I Built an AI SEO Content Generator — Generate 2000-Word Articles in 60 Seconds

Content marketers and bloggers spend hours writing SEO-optimized articles. I built WriteKit to cut that down to 60 seconds.

What WriteKit Does

You enter a keyword and select your preferences:

  • Article type: Blog post, product review, how-to guide, or listicle
  • Language: English, Chinese, Japanese, or Korean
  • Word count: 1,500 to 3,000 words
  • Tone: Professional, casual, academic, or friendly

Hit "Generate" and get a complete, SEO-optimized article with:

  • SEO title with your target keyword
  • Meta description (150-160 characters)
  • Structured H2/H3 headings
  • Natural keyword density (3-5 mentions)
  • Internal linking suggestions

The Tech Stack

Layer Technology
Framework Next.js 14 (App Router)
AI Engine OpenAI GPT-4o-mini
Auth NextAuth.js (GitHub + Google)
Database Supabase (Postgres)
Payments LemonSqueezy
Deployment Vercel

How the AI Generation Works

The core is a carefully crafted prompt that instructs GPT-4o-mini to:

  1. Research the topic thoroughly
  2. Structure the content with proper heading hierarchy
  3. Include the target keyword naturally
  4. Write in an engaging, human-like tone
  5. Add internal linking anchor text suggestions

The response streams in real-time using ReadableStream, so you see the article being written character by character — like watching a fast typist.

Pricing

  • Free: 1 article/day, 1,500 words max, English only
  • Pro: $19/month — Unlimited articles, 3,000 words, all languages
  • Business: $49/month — Everything + API access + bulk generation
