How I built an AI tool that repurposes any URL into 4 social formats in 60 seconds

Every time I finished writing an article, I faced the same problem.

I had to spend another 2-3 hours turning it into a LinkedIn post,
a Twitter thread, a newsletter, a TikTok script — each with a
completely different tone and format.

So I built UseRepurposer.

How it works

Paste any URL or text → get 4 formats simultaneously in under 60 seconds:

  • LinkedIn post — proper hooks, optimized length, ready to post
  • Twitter/X thread — numbered, engaging, platform-native
  • Newsletter section — intro + body, ready to send
  • TikTok script — hook + talking points
  • Export all 4 formats at once with one click

No prompting. No editing. Just paste and post.

Tech stack

  • Frontend: React + TypeScript, Tailwind, Redux Toolkit, RTK Query
  • Backend: Node.js + Express, TypeScript
  • AI: Groq API with llama-3.3-70b (insanely fast — 1-2s vs 8-12s with OpenAI)
  • Database: Supabase (PostgreSQL)
  • Payments: Stripe
  • Email: Resend
  • Hosting: Render + custom domain

Why Groq over OpenAI?

Speed was everything for this use case. Users paste content and
expect results immediately — not in 10 seconds.

Groq + llama-3.3-70b gives me 1-2 second generation time
vs 8-12 seconds with GPT-4o. For perceived quality, this was a game changer.
