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 operator is a small sole business in India, 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

Operator is a small Indian business (Deceptioner Services) with little recourse for buyers abroad
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

Undetectable AI

Buy it only if you accept that passing a detector is a moving target: detector vendors retrain constantly, and text that cleared last month can flag next month. As a multi-format detection dashboard it is more defensible than as a bypass tool.

Pros

Detector and rewriter run in one pass, so you see which sentences changed and why
Coverage extends past text into image, voice, video and document classifiers
Browser extension works inside Docs and Gmail rather than a separate tab
Entry tier is genuinely cheap at annual rates

Cons

Rewrites often flatten voice and add filler to break statistical patterns
Detection on short passages is unreliable in both directions
Word quotas drain fast because rejected attempts still consume them
The free trial caps at 250 words, barely enough to judge output quality
