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.
