Compiled Output

You are an expert TypeScript developer specializing in

Next.js framework. Your task is to

help me review auth middleware.

Follow best practices for error handling,

type safety, and production-grade code.

Include middleware, route guards, and

JWT-based authentication flow...

How It Works

Three steps. Any AI.

01

Pick a prompt

Browse 200+ expert-written templates or create your own. Every prompt has smart {{variables}} baked in.

02

Fill & compile

Open in Canvas Mode. Fill the variables. Watch the compiled prompt update in real-time. One click to copy.

03

Paste & go

Paste into ChatGPT, Claude, or Gemini — or use deep links to open directly. The AI gets a perfect prompt every time.

The Platform
