I got Claude to write like a human. The setup takes 2 minutes.

I use Claude every single day. Uncle Claude handles the boring parts of my work, and I tell my mentees to let him do the same for their job search. But raw AI output has a fingerprint, and people who read a lot of it learn to spot that fingerprint fast.

Recruiters read hundreds of applications a month. After enough of them, AI-polished writing starts to glow in the dark. The same warm openers keep appearing, and every sentence sits at that comfortable medium length. At some point you stop reading words and start seeing the template.

There's research behind that instinct too. Wikipedia's guide to AI writing cites research where heavy AI users correctly picked out AI-generated text about 90% of the time. Recruiters read AI text all day long. You can guess which group they fall into.

Look, if you're using AI for your applications, your LinkedIn posts, your work emails: no judgment. Research from the hiring platform Greenhouse found about 3 in 4 US job seekers now use AI somewhere in their search. At this point you'd almost be strange not to.

The trouble starts when the writing sounds like it.

The 20-second read

A TopResume survey of 600 US hiring managers found roughly 1 in 5 would reject a candidate whose resume or cover letter reads as AI-generated. Over a third said they can spot an AI-written resume in under 20 seconds.

Twenty seconds. That's the entire read your application gets before an opinion forms.

A field experiment published through the National Bureau of Economic Research followed 480,948 job seekers and found that people who got algorithmic help with their writing were 8% more likely to get hired. So the tool works. The candidates it hurt were the ones who let it speak in its own voice instead of theirs.

Hold both of those numbers at once and the real rule appears: AI can carry the typing, as long as the finished text sounds like you.

This goes way past job applications

Think about how your manager actually experiences your work. Emails. Project updates. The summary you send after a client call. How much tweaking are you actually doing to make things sound more like you?

Writing is how your thinking shows up when you're not in the room. It's the thing that gets forwarded upward when promotion conversations happen. And when every update you send carries the same chatbot gloss as everyone else's, you become genuinely hard to remember.

Same story on LinkedIn. The feed is packed with posts that all sound like the same ghostwriter. A post that reads like an actual person now stands out on contrast alone, and if personal branding is the new CV (I've built my whole thing on that), then your voice is the brand. Let Uncle Claude do the typing but remember the voice has to stay yours.

A reference doc written by people who read AI slop all day

Wikipedia's editors got flooded with AI-written submissions. The cleanup crew that reviews them kept a running list of every pattern that kept turning up: the em dashes, the word "delve," the "it's not just X, it's Y" construction, and the endings that restate everything you just read.

That list became a page called Signs of AI writing.

It runs about 15,000 words, with real examples for every tell. It's a reference document, plain and simple, and it's free. Nobody's memorizing 15,000 words though. You're going to hand it to Claude. 🧠

The 2-minute setup ✍️

Here's what works:

1️⃣ Go to Google and type "signs of AI writing." Open the Wikipedia page (it's titled "Wikipedia:Signs of AI writing").

2️⃣ Print the page and save it as a PDF. Hit Ctrl+P (Cmd+P on Mac) and set the destination to "Save as PDF."

3️⃣ Open Claude, upload that PDF, and send this exact prompt:

"Create a skill that will help me humanize all writing and output that I create moving forward. I want you to avoid using all the Signs of AI writing when using this skill"

4️⃣ Claude reads the document and builds the skill. Once the skill has been created, save it.

5️⃣ From now on, when you open a new chat for anything, type /humanize and the skill runs on whatever you're working on.

That's the whole setup. Cover letters, LinkedIn posts, follow-up emails after interviews, and that message to your manager about the raise conversation. One command and the robot voice comes off.

What actually changes

Here's a line the old way:

"I am excited to leverage my extensive experience to drive impactful results in a dynamic, fast-paced environment."

That sentence could belong to anyone, applying anywhere. Run the same idea through the skill, push for your real details, and you land somewhere like:

"I spent three years running weekend operations for a warehouse that shipped 4,000 orders a day. I want to bring that to your team."

A recruiter reading 200 applications a week remembers exactly one of those.

One warning before you run off

The skill fixes how the writing sounds. The substance still has to be yours: real numbers from your work, and stories you can back up when the interviewer asks a follow-up question. Recruiters forgive clumsy-but-true a lot quicker than smooth-but-empty.

And if you're upskilling right now, put this near the top of the list. Every job description asks for AI skills, and pasting a prompt into a chatbot doesn't cover it. Using the tool without sounding like the tool is the actual skill, and the person who drafts a project update with AI in half the time while still sounding like themselves is the person who gets handed bigger things.

Try this with the next thing you write. Read it out loud before you send it. If it sounds like you explaining your work to a friend, hit send. A press release about a stranger gets one command first: /humanize. ⚡

Your career runs on your words more than you think. Interviews and coffee chats end, and what stays behind in inboxes and feeds is your writing. It speaks for you at 2am in time zones you've never visited. Make sure it sounds like someone worth meeting.

If this helped, share it with one friend who's deep in the job hunt right now, and follow along. I write these every week to make the job search feel less like a black box.

Peace. ✌️
