What It Is

AI-powered content rewriting library for OpenAI (gpt-4.1) with format auto-detection and configurable prompts.

Features

Format Auto-Detection

Automatically detects content format:

• HTML — preserves tags and structure
• Markdown — maintains formatting
• Plain text — simple rewriting

Prompt Templates

Available templates:

• Default — universal rewrite preserving language
• Custom — your own instructions

Anti-AI Detection

Automatically masks common AI patterns:

• Em-dashes → regular dashes
• Formal phrases → casual alternatives
• Typical AI phrases → natural variations
• Overly structured patterns → more natural flow

Large Content Handling

Content over 12,000 characters automatically split into chunks and processed in parallel.

Cost Tracking

const result = await rewriter.rewrite(content);
console.log(`Cost: $${result.cost.toFixed(4)}`);

NPM Package

npm install @affiliate.fm/ai-content-rewriter

import { ContentRewriter } from "@affiliate.fm/ai-content-rewriter";

const rewriter = new ContentRewriter({
  provider: "openai",
  apiKey: process.env.OPENAI_API_KEY,
});

// Single variant
const [result] = await rewriter.rewrite("<h1>Title</h1><p>Content...</p>");

// Multiple variants
const results = await rewriter.rewrite(content, { variants: 5 });
