Human Writer

Edit text so it reads like a person wrote it, not a language model.

Adapted from the Humanizer skill (based on Wikipedia's Signs of AI writing), with additions from Andi Search's AI-slop classification system, Orwell's "Politics and the English Language" (1946), and Paul Graham's writing advice.

Why This Matters

AI search tools (ChatGPT, Perplexity, etc.) cite few sources per response. Graphite (2025) found 82% of those citations are human-written. Content that reads as AI-generated gets filtered or deprioritized. If you want AI systems to surface your writing, it has to pass as human.

Andi Search filters 40-50 million pages of AI slop per day from their index. The patterns below are the same ones classifiers use to bin content.

If you are a non-native English speaker, pay extra attention. You are less likely to notice AI tells in your own output because the phrasing may sound fine to you even when it screams "machine-generated" to native readers.

The One Rule

Let AI help with drafts and structure. Keep the thinking yours.

Original ideas and genuine expertise still beat any style fix. If the thinking is generic, no amount of polish will help.

Hemingway called this the iceberg theory: "The dignity of movement of an iceberg is due to only one-eighth of it being above water." His point: you have to know more than you write in order to write well.

Two corollaries:

Be specific. "$15K MRR, growing 50% month over month" beats "experiencing significant growth." Numbers, names, and concrete details are persuasive because readers can verify them. "Commitment to excellence" says nothing.

Use short words. That is how people actually talk. "We built this" instead of "this was constructed by our team." If you would not say "utilize" out loud, write "use."

---

Voice and Personality

Avoiding AI patterns is half the job. Sterile, voiceless writing is just as obvious as slop.

Signs of soulless writing (even when "clean")

• Every sentence is the same length and structure
• No opinions, just neutral reporting
• No first-person perspective when it would be natural
• No humor, no edge, no personality
• Reads like a Wikipedia article or press release

How to add voice

Have opinions. "I genuinely don't know how to feel about this" is more human than neutrally listing pros and cons.

Vary rhythm. Short punchy sentences. Then longer ones that take their time. Mix it up.

Acknowledge complexity. Real humans have mixed feelings. "This is impressive but also kind of unsettling" beats "This is impressive."

Use "I" when it fits. First person is not unprofessional. "I keep coming back to..." or "Here's what gets me..." signals a real person thinking.

Let some mess in. Perfect structure feels algorithmic. Tangents, asides, and half-formed thoughts are human. Text that perfectly follows every writing rule is itself a tell. One reader correctly identified an AI-written post because "there's no sentence or paragraph that doesn't follow some clear/concise chain of thought." Humans write messily.

Be specific about feelings. Not "this is concerning" but "there's something unsettling about agents churning away at 3am while nobody's watching."

Be inconsistent on purpose. AI is unnervingly consistent about small style choices — punctuation always inside quotes, or always outside. Parallel structure in every list. Humans are naturally inconsistent about these things. If you notice robotic consistency in punctuation, capitalization, or list structure, break the pattern.

Audit Priority

Newer models have largely fixed the obvious vocabulary tells ("delve", "in the realm of"). They have gotten worse at structural patterns: contrastive negation, pseudo-profound flourishes, elegant variation, and rule-of-three. Prioritize those during review. The vocabulary list still matters because models regress unpredictably and because older drafts may use older models.

---

Patterns to Fix

1. AI Vocabulary

Delete on sight:

delve, crucial, pivotal, vibrant, vital, foster, showcase, underscore, landscape (abstract), tapestry (abstract), testament, intricate, interplay, garner, enhance, boasts, groundbreaking (figurative), renowned, nestled, Additionally

Delete these phrases:

"in the realm of", "excited to announce", "let's dive in", "plays a key role", "commitment to excellence", "it's important to note", "in conclusion"

Replace:

AI version	Write instead
serves as	is
stands as	is
utilize	use
facilitate	help
leverage	use
in order to	to
due to the fact that	because
at this point in time	now
has the ability to	can

2. Significance and Legacy Inflation

AI puffs up importance by claiming everything "marks a pivotal moment" or "underscores the significance of broader trends."

Before:

The Statistical Institute of Catalonia was officially established in 1989, marking a pivotal moment in the evolution of regional statistics in Spain.

After:

The Statistical Institute of Catalonia was established in 1989 to collect and publish regional statistics independently from Spain's national statistics office.

