Strip the AI packaging. Keep the meaning.

patina is a deterministic, pattern-based humanizer for Korean, English, Chinese, and Japanese. It finds AI-sounding phrasing and rewrites it without changing the claim, numbers, polarity, or causation.

It is not a black-box paraphraser, authorship detector, or detector-bypass tool. patina is built for allowed AI-assisted drafting where the author wants cleaner voice, an audit trail, and meaning-preservation checks.

Demo

--preview is the main sample: patina snapshots a live URL or local .html, rewrites only the prose blocks, and renders the result back onto the page. The floating bar switches between Rewritten / Original / Both / Diff, jumps between every changed block, and shows the deterministic score before → after.

patina --preview --lang en page.html         # a local .html file
patina --preview https://example.com/post     # or a live URL

The sample keeps the page structure, headings, CTA, and concrete facts (30 templates, planning docs, handoffs). It removes inflated phrasing like “innovative solution,” “transform productivity,” and “new paradigm” with an inline audit trail instead of a black-box paraphrase.

Quick Start

Browser audit

Open patina.vibetip.help to score KO / EN / ZH / JA text in your browser. The playground is audit-only: it does not rewrite text, call external LLMs, or send API keys to a server. For Korean, the browser and CLI may surface translationese / koPostEditese.v1 metadata as editing hints; this metadata is advisory only, is not calibrated score input, and must not drive hot paragraphs, gates, severity, baselines, percentiles, benchmark claims, prompt/rewrite gates, or authorship verdicts.

Agent skill

Claude Code — plugin marketplace (no clone, recommended):

/plugin marketplace add devswha/patina
/plugin install patina@patina

Claude Code · Codex CLI · Cursor · OpenCode — install script:

curl -fsSL https://raw.githubusercontent.com/devswha/patina/main/install.sh | bash

Then run the skill from Claude Code, Codex CLI, Cursor, or OpenCode:

/patina --lang en

[paste your text here]

Useful skill calls:

/patina --tone narrative
/patina --tone auto --lang en

Standalone CLI

Requires Node.js >= 18.

npx patina-cli doctor
npx patina-cli --lang en input.txt

Use a logged-in local model CLI without an API key:

printf '%s\n' 'Coffee has emerged as a pivotal cultural phenomenon.' \
  | npx patina-cli --lang en --backend codex-cli

Supported local backends: codex-cli, claude-cli, gemini-cli, kimi-cli. Without --model, patina passes the strongest documented default per backend: gpt-5.5 for OpenAI/Codex, claude-sonnet-4-6 for Claude, gemini-2.5-pro for Gemini, and kimi-code/kimi-for-coding for Kimi Code.
