Make AI-generated text read like you wrote it.

NaturalOutput rewrites AI-generated prose so its stylometric signal moves toward human-written text. Detection runs inside the loop as our internal compass — never the product we sell.

Built for quality and speed

Stylometric signals, detector-in-loop verification, and a hardened security pipeline — engineered to produce prose that reads as human-written.

Stylometric Rewriting

24 stylometric signals — sentence variability, vocabulary diversity, burstiness, and more — guide each rewrite pass toward natural-sounding prose.

Detector-in-Loop

On higher tiers, an ML detection model evaluates each rewrite during the loop. Detectors are an internal compass; we surface the resulting score so you can trust the output.

Your Data, Your Control

Every request carries a retention posture. Default is no retention beyond job lifetime and no upstream training. Opt in to allow_training for a discount, or strict_zdr for zero-data-retention paths.

Three steps to humanized prose

Submit your draft. We rewrite it. You receive prose that reads as human-written.

1

Submit your text

Paste a draft directly, upload a document, or call the REST API. Anything from a paragraph to a full article.

2

Rewrite under detector guidance

NaturalOutput rewrites your text across multiple passes. On higher tiers, a detector runs in the loop and steers each pass toward more natural prose.

3

Get humanized output

Receive the rewritten text plus a document-level score so you can see how the rewrite shifted the stylometric signal.
