StealthGPT vs StealthWriter

StealthWriter. Its free tier is permanent: 10 rewrites and 10 AI scans a day at 1,000 words per input, on the Ghost 5.2 Mini model, with no card mentioned, read 9 November 2026. Ten rewrites at 1,000 words is 10,000 words a day, which is more than Undetectable AI's 250-word trial and Walter Writes AI's 300 give in total, both checked on 8 November 2026.

StealthGPT's cheapest look costs $1.00 and a card. The pricing page reads "$1 for 3 days, then $29.99 per month" with a note marking it a limited trial offer, read 9 November 2026, so the trial is a discounted first three days of the Pro subscription, not a separate product. Its terms state that purchases are non-refundable and that cancellation takes effect at the end of the current paid term, read 9 November 2026.

Both read 9 November 2026. The free tier's catch is the model: StealthWriter's paid plans add Ghost 5.2 Pro and the Legacy models, so the free output is from a different model than the one a Starter buyer gets. StealthGPT's catch is the calendar.

The two sell capacity in different units, and the unit decides who pays less. StealthGPT sells words a month: 50,000 on Pro at $29.99, 200,000 on Max at $49.99, each request capped at 1,000 or 2,000 words, read 9 November 2026. StealthWriter sells rewrites a day: 50 on Starter at $20, 150 on Plus at $50, 350 on Pro at $100, each input up to 5,000 words, with no monthly word figure anywhere on the page, read 9 November 2026.

Figures read 9 November 2026. The pattern that favours StealthWriter is long pieces, steadily, because its request cap is five times StealthGPT's and its daily meter never runs out within a month. The pattern that favours StealthGPT is short pieces in bursts, because a monthly pool can be spent on one day and a daily quota cannot. Price is reported on this site and never scored.

StealthGPT's pricing page carries a logo strip headed with a claim to beat every AI detector, a banner for a new model it says beats Pangram and other detectors, and a FAQ answering yes to a question about Turnitin and GPTZero, all read 9 November 2026. Its terms back the marketing with a "Detected? Get your money back" policy whose proof is a screenshot from an accepted detector and whose exclusions include any result from Originality.ai, read 9 November 2026. StealthWriter's pricing page carries no success rate, no detector claim and no user count, read 9 November 2026, which is rare in this category.

This site repeats none of those claims as findings. Weber-Wulff and colleagues tested 14 AI text 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). Krishna and colleagues showed that a paraphrase model dropped DetectGPT's detection rate from 70.3 percent to 4.6 percent at a 1 percent false positive rate (Krishna et al. 2023, arXiv, read 9 November 2026). Paraphrasing moves detector readings; neither study says whether the rewrite kept the writer's claims.

The published method weights meaning kept at 35 points of 100, errors added at 20, detector pass rate at 30 and limits and access at 15, and runs each tool on its default and strongest documented setting, which for StealthWriter means Mini and Pro and for StealthGPT means whatever the interface shows on the run date. When a run is published, this page gains meaning, error and per-detector fields for both. Turnitin's detector is not available to the public, so no page here states a Turnitin result for either tool. No detector score should be the only evidence in a misconduct case.
