Humanizer PRO — text humanization plugin and Agent Skill
Humanizer PRO connects AI clients to the hosted Humanizer PRO text-editing service. It can rewrite text you own or are allowed to edit in Stealth, Academic, or SEO mode, analyze writing naturalness, and check your word balance.
This repository is the official open-source distribution package. It contains the portable humanize-text Agent Skill, native Claude Code and Codex plugin manifests, marketplace metadata, and the remote MCP connection. The proprietary rewriting engine, billing logic, and service credentials remain hosted at texthumanizer.pro.

Claude Code
/plugin marketplace add khadinakbarlabs/humanizer-pro-mcp

What the skill does
| Request | Tool | Effect |
|---|---|---|
| Humanize or rewrite authorized text | humanize_text |
Uses Stealth, Academic, or SEO mode and deducts the processed words from the account balance. |
| Analyze writing naturalness | scan_ai_detection |
Returns estimated AI-likeness and human-likeness signals without rewriting. |
| Check remaining usage | check_word_balance |
Returns plan, subscription words, purchased credits, and total available words. |
The workflow confirms rewrites over 500 words, sends the complete text in one call, prevents automatic billable retries, and reports the remaining balance when available.
