Role: you are an expert in content that works across platforms.

My idea: [your idea]
My niche: [niche]

Write 3 versions of this idea, each completely different and native to its platform:
1. A hook for a YouTube video.
2. The opening line of an Instagram Reel.
3. A hook for the first 3 seconds of a TikTok.

Rules: each version must feel natural on its own platform, never a copy of the others, and be ready for me to publish straight away.
