StealthWriter
High-Accuracy Evasion
StealthWriter is built for one job above all: getting AI text past a detector, even when that means trading a little polish for it. Its edge is a dual-model system — Ninja for light, everyday rewriting, and Ghost for maximum evasion. Ghost doesn't just swap words; it restructures sentences wholesale, introducing the kind of uneven, "calculated chaos" that reads as authentically human to an algorithm. A free Ninja tier lets you try the basics, and an interactive sentence-alternatives tool lets you smooth any rough spots the aggressive rewrite leaves behind. For SEO specialists and content teams who need volume to pass, it's a purpose-built workhorse.
Two models, two jobs
The dual-model design is the whole idea. Ninja handles light rewriting — quick, simple, and free up to a daily limit — while Ghost is the heavy hitter, completely rebuilding sentence structure to break the statistical patterns detectors look for. That aggression is what makes Ghost effective, and it comes with an honest trade: occasionally it produces a phrase that reads a little off. StealthWriter builds the fix right in — click any sentence and get five alternative phrasings to pick from, so you keep the evasion and tidy the readability in the same pass. A built-in detector scores your text before and after, and a content generator can draft from scratch while holding your SEO keywords in place.

How it holds up
StealthWriter's approach is deliberately aggressive, and that's the source of both its strength and its one quirk. By restructuring sentences rather than swapping synonyms, Ghost breaks the patterns detectors are trained on, which is exactly why it's favored for high-volume work where passing is the priority. The honest flip side is readability: the harder the rewrite, the more likely a sentence comes out slightly awkward — which is precisely why the click-for-alternatives tool exists, and why it's worth using as part of the workflow rather than skipping. Run a piece through Ghost, scan it with the built-in detector, and clean up any rough sentences with the alternatives picker, and you get evasion-first output that still reads fine.
Built for volume and SEO
StealthWriter knows its audience. The SEO specialist running content at scale gets a tool tuned for throughput, where "good enough and passing" beats slow perfection. The content agency processing client articles can clear a batch in a fraction of the manual time. And the keyword-preserving generator means brand and target terms survive both the rewrite and a from-scratch draft. It's a commodity-content workhorse, and it's honest about being one.
The verdict
For the SEO specialist and the high-volume content team — anyone who needs AI text to clear a detector at pace and can spend a moment tidying the occasional rough sentence — StealthWriter is a focused, effective pick. Ghost is the model that does the heavy lifting; the free Ninja tier is the easy way to get a feel for it first. It's less suited to someone who wants flawless prose in a single click, since the aggressive evasion trades a little polish for results. Start with Ghost, lean on the sentence-alternatives tool, and you've got a dependable evasion-first workflow.
