How do I make AI writing not sound like AI?

Run your draft through the Humanizer skill. It's built to strip the predictable patterns that give AI away: overhyped phrases, fake-depth words like "highlighting" and "showcasing," template drama ("It's not X, it's Y"), and polite chatbot fluff. It keeps your core meaning but cuts the corporate perfume. Write fast with AI, then do a humanizing pass so it sounds like you.

What are the telltale signs of AI-generated writing?

A few give it away every time: overhyped phrases ("game-changing," "evolving landscape"), fake depth ("highlighting," "underscoring"), the "It's not X, it's Y" template, and chatbot fluff like "Great question!" If you spot those in your own drafts, that's the signal to run a humanizing pass. You don't have to ban them forever, just stop letting them run your whole voice.

How do I install the Humanizer skill?

Download the SKILL.md from its GitHub repo, place it in your local skills folder, and reload your skills list. Or, if you'd rather skip the file handling, paste the SKILL.md contents into Claude and ask it to create the skill for you. Then use it with "Use /humanizer on this draft: [paste draft]." It works in whichever way is easiest for your setup.

Most AI content is easy to spot.

You can still write fast with AI without sounding like AI.

This guide shows how to use the Humanizer skill to clean your drafts so they sound natural, direct, and actually like you.

Why this works

Most AI-generated writing has predictable patterns:

overhyped phrases ("game-changing," "pivotal moment," "evolving landscape")
fake depth ("highlighting," "underscoring," "showcasing")
template drama ("It's not X. It's Y.")
polite chatbot fluff ("Great question!", "Hope this helps!")

The Humanizer skill is built specifically to strip those patterns out and keep the core meaning intact.

If your content keeps sounding "technically correct but soulless," this is exactly the fix.

How to install the Humanizer skill

You can download the file directly from GitHub:

Humanizer SKILL.md

Then install it in whichever way is easiest:

Open the SKILL.md file in GitHub.
Copy the file contents (or download the file).
Place it in your local skills folder.
Reload Claude or refresh your skills list.

If you'd rather not do the file handling, paste the SKILL.md content into Claude and ask it to create the skill for you.

A quick before and after

Before (AI voice):

Great question! You're absolutely right. In today's evolving landscape, it's not just about creating content, it's about crafting a promise that resonates with your audience while showcasing your unique value.

After (human voice):

Most AI content sounds the same. Write your draft fast, then run a humanizing pass so it sounds like you, not a motivational toaster.

Same idea. Less corporate perfume.

Prompt to use

Use /humanizer on this draft: [paste draft]

What to watch for in your own writing

If you spot these, hit it with /humanizer:

"Let's delve into..."
"It's not X. It's Y."
"In today's fast-paced world..."
"This highlights the importance of..."
"Great question! You're absolutely right."

You don't need to ban these forever. Just stop letting them run your whole voice.
