Humanize AI Text.Slip Past Detectors.
Paste AI-generated copy. We mix sentence cadence, strip the tell-tale phrases, and shift cadence so detectors like GPTZero, Originality and ZeroGPT lose confidence.

Pipeline pillars
What runs under the hood
Burstiness Restoration
GPT and Claude write at flatline rhythm. We restore natural variance: short punches next to long flowing thoughts — exactly how humans actually write.
Perplexity Lift
Detectors flag text whose word choices are too statistically predictable. Phrase-replacement swaps in less probable, more human alternatives without changing meaning.
Sentence Restructuring
AI loves a tidy subject-verb-object structure. We rewrite with subordinate clauses, fronted adverbials and parenthetical asides.
Contractions & Voice
Real writing breathes: don't, you'll, it's. Plus contextual voice shifts — formal where it matters, casual where it doesn't.
Multi-Layer Pipeline
Punctuation rebalancing, contraction injection, phrase replacement, sentence restructuring — applied in deterministic order, calibrated to your input.
Browser-First Privacy
Light mode runs entirely in your browser. Standard and Aggressive use our AI gateway with zero content storage.
How it runs
Three steps, mostly local
Paste text
Drop any AI-generated paragraph, essay or article into the editor — up to thousands of words at once.
Local rewrite
Five layers run in your browser. Typical: under one second per thousand words.
Human export
Copy the result or download it. Side-by-side diff shows exactly what changed and why.

FAQ
Common questions
Which detectors does this defeat?
GPTZero, Originality.ai, Turnitin, ZeroGPT, Copyleaks, Sapling, Winston AI. No tool guarantees 100% — detector models retrain weekly. Always review the output.
Will it change the meaning?
No. The pipeline preserves semantics — it swaps cadence, syntax and word choice, not the underlying argument. Run a quick read-through before publishing.
What's the difference between modes?
Light runs fully in-browser with deterministic rules. Standard and Aggressive use our AI gateway for deeper restructuring at higher credit cost.
Does it work on languages other than English?
Yes. The pipeline supports English and German out of the box, with auto-detection. More languages on the roadmap.
