human-voice

Make AI-drafted docs read like a person wrote them, without changing a single fact.

human-voice is a Claude Code skill that rewrites or generates prose so it doesn't read as AI-written. Most "humanizer" tools swap a few words and call it done. The text still reads like a machine, because the giveaways aren't mostly lexical. They're structural (em-dash overuse, relentless rule-of-three, bold-bullet listicles, sentences that are all the same length) and substantive (paragraphs that say nothing, a survey where a verdict belongs, invented specifics). This skill fixes those first and treats word choice as the last and shallowest pass.

Your team keeps its notes in six different tools. By Friday nobody
remembers which thread held the real decision. Put the chat right
next to the files, in one place, so "wait, where did we land on this?"
stops being a question anyone has to ask.

The "before" isn't a vocabulary problem. It's the whole machine signature at once: filler (leverage, delve, seamless), business jargon (move the needle, actionable), a reflexive rule-of-three, the it's not X, it's Y reflex, puffery (stands as a testament). Swap the synonyms and all of that still stands. The skill strips it out and commits to one concrete claim.

Why use it

• It fixes the tells that actually give AI away. The signature is structural and substantive, not just word choice. human-voice cuts vacuity, breaks uniform sentence rhythm (what detectors call burstiness), dismantles the rule-of-three and bold-bullet templates, and makes the text take a position. Diction comes last.
• Nothing gets fabricated to sound human. Numbers, quotes, citations, defined terms, code: all invariant. When a draft needs a fact it doesn't have, the skill writes [SOURCE NEEDED] instead of inventing one. The anti-hallucination protocol is built in.
• The genre comes first, never one default voice. A technical report stays professional. Marketing copy addresses "you". A blog post gets a personality. Ten register profiles share one universal core of tells fixed everywhere.
• A bundled linter gates your CI. The dependency-free Python script scores the regex-able tells and prints a verdict; past a threshold you set with --fail-over, it exits non-zero. It says plainly what it can't see.
• No detector games. No homoglyph or zero-width tricks, no deliberate typos. The goal is writing a skeptical human reads as human, not a passing score. AI detectors also misclassify non-native-English writing as machine-made (Liang et al. 2023), so no detector is ground truth anyway.

Use

/human-voice <file-path | pasted-text> [fix|generate] [register: technical|business|marketing|academic|casual|creative]

• fix (default) rewrites an AI-sounding draft.
• generate drafts new copy that reads human from the start.
• register matches the genre's conventions; it's inferred if you omit it.
