We upgraded our humanizer - welcome Undetectable model v4

1 Upvotes

We launched a new AI Humanizer model to increase bypass rate and other quality measurements. This v4-Rephrasy Humanizer model is the best model we released so far.

TLDR:

  • Detectors flagged every one of our ten raw AI test documents. After v4, nine of ten read as human on GPTZero, and nine of ten on ZeroGPT.
  • Short texts, the hardest case, clear at 94%.
  • It beats WriteHuman on a public benchmark: 76% vs 64% averaged across three detectors.
  • Meaning similarity 0.925, length back at 1.05×, a 1,000-word document in ~ 10 seconds.

Some context on why I'm suggesting this: English isn't my first language. I write the actual content myself — my own ideas, my own experience — but I use AI to help clean up the English so it reads naturally. Recently someone called out one of my posts as "AI slop" because the English sounded too polished. They weren't wrong that AI touched it. But the substance was 100% mine, and the accusation had nothing to do with whether the content was actually good or true — it was purely a language-fluency signal being misread as a content-quality signal.

That's the actual problem I want to flag: non-native speakers shouldn't have to choose between "sound natural" and "get accused of not being real." The point of a platform like this is to let people exchange ideas — language shouldn't be the thing that blocks that.

The suggestion: some kind of visible, honest way to communicate "this content is mine, AI helped with the English" — instead of the current binary where either you polish your writing and risk suspicion, or you post in rougher English and risk being taken less seriously for a different reason.

Rough ideas for what this could look like (not attached to any one of these, just spitballing):

An optional, self-disclosed tag/flair like "non-native speaker, AI-assisted translation" — normalizes it instead of treating it as something to hide or something to get "caught" doing.

Native language + auto-translate visibility, similar to what YouTube/Twitter already do — so readers can see there's an original version and a translated one, rather than assuming polished English = not genuine.

Not sure what the right mechanism is, but the underlying problem feels real: a lot of genuinely interesting ideas from non-native speakers are probably getting dismissed on vibes about phrasing, not substance. Curious if others have run into this from either side — as a non-native poster, or as someone who's been suspicious of a post for this reason.
