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.
Stylometric signals, detector-in-loop verification, and a hardened security pipeline — engineered to produce prose that reads as human-written.
24 stylometric signals — sentence variability, vocabulary diversity, burstiness, and more — guide each rewrite pass toward natural-sounding prose.
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.
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.
Submit your draft. We rewrite it. You receive prose that reads as human-written.
Paste a draft directly, upload a document, or call the REST API. Anything from a paragraph to a full article.
NaturalOutput rewrites your text across multiple passes. On higher tiers, a detector runs in the loop and steers each pass toward more natural prose.
Receive the rewritten text plus a document-level score so you can see how the rewrite shifted the stylometric signal.
NaturalOutput adapts to the way you work — whether you're polishing an essay, managing a content team, or building integrations.
