Refrazr vs StealthWriter (2026): Two Tools, Two Completely Different Price Models

StealthWriter charges for humanizations per day starting at $20/mo; Refrazr charges for words starting at $1.99. A fact-checked comparison of pricing, limits, features and what neither tool can promise you.

Most comparisons between these two tools get stuck arguing about which one "works better" — a question neither company can honestly answer for you. The more useful difference is duller and much easier to check: StealthWriter and Refrazr charge for completely different things. One sells you a rate — how many times per day you get to press the button. The other sells you a quantity — how many words you get to rewrite. Once you see which of those matches how you actually write, the pricing question mostly answers itself, and the gap for a typical user is around ten times.

The short version: StealthWriter meters humanizations per day and starts at $20/mo, with a free tier of 10 rewrites a day capped at 1,000 words per paste. Refrazr meters words, starts at $1.99 for a word pack that never expires, and gives 500 words a day free with no account. StealthWriter has two features Refrazr genuinely does not: sentence-level alternative rewrites and three rewrite intensity levels. Neither tool can promise you a detector result, and any comparison that claims otherwise is selling something.

The thing nobody compares: what you're actually buying

StealthWriter's plans are built around a daily action count. The free tier gives you 10 humanizations a day and 10 AI scans a day, with any single paste capped at 1,000 words. Starter, at $20/mo, raises that to 50 humanizations a day and lifts the per-paste ceiling to 5,000 words. Plus ($50/mo) gives 150 a day, Pro ($100/mo) gives 350 a day, and a Scale tier sits at $400/mo. Every paid tier shares the same 5,000-word paste limit — what you're buying as you climb is frequency, not size.

Refrazr's plans are built around words. The free tier is 500 words a day, spread across up to three rewrites, and it needs no account at all — you land on the page and use it. Beyond that there are word packs that don't expire: 3,000 words for $1.99, 10,000 for $3.99, 30,000 for $7.99. Buy once, use whenever. Pro is $6.99/mo for unlimited words if you'd rather not think about it. There's no per-paste word ceiling worth mentioning on the site; the request body caps out around 100,000 characters, so what actually constrains you is your allowance, not the size of what you paste.

This is why the two products feel so different in practice even though they do a similar job. Someone rewriting fifty short product blurbs a day is a bad fit for a word budget and a great fit for a daily action count. Someone with one 2,000-word essay a month is the exact opposite: on StealthWriter's free tier they have to split it into two pastes, and on Starter they're paying $20/mo for 49 daily humanizations they will never touch.

What it costs for real use

Take three honest scenarios and run the numbers.

How you actually use itStealthWriterRefrazr
One 2,000-word essay a month Free tier works if you split it into two pastes (1,000-word cap) $1.99 word pack covers it for about a month and a half; free tier needs four days of splitting
~10,000 words a month, in chunks $20/mo Starter $3.99, once — the pack doesn't expire
High volume, many separate short pieces daily $50–100/mo depending on daily count $6.99/mo Pro, unlimited words

The middle row is the one worth sitting with. Ten thousand words is a normal month for a freelance writer or a student in a heavy term. On one tool that's a $20 recurring charge; on the other it's a single $3.99 payment that keeps working next month. That is not a small difference dressed up in marketing — it's the same job priced on a different axis.

The bottom row flips less than you'd think, because Refrazr's Pro tier doesn't meter words at all. Where StealthWriter's answer to "I need a lot" is a higher daily count at $50 or $100, Refrazr's answer is $6.99 and no counter. If you genuinely need hundreds of separate rewrites a day, though, check the fit yourself rather than taking either company's word for it.

What StealthWriter does that Refrazr doesn't

Two things, and both are real.

Sentence-level alternative rewrites. StealthWriter lets you click an individual sentence in the output and cycle through other versions of it. That's a good interaction for anyone who wants the rewrite mostly as-is but dislikes one specific line. Refrazr gives you one output and expects you to edit it yourself. If you like working sentence by sentence, that's a point for them and there's no honest way around it.

Rewrite intensity levels. StealthWriter offers light, medium, and aggressive rewriting. Refrazr has four style presets — casual, academic, professional, blog — which is a different axis entirely: we let you pick a register, not a depth. Wanting "the same voice but changed less" is a reasonable thing to want, and Refrazr currently has no control for it.

StealthWriter also ships a detector with a sentence-by-sentence deep scan. Refrazr scores your input text as a whole before you rewrite it. Theirs is the more granular tool of the two.

Where Refrazr comes out ahead

You can try it without an account. 500 words a day, no email, no signup wall. StealthWriter's free tier requires registering first. For a one-time "does this even help my paragraph" test, that difference decides whether most people ever find out.

Nothing expires. A word pack sits in your account until you use it. Subscriptions are the opposite by design — the month passes whether you wrote anything or not, and writing is famously bursty.

