WriteHuman alternative that shows its working
Teams comparing WriteHuman alternatives often like the straightforward humanizing experience but want to see what the rewrite changed and be confident the output still reads naturally. The question is whether one rewrite really rebuilds the prose or just reshuffles it.
WriteHuman is a clean, well-regarded humanizer in this space. Undetected.ai aims at the same outcome and leans into the wedge: one rewrite of the properties every detector measures, our own AI-pattern gauge with the reasons behind its number, and meaning-preserving prose so the humanized text is ready to use.

This is our own AI-pattern score, measured here on sentence rhythm, template phrases, vocabulary variety and passive voice. It is not a GPTZero, Turnitin, Originality.ai, Copyleaks or ZeroGPT result, and it does not predict one. Worth knowing: we also ask the rewrite to vary sentence length, drop template phrases and prefer the active voice, so some of the drop is built in. Read the two panels below, not just the number.

The short answer
Undetected.ai works well as a WriteHuman alternative if you want to read what the rewrite changed. Both humanize AI text; Undetected.ai shows our own AI-pattern score before and after with the reasons behind it, priced flat at $9, $19 and $39 a month billed yearly. WriteHuman meters by request rather than by word, which is cheaper if you humanize a few long documents instead of a steady stream.
