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

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

The Tech Stack
| Layer | Technology |
|---|---|
| Framework | Next.js 14 (App Router) |
| AI Engine | OpenAI GPT-4o-mini |
| Auth | NextAuth.js (GitHub + Google) |

How the AI Generation Works
The core is a carefully crafted prompt that instructs GPT-4o-mini to:
- Research the topic thoroughly
- Structure the content with proper heading hierarchy
- Include the target keyword naturally
- Write in an engaging, human-like tone
- 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.