There's an API and an MCP server. If you want rewriting inside your own pipeline, or inside an AI assistant that speaks MCP, that exists. StealthWriter's site doesn't state whether it offers an API.

We publish the method, including the part where we were wrong. The methodology page lays out how the rewrite works, and it's less flattering than a marketing page would be. An earlier version of Refrazr scored your draft against a checklist of AI fingerprints and then swept the output with a battery of cleanup rules. In July 2026 we put that pipeline in front of a strict reading judge and it lost — the mechanical fixes were themselves the most machine-like thing in the text. Most of that code is deleted. What runs now is a single pass: the whole draft goes to the model under one instruction to write it the way a sharp person actually would, plus one rule that doesn't bend — every name, number, date and claim from your source survives untouched.

On the detector question, plainly

StealthWriter's own homepage describes the product as rewriting AI-generated content "so it reads naturally human, polished, and ready to use." That's a reasonable, defensible claim — much the same position Grammarly takes with its own humanizer. Much of the third-party writing about the tool is considerably less careful, and you'll find review sites promising specific detector outcomes.

Refrazr doesn't make those promises, and the reason is worth stating: nobody controls somebody else's classifier. Detectors retrain, thresholds move, and a percentage that held last month means nothing about tomorrow. The US Federal Trade Commission has already acted against an AI-detection company over unsubstantiated accuracy claims, which is a decent signal about where that kind of marketing leads. We removed every bypass claim from this site for exactly that reason. If a comparison page tells you a tool passes a named detector at a named rate, treat the number as advertising, not measurement.

The honest version: both tools rewrite text so it reads more like a person wrote it. What any given detector does with the result varies by text, by detector, and by model version, and the only way to know is to run your own material through both free tiers and read the output yourself.

Which one to pick

Pick StealthWriter if you rewrite constantly in short bursts, want to nudge individual sentences, or want a dial for how hard the rewrite pushes. Those are its strengths and a word-based competitor doesn't beat them by being cheaper.

Pick Refrazr if your writing comes in occasional lumps rather than a daily stream, if you'd rather pay once than subscribe, if you want to test something before handing over an email address, or if you want the tool inside your own code. And if you're comparing on price at ordinary volumes, the gap is roughly ten to one.

Both have free tiers. Run the same paragraph through both and read the two outputs next to your original. Fifteen minutes of that will tell you more than any comparison page, including this one.

Frequently asked

Is Refrazr cheaper than StealthWriter?
At ordinary volumes, yes, by a wide margin. StealthWriter's cheapest paid plan is $20/mo. Refrazr's word packs start at $1.99 for 3,000 words and don't expire, and unlimited Pro is $6.99/mo. For a typical 10,000-word month that's $20 recurring versus $3.99 once. The comparison narrows only if you need hundreds of separate rewrites every day, which is the shape StealthWriter's pricing is built for.
What does StealthWriter cost in 2026?
Free ($0) gives 10 humanizations and 10 AI scans a day with a 1,000-word cap per paste. Starter is $20/mo for 50 humanizations a day, Plus is $50/mo for 150, and Pro is $100/mo for 350. All three paid tiers allow 5,000 words per paste. A Scale tier is listed at $400/mo. Prices checked against StealthWriter's own site in August 2026.
Can I use either tool without creating an account?
Refrazr, yes — 500 words a day with no signup at all. StealthWriter's free tier requires registration before you can use it. If you just want to test one paragraph before committing anything, that's a practical difference.
Does StealthWriter do anything Refrazr cannot?
Two things, both real. It lets you click a single sentence in the output and cycle through alternative versions of it, and it offers light, medium and aggressive rewrite intensity levels. Refrazr gives you one output with four style presets — casual, academic, professional, blog — which controls register rather than depth. If sentence-level control matters to you, StealthWriter does something Refrazr does not.
Which one gets past AI detectors?
Neither company can honestly answer that, and Refrazr doesn't try. Detectors retrain constantly, thresholds shift, and no tool controls another company's classifier — the FTC has already acted against an AI-detection firm over unsubstantiated accuracy claims. Both tools rewrite text to read more naturally; what a specific detector does with the result varies by text, detector and model version. Run your own material through both free tiers and judge the output you can actually see.
Do Refrazr word packs expire?
No. A pack sits in your account until you use it, which is the main structural difference from a subscription. Writing tends to come in bursts, and a subscription charges you for the quiet months too. Pro at $6.99/mo exists for people who'd rather have unlimited words than track a balance.
Does either tool offer an API?
Refrazr does, along with an MCP server if you want rewriting available inside an AI assistant that speaks the protocol. StealthWriter's site doesn't state whether an API is available, so check with them directly if that's a requirement.
