What our research says

DecEptioner

A detector-evasion rewriter with an unusually plain pitch: it names the detectors it aims to beat and prices word volume in tiers from $10 a month. The free tier is enough to test whether the output survives your own detector. The real problems are not technical — the vendor is anonymous, detector evasion breaks most schools' academic-integrity rules, and every detector update can invalidate the whole product overnight.

Pros

  • Free tier of 1500 rewriter words needs no card and shows the output quality up front
  • Word allowances and per-request caps are stated plainly for every tier
  • Chrome extension in addition to the web app, with 30-day rewrite history on all plans
  • API access included on Premium and on any annual plan

Cons

  • No company, founder or country is named anywhere on the site
  • Detector evasion is a moving target — any detector update can reset the claim
  • API is withheld from monthly Basic and Standard subscribers
  • The free tier caps a single rewrite at 400 words, too short for most documents

StealthWriter

Pairing the rewriter with its own detector in one screen is the sensible design choice here — you can see the before and after score instead of pasting into a third tool to find out. The tiering is honest about what you are buying: daily rewrite count and input length, nothing hidden. Everything else about this category applies, though: detector scores are not a guarantee, the rewrite flattens voice and sometimes meaning, and using it on assessed work is a disciplinary matter regardless of what the score says.

Pros

  • Built-in detector scores text before and after the rewrite in the same interface
  • Free tier is a standing 10 rewrites a day, not a one-off trial
  • Every paid tier raises input length to 5,000 words, so tiers differ only by volume
  • Named US operator with published phone and email support hours
  • Changelog actively maintained, indicating ongoing development

Cons

  • Detector evasion degrades as detectors update — today's score is not a durable result
  • Rewriting flattens voice and can quietly alter facts or technical terms
  • $400/month top tier is steep for a single-function tool, and there is no API to justify it
  • Free tier's 1,000-word input cap excludes most real articles

Which one fits

Choose DecEptioner if you need

  • Writers whose genuinely human drafts keep getting false-flagged by a detector
  • Testing how brittle a given AI detector actually is
  • Bulk rewriting where per-word cost matters more than style

Choose StealthWriter if you need

  • Editing model-drafted marketing copy so it reads less mechanically
  • Checking a draft's detector score before it goes to a client who screens for AI text
  • Non-native writers polishing model-assisted drafts for tone
