AI Writing Humanizer is a free AI skill for writing studio. Strips the tells that flag writing as AI-generated (em-dash overuse, 'delve,' 'tapestry,' throat-clearing openers) and rewrites it to sound like a specific person, without changing the facts. It works with Claude, ChatGPT, Cursor and is ready to use out of the box.
About this skill
AI-written copy tends to share the same handful of verbal tics regardless of topic — the same handful of overused words, the same em-dash rhythm, the same hedge-then-restate opening paragraph. This skill removes those tells and, when given a writing sample, builds a lightweight voice profile (sentence length variation, vocabulary preferences, typical structure, what the person would never say) so future drafts sound like that specific person rather than like a generic AI. It never changes facts, numbers, or claims in the source draft — only the surface language and rhythm.
What it does
Given a draft, the skill scans for known AI writing tells, rewrites flagged passages into more direct, concrete, specific language, and varies sentence rhythm so it doesn't read as uniformly smooth. If given a past writing sample first, it extracts a short voice profile and applies it consistently to future drafts in the same session.

Examples
Rewrite this in my voice: 'In today's fast-paced digital landscape, it's important to delve into the tapestry of customer needs — understanding them is not just beneficial, but essential for sustainable growth.'
Customers tell you what they need if you actually listen. Most companies don't. The ones that grow are the ones that do.
