Build an AI copy humanizer skill with a feedback loop

Create a reusable Claude Code and Antigravity skill that scores AI-written copy, diagnoses what feels synthetic, rewrites it in a real voice, and improves after each run.

What you will have

A review-and-rewrite skill that catches AI-sounding copy, applies a scoring rubric, rewrites drafts in a chosen voice, and updates itself from feedback.

Setup time
3-5 hours for first usable skill
Time saved
2-4 hours per batch of copy reviews
Estimated cost
$20 to $200 per month

Why this works

Prompting AI to sound human often fails because the instruction is too vague. A humanizer skill works better when it scores the draft first, names the patterns that feel artificial, and then rewrites against a specific voice baseline. The feedback loop matters because every awkward draft teaches the skill a new anti-pattern to catch next time.

1

Collect voice samples and anti-examples

45-60 min

Create a Google Docs folder with 5-10 writing samples that actually sound like the person or brand you want to emulate. Include LinkedIn posts, emails, landing page sections, internal notes, or transcripts if they capture natural phrasing. Add 5 examples of AI-written copy that feels wrong and annotate why: too polished, too symmetrical, too generic, too many transitions, no domain specificity, or no real opinion. The skill needs both positive and negative examples to learn what to preserve and what to avoid.

Output

A voice source folder with real writing samples, weak AI examples, and annotation notes.

Google Docs
Pro tip

The best voice samples are often less polished than you expect. Clean corporate copy may be approved, but it rarely teaches rhythm, personality, or judgment.

2

Define the four-part scoring rubric

45 min

Create a scoring rubric with four 1-10 categories: AI likeness, authenticity, reader value, and domain credibility. For each category, define what scores 1, 5, and 10 look like, and include common failure patterns. Store the rubric in Google Docs and add a Google Sheets tracker with columns for draft type, score, diagnosis, rewrite decision, reviewer feedback, and rule added. QA check: a reviewer should be able to score the same draft within one point of the skill.

Output

A copy review rubric and score tracker that the skill can apply consistently.

Pro tip

Do not make the score only about sounding human. A casual but empty rewrite can score low on reader value or domain credibility even if it sounds less robotic.

Expected results

Review speed

2-4 hours saved per batch

The skill handles first-pass scoring, diagnosis, and rewrite suggestions so editors focus on judgment and final polish.

Copy quality

Scores plus diagnosis

The workflow explains why a draft feels artificial instead of only producing a different-sounding rewrite.

Voice consistency

Source-sample grounded rewrites

Real writing samples and anti-examples make the output more specific than generic tone instructions.

Skill improvement

Rule updates after real feedback

The skill compounds because repeated reviewer corrections become explicit instructions.
