Original: I Built an AI-Powered 'Sarcastic Code Reviewer' (And how you can too!)

Short summary

A hands-on tutorial for building a sarcastic AI code reviewer using HTML, CSS, JavaScript, and Hugging Face's free Qwen2.5-Coder-7B-Instruct model. The app roasts bad HTML markup and praises semantic HTML with dry sarcasm. Includes full frontend code, a system prompt defining the AI personality, and a live CodePen demo.

  • Uses Hugging Face Inference API with Qwen2.5-Coder-7B-Instruct — no backend or paid API keys needed
  • System prompt defines a sassy senior frontend developer persona for code review
  • Full client-side implementation with HTML, CSS, and JavaScript in under 10 minutes

Generated with AI, which can make mistakes.