Words to watch: stands/serves as, is a testament/reminder, vital/significant/ crucial/pivotal role, underscores/highlights importance, reflects broader, symbolizing ongoing/enduring, setting the stage for, represents a shift, evolving landscape, indelible mark, deeply rooted. See also pattern 15 for the rhetorical variant in editorial and tech writing.

3. Promotional Language

AI struggles to keep a neutral tone. Everything becomes a tourist brochure.

Before:

Nestled within the breathtaking region of Gonder, Alamata stands as a vibrant town with a rich cultural heritage and stunning natural beauty.

After:

Alamata is a town in the Gonder region of Ethiopia, known for its weekly market and 18th-century church.

Words to watch: boasts, vibrant, rich (figurative), profound, enhancing, showcasing, exemplifies, commitment to, natural beauty, nestled, in the heart of, groundbreaking, renowned, breathtaking, must-visit, stunning.

4. Superficial -ing Padding

AI tacks present-participle phrases onto sentences to simulate depth.

Before:

The temple's colors resonate with the region's beauty, symbolizing local bluebonnets and the Gulf coast, reflecting the community's deep connection to the land.

After:

The temple uses blue, green, and gold. The architect said these reference local bluebonnets and the Gulf coast.

Watch for: highlighting, underscoring, emphasizing, ensuring, reflecting, symbolizing, contributing to, cultivating, fostering, encompassing, showcasing.

5. Vague Attributions

AI attributes opinions to unnamed authorities instead of citing sources.

Before:

Experts believe it plays a crucial role in the regional ecosystem.

After:

The river supports several endemic fish species, according to a 2019 survey by the Chinese Academy of Sciences.

Name sources. "Graphite found" beats "studies show." Numbers and named customers work because readers can verify them.

6. Copula Avoidance

AI substitutes elaborate constructions for "is" and "are."

Before:

Gallery 825 serves as LAAA's exhibition space. The gallery features four spaces and boasts over 3,000 square feet.

After:

Gallery 825 is LAAA's exhibition space. The gallery has four rooms totaling 3,000 square feet.

Replace: serves as, stands as, marks, represents, functions as, boasts, features, offers -> is, are, has.

7. Rule of Three

AI forces ideas into groups of three to appear comprehensive.

Before:

The event features keynote sessions, panel discussions, and networking opportunities. Attendees can expect innovation, inspiration, and industry insights.

After:

The event includes talks and panels. There's also time for informal networking between sessions.

Vary list lengths. Three is not always wrong, but always three is a tell.

8. Negative Parallelisms and Contrastive Negation

"Not only X but Y" and "It's not just X, it's Y" are AI favorites. So is reframing a straightforward point as a "real question" to sound deeper.

Before:

It's not just about the beat; it's part of the aggression and atmosphere. It's not merely a song, it's a statement. The real question isn't whether we should adopt AI, it's whether we can afford not to.

After:

The heavy beat adds to the aggressive tone. We plan to adopt AI tools next quarter.

Use these constructions only when making genuine distinctions, not to sound deep.

9. Elegant Variation (Synonym Cycling)

AI has repetition-penalty code that forces synonym substitution. Just repeat the word.

Before:

The protagonist faces challenges. The main character must overcome obstacles. The central figure eventually triumphs. The hero returns home.

After:

The protagonist faces many challenges but eventually triumphs and returns home.

10. False Ranges

AI uses "from X to Y" where X and Y are not on a meaningful scale.

Before:

Our journey has taken us from the singularity of the Big Bang to the grand cosmic web, from the birth of stars to the enigmatic dance of dark matter.

After:

The book covers the Big Bang, star formation, and current theories about dark matter.

11. Em Dash Overuse

AI uses em dashes more than humans, mimicking punchy sales writing. Use commas and periods instead.

Before:

The term is primarily promoted by Dutch institutions — not by the people themselves. You don't say "Netherlands, Europe" — yet this continues — even in official documents.

After:

The term is primarily promoted by Dutch institutions, not by the people themselves.

12. Inline-Header Lists and Boldface

AI outputs lists with bolded headers + colons. Rewrite as prose or simple lists.

Before:

• User Experience: The UX has been significantly improved.
• Performance: Performance has been enhanced through optimized algorithms.
• Security: Security has been strengthened with end-to-end encryption.

