draft is done and the only remaining question is whether it reads human.

Real-world workflow fit
Concrete scenarios for the personas StealthWriter actually fits — and what changes day-one when you adopt it.
Draft the post in ChatGPT, paste it into StealthWriter, pick the medium rewrite level, then run the V2 detector on the result and click any sentence that still shows as synthetic to try an alternative rewrite.
Outcome: Deliverable reads naturally on the first client read-through, and you have a human-score screenshot to show if the client asks whether AI was used.
Paste an AI-assisted essay section into the no-account scanner (under 500 words) to see the baseline human score, then sign in on the Free plan and humanize the section with Ghost 5.2 Mini, reviewing Deep Scan highlights per sentence.
Outcome: You leave with text you have actually read line by line and a clear view of which passages were still flagged, without paying anything.
Team members run client drafts through the 800 humanizations/day allowance on Business, using Ghost 5.2 Pro for coherence, and switch to the 5.1 model for German, Spanish, and Portuguese client work.
Outcome: Multi-language client deliverables ship in one workflow, and volume stays inside the 800/day cap instead of requiring Enterprise procurement.
Use Cases

- Improve readability of AI-assisted research summaries using Deep Scan highlights
- Humanize content in German, Spanish, Portuguese, French, Italian, Dutch, Chinese, or Japanese

Models Under the Hood
as of 2026-09-24
Limitations
- The free plan caps you at 10 humanizations and 10 AI scans per day with 1,000 words per input.
- Paid tiers raise the daily ceiling (50, 150, 350, 800, 2,000, or custom on Enterprise) but every published tier tops out at 5,000 words per input, so long documents have to be processed in chunks.
- The product is web-only; the evidence makes no mention of a desktop or mobile app.
- Collaboration is not part of the offering — the higher self-serve tiers add volume and priority support, not shared workspaces or roles.

Where the pricing makes sense
The company stage and team size where StealthWriter's pricing actually pencils out — and where peers do it cheaper.
StealthWriter's ladder is unusually granular for a humanizer: Free at $0, then Starter $20/mo or $200/year billed annually, Plus $50/mo or $500/year, Pro $100/mo or $1,000/year, Business $200/mo, and Scale $400/mo or $4,000/year, with Enterprise quoted custom. The $20 Starter tier sits in the same range as general-purpose rewriters like QuillBot Premium, but StealthWriter charges for daily humanization volume rather than a flat feature unlock — so light users pay the same as heavy ones until
Setup time & first value
How long it actually takes to get something useful out of StealthWriter — broken out by persona, not the marketing-page minute.
Free-tier users can paste text into the no-account scanner (up to 500 words) in under a minute to see a human score; signing up for the Free plan takes another minute or two before the first humanization. Paid tiers add nothing to setup — upgrading only raises daily limits and unlocks Ghost 5.2 Pro, and the dashboard Billing page handles invoices and subscription changes without support contact.
Switching to or from StealthWriter
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From QuillBot: paste your drafts into StealthWriter and use the V1/V2 detector to see the human score, since QuillBot's paraphrase mode does not report that.
- ↗To QuillBot: move if what you actually need is general paraphrasing, summarization, or grammar checking rather than AI-evasion detection on every draft.

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 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. Choose Surfer AI if you need Google- and AI-search-optimized articles that rank, complete with keyword data, competitor analysis, and auto-linking. They serve different workflows: StealthWriter humanizes existing content; Surfer AI produces original SEO content from scratch.
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.
