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

01

Paste text

Drop any AI-generated paragraph, essay or article into the editor — up to thousands of words at once.

02

Local rewrite

Five layers run in your browser. Typical: under one second per thousand words.

03

Human export

Copy the result. 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.