After:

The update improves the interface, speeds up load times through optimized algorithms, and adds end-to-end encryption.

Also: avoid emojis in headings or bullet points, and prefer sentence case over Title Case in headings.

Bulleted checklists themselves are becoming an AI tell. When possible, rewrite bullet lists as prose or at least vary their structure. A wall of tidy bullets reads like AI copy-editing even if the words are fine.

13. Filler, Hedging, and Generic Conclusions

Filler to cut:

• "In order to achieve this goal" -> "To achieve this"
• "It is important to note that the data shows" -> "The data shows"
• "The system has the ability to process" -> "The system can process"

Hedging to fix:

Before: "It could potentially possibly be argued that the policy might have some effect." After: "The policy may affect outcomes."

Generic conclusions to kill:

Before: "The future looks bright. Exciting times lie ahead as we continue this journey toward excellence." After: "The company plans to open two more locations next year."

14. Communication Artifacts

Delete chatbot artifacts that got pasted into content:

• "Great question!", "I hope this helps!", "Let me know if you'd like..."
• "Certainly!", "Of course!", "You're absolutely right!"
• "As of my last training update..."
• "While specific details are limited based on available information..."

15. Pseudo-Profound Flourishes

AI loves grand framing that says nothing. State what something does. Skip the grandiose.

Delete:

"This changes everything." "The implications are staggering." "We're witnessing the emergence of..." "This is just the beginning." "The future of X is Y."

16. Dying Metaphors

Orwell (1946): never use a metaphor you are used to seeing in print. Worn-out metaphors have lost their power to evoke images.

Avoid: "toe the line", "Achilles' heel", "level playing field", "play into the hands of", "hotbed", "at the end of the day."

Use simple verbs (break, stop, mend, kill) instead of phrases built around prove, serve, form, play, render.

17. Staccato and Monotone Rhythm

Avoid 4+ short declarative sentences in a row. Connect ideas with "because", "so", "which means" instead of listing isolated statements.

Before:

The experiment produced interesting results. The agents generated 3 million lines of code. Some developers were impressed. Others were skeptical. The implications remain unclear.

After (informal editorial register; adjust voice to fit your context):

I genuinely don't know how to feel about this one. 3 million lines of code, generated while the humans presumably slept. Half the dev community is losing their minds, half are explaining why it doesn't count.

18. Extrapolation to Universal Principles

AI generalizes a specific observation into a sweeping universal claim.

Before:

Once you experience fast deploys, slow CI feels completely unacceptable. After switching to TypeScript, going back to plain JavaScript feels wrong.

After:

Fast deploys cut our release cycle from two weeks to a day. We switched to TypeScript because it caught three bugs in the first week.

Just state what you did and what happened. Skip the "once you X, you can never go back" framing.

Quick Reference: Orwell's Rules (1946)

1. Never use a metaphor you are used to seeing in print.
2. Never use a long word where a short one will do.
3. If you can cut a word, cut it.
4. Never use passive where you can use active.
5. Never use jargon if you can think of an everyday equivalent.
6. Break any of these rules sooner than say anything barbarous.

If you wouldn't say it that way to a friend, rewrite it. (Paul Graham)

Process

Work in two passes. A single pass rarely catches everything because models actively resist style corrections — they will ignore explicit instructions about voice and structure even when those instructions are right there in the prompt. This is why the second pass matters.

Pass 1: Draft with awareness

1. Start from the writer's own ideas, thinking, and specific details. Inject research and source material. The quality of input determines the quality of output — a vague prompt produces generic slop regardless of style rules.
2. Draft with the patterns above in mind.
3. Preserve meaning and match the intended tone (formal, casual, technical).

Pass 2: Audit against the checklist

4. Scan the draft for every pattern above. Fix each one.
5. Revise for voice. Ask: "What makes this so obviously AI-generated?" Fix remaining tells.
6. Read aloud. Does it sound like a person or a press release?

Em dashes and elegant variation are the hardest patterns to suppress. If the text still has them after revision, run a targeted third pass for just those. Em dashes in particular are "baked in pretty hard" to current models.

Output Format

Provide:

1. Revised text
2. Brief list of remaining AI tells (if any) and how you fixed them
3. Summary of changes (optional, if helpful to the user)
