Humanize (AI-Tell Remover)

Rewrites AI-sounding text into human-reading prose using countable gates for em dashes, banned words, and sentence-length spread.

Content & WritingIntermediate★ 370⑂ 40AI score 10/10Last updated: Jul 10, 2026

What it does

Rewrites flat or AI-generated text so it matches the statistical and stylistic fingerprint of human writing. Instead of vague "make it warmer" advice, it works from the nine signals detectors actually measure: perplexity, burstiness, hedge density, lexical repetition, structural markers, specificity, POS density, punctuation fingerprint, and RLHF assistant voice.

  • Seven hard rules: at most one em dash per 300 words (zero under 300), no semicolons, straight quotes only, a banned-vocabulary list (delve, leverage, robust, comprehensive...), no "not just X, it's Y" negation pivots, no preamble or changelog, and enforced sentence-length spread.
  • Nine levers: context-specific word choice, burstiness, hedge surgery, structural flattening, specificity anchors, voice and register, non-AI transitions, punctuation normalization, and stripping the helpful-assistant register.
  • Pre-output gate: re-read the draft and write literal counts plus quoted hits, then list every sentence's word count to prove the rhythm conditions pass.
  • Signal I audit: a per-paragraph checklist for patterns that feel like good writing but read as AI, such as mini-aphorism closers, tricolons, chiasmus, anaphora, and "turns out" pivots.

Who it's for

  • Content writers, newsletter authors, and LinkedIn posters who draft with AI and need a human voice
  • Professionals cleaning robotic tone out of reports, memos, and proposals
  • Writers who want their own voice preserved by supplying samples (protocol step 0 distills style hypotheses)
  • Editors auditing drafts for machine-writing habits

Examples

  1. Polish a draft: "humanize this newsletter section" and get back only the rewrite, with em dashes cut, hedges deleted, and a mix of 5-word fragments and 25-plus-word sentences.
  2. Match your voice: paste three past posts and ask for a rewrite in that register; the skill extracts 5-10 style hypotheses about sentence variance, openers, and verbal tics first.
  3. Diagnose: "why does this read as AI?" returns an inventory of hedge count, bullet overuse, sentence uniformity, and RLHF voice markers.
  4. Specificity warning: if the input has zero numbers, names, or dates, it still rewrites and then appends a note that real specifics are needed to pass the specificity signal.

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the humanize folder from the GitHub repo harshaneel/humanize into my ~/.claude/skills/humanize/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/harshaneel/humanize.git /tmp/humanize && mkdir -p ~/.claude/skills && cp -r /tmp/humanize/humanize ~/.claude/skills/humanize

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal (Terminal on macOS, WSL or Git Bash on Windows).
  2. Make sure the skills directory exists: mkdir -p ~/.claude/skills
  3. Clone the repo to a temp folder: git clone https://github.com/harshaneel/humanize.git /tmp/humanize
  4. Copy the skill folder into place: cp -r /tmp/humanize/humanize ~/.claude/skills/humanize
  5. Verify the files: ls ~/.claude/skills/humanize should show SKILL.md and a references folder.
  6. Restart Claude Code, then trigger it with a request like "humanize this paragraph" or "make this sound less AI".
  7. If the repo ships a companion skill such as ai-check, copy it the same way to get the grading pass too.
