Hey Product Hunt! 👋 I built ContentMill because I was tired of the "content repurposing" workflow that every creator knows: 1) Write a great blog post 2) Open LinkedIn, stare at the blank post box, try to condense 1,500 words into 1,200 characters 3) Open Twitter, figure out how to thread it 4) Open your email tool, write yet another version 5) Realize you just spent 2 hours on distribution instead of creating ContentMill does steps 2-4 in about 45 seconds. But here's what makes it different from other AI writing tools: It doesn't just generate text — it publishes directly. Connect your LinkedIn and Twitter accounts, and you can post with one click. No copy-pasting between tabs. Other things I shipped that matter: - URL input — paste a blog URL and ContentMill extracts the article. No copy-pasting your whole post. - Referral program — invite a friend, you both get 5 bonus repurposes. No cap. - Platform-specific formatting — LinkedIn hooks, proper Twitter thread numbering, newsletter subject lines. Baked in, not prompted. The free tier gives you 5 repurposes/month — no credit card required. 🎉 Product Hunt exclusive: 20% off Pro for your first month ($23.20 instead of $29). Valid launch week only. I'm the solo maker here — would love your feedback on what platforms or features to add next. Direct publishing to more platforms? Scheduling? Something else? Happy to answer any questions! 🚀
