Humanizer
AI-generated text has a recognizable accent. Readers in 2026 pattern-match it in seconds, and the moment they detect it, trust drops: the writing reads as low-effort, and the sender reads as someone who couldn't be bothered. This skill removes the accent. The goal is not to trick anyone; it is to make writing sound like the specific person who sent it, because generic voice fails at the one job writing has: being read.
Every rule below exists because the pattern it bans is statistically overrepresented in AI output. Individually each is harmless; a human might use any one of them. It's the density that gives it away. You are managing density.
The kill list: punctuation and structure
Em dashes (—). The single loudest tell. Do not use them, even correctly. Restructure instead:
- Two sentences: "The launch failed. Nobody had tested payments."
- A comma: "It works, mostly."
- Parentheses for true asides: "The budget (all $40 of it) ran out."
- A colon when introducing: "One thing mattered: speed." Do not replace em dashes with spaced hyphens ( - ) as a mechanical swap; if the sentence needed a dash, it usually needed restructuring.
Formulaic rhythm. These constructions are fingerprints:
- The negation pivot: "It's not just X, it's Y." / "This isn't about X. It's about Y."
- The rule of three, everywhere: "faster, smarter, and more reliable." One triple per piece, maximum. Prefer pairs or single adjectives.
- Perfectly parallel sentences and paragraphs of identical length. Humans write lopsided. Vary hard: follow a 30-word sentence with a 4-word one.
- "Whether you're a beginner or a seasoned pro..."
- Ending every section with a tidy summary sentence.
Structural tells:
- Bullet points for content that should be prose. Bullets are for genuine lists, not for thinking.
- The bold-term-colon pattern repeated down a page. (Used sparingly in a reference doc, fine. As the skeleton of an essay, a tell.)
- Headers on a 400-word piece. Short writing doesn't need navigation.
- An intro that announces what the piece will say and a conclusion that repeats what it said. Cut both. Start inside the point; stop when done.
- Emoji as section decoration.
The kill list: words and phrases
Never use these. Each has a plain replacement or can simply be cut:
delve, tapestry, testament, landscape (metaphorical), realm, journey (metaphorical), embark, unlock, unleash, elevate, empower, supercharge, game-changer, seamless, robust, leverage (as a verb), utilize, navigate (metaphorical), dive into, deep dive, at the end of the day, in today's fast-paced world, in an era of, it's important to note, it's worth noting, notably, moreover, furthermore, additionally (sentence-initial), thus, hence, overall (sentence-initial), in conclusion, ultimately, boasts, vibrant, bustling, nestled, rich history, hidden gem, must-visit, comprehensive, crucial, pivotal, foster, harness, streamline, cutting-edge, state-of-the-art, best-in-class, look no further, rest assured, I hope this email finds you well, please don't hesitate, feel free to.
Replacements are boring on purpose: "use" not "utilize", "big" not "significant", "helps" not "empowers", "also" not "additionally". If a banned word carries real meaning in context (e.g., "robust" in a statistics paper), keep it; the ban targets decoration, not meaning.
What humans do instead
Specifics over abstractions. "Increased efficiency across multiple workflows" says nothing. "Cut invoice processing from two days to twenty minutes" says everything. When the source text is vague, ask the user for the concrete detail rather than inventing one.
Contractions. It's, don't, we're, can't. Their absence is stiffness. (Exception: keep the user's register; a formal legal letter stays formal.)
Claims with an owner. AI hedges into mush: "This could potentially be seen as somewhat problematic." A person writes: "I think this is a mistake." One hedge is honest; three is evasion.
Mild imperfection. Fragments are fine. Starting with And or But is fine. A slightly informal aside is fine. Do NOT fake typos or inject slang; overcorrection into forced casualness is its own tell, and worse than the original stiffness.
Write like you'd say it. The test for any sentence: would the user plausibly say this out loud to a colleague? "I wanted to reach out to touch base regarding..." fails. "Quick question about..." passes.
Workflow
- Establish voice. If rewriting the user's text, their existing word choices, formality level, and quirks are the target voice; preserve them. If drafting fresh, ask for or infer register (who's reading it, what's the relationship) before writing.
- Rewrite at sentence level, not word level. Swapping banned words for synonyms leaves the robotic skeleton intact. Restructure the sentence around its actual point.
- Preserve every fact. Humanizing must not change meaning, numbers, names, or commitments. If shortening loses a fact, keep the fact.
- Do a density pass. Reread the output hunting for: any em dash, any kill-list word, more than one triple, uniform paragraph lengths, a throat-clearing opener, a summarizing closer. Fix what you find before showing the user.
- Show, don't lecture. Return the rewritten text. Only explain the changes if asked, and never annotate the text with meta-commentary.
Example
Before (AI accent): "In today's fast-paced business landscape, effective communication is crucial. Our comprehensive platform doesn't just streamline workflows — it empowers teams to unlock their full potential. Whether you're a startup founder or a seasoned executive, our robust suite of tools will elevate your productivity journey."
After (human): "Most teams waste hours a week on status updates. Ours cuts that to one 15-minute sync. We built it for our own team first, and we still use it every day."
Note what changed: the abstraction became a number, the em dash became a period, the audience-pandering line disappeared, and the credibility now comes from a concrete detail instead of adjectives.
Register warning
Humanizing is not the same as casualizing. A condolence note, a board memo, and a group-chat message are all human, and none of them sound alike. Match the situation. The skill removes the AI accent from whatever register the writing needs, it does not drag everything toward breezy startup-speak.
