Walter Writes AI vs StealthWriter

The free tiers are different kinds of thing. Walter's is a trial: 300 words once, with no card, and then a purchase. StealthWriter's is a tier: 10 rewrites a day at 1,000 words each, every day, with no card mentioned on the page, read 9 November 2026. For a reader deciding whether to use a humanizer at all, one shows a paragraph and the other shows a week's work.

Walter trial size checked on 8 November 2026; StealthWriter figures read on its pricing page on 9 November 2026. The site's free ranking, the best free AI humanizer list, orders tools by how much text a free limit accepts whole, and the two tools sit at opposite ends of it. One thing to carry from the free tier to the paid one: StealthWriter's free model is Ghost 5.2 Mini, and every paid plan adds Ghost 5.2 Pro, so the free output is not the paid output.

Walter Writes AI sells words. Starter gives 30,000 a month at 750 per request for $8 a month billed $96 yearly; Pro gives 70,000 at 1,500 per request for $13 billed $156; Elite 200,000 at 2,000 for $26 billed $312, read on the homepage pricing block on 9 November 2026. StealthWriter sells rewrites a day: Starter 50, Plus 150, Pro 350, Business 800 and Scale 2,000, at $20, $50, $100, $200 and $400 a month, each at 5,000 words per input, read on its pricing page the same day. StealthWriter's page states no monthly word figure anywhere.

Walter figures read 9 November 2026; StealthWriter figures read 9 November 2026. The pattern the table shows is plain. A writer who works steadily, every day, in long pieces gets more from a daily meter; a writer who works in bursts, or in short pieces, gets more from a monthly pool. The yearly cost runs the other way at low volume: Walter's $96 a year is less than half of StealthWriter's $240 at list price. Price is reported on this site and never scored.

Walter Writes AI names three modes, Simple, Standard and Enhanced, described as a range from subtle to advanced, read on its homepage on 9 November 2026. StealthWriter offers models rather than modes: Ghost 5.2 Mini on the free tier, and Ghost 5.2 Pro plus the Ghost Legacy models on any paid plan, read on its pricing page the same day, with no description of how Pro differs from Mini beyond the name. A named strength ladder is a control a writer can use on every paste; a model picker is a control a buyer uses once, by paying.

The published method runs each tool on its default setting and on its strongest documented mode as a second row. For Walter that means two of its three modes; for StealthWriter it means Mini and Pro, with the free tier's model standing in as the default where the 1,000-word cap accepts the input, which it does for every input in the protocol's 350 to 500 word range.

No peer-reviewed study has tested either product by name in a way this site could cite, so the research here is about the category. Weber-Wulff and colleagues tested 14 detectors and found every one below 80 percent accuracy, with accuracy falling further on paraphrased and machine-translated text (Weber-Wulff et al. 2023, International Journal for Educational Integrity, read 9 November 2026). GPTZero, one of the five detectors in the site's panel, states that its model shields against common evasion methods including paraphrasing and that it keeps its false positive rate at no more than 1 percent when evaluating AI against human text (GPTZero technology page, read 9 November 2026).

Both vendors bundle a detector of their own. Walter Writes AI returns what it calls an authenticity score after each rewrite, read 9 November 2026; StealthWriter lists an AI detector in two versions and a deep scan on every tier, read the same day. A vendor's detector reading its own output is not independent evidence, and neither reading appears as a finding on this site. StealthWriter's pricing page carries no success rate, no pass figure and no user count, which is rare in this category and is noted as a fact rather than a merit.

Those sources measure detector readings, not whether the rewritten text kept the writer's claims. The method on this site weights meaning kept at 35 points of 100, errors introduced at 20, detector pass rate at 30 and limits and access at 15, and two editors rate every output blind. When a run is published, this page gains meaning, error and per-detector fields for both tools. No detector score should be the only evidence in a misconduct case.
