Letterfork - Newsletter to 7 platforms in 60 seconds, in your voice.

Repurposing newsletters takes hours. Letterfork shrinks it to 60 seconds. Paste your Substack or Beehiiv link, and get 7 platform-native posts (LinkedIn, X, Bluesky, Threads, Reddit, etc.) generated in your exact tone. No generic ChatGPT speak. Our voice-cloning model learns your writing style. Outputs come pre-formatted with platform-specific rules (LinkedIn hooks, Bluesky chunks). One paste. Seven platforms. Your exact voice. Free to try, no CC required.

Hey Product Hunt 👋 I'm Super. Every time I hit publish on my Substack, I used to spend 3-4 painful hours rewriting the issue for LinkedIn, X, Bluesky, Threads, and Reddit. I tried ChatGPT and other repurposing tools, but they always made me sound like a generic brand account. So I built Letterfork. Just paste your newsletter link (Substack/Beehiiv/Ghost) and get 7 platform-native posts in 60 seconds. Instead of generic AI output, it analyzes your past writing to clone your actual voice—your rhythm, vocabulary, and quirks—and applies the unwritten formatting rules for each specific network. I’d love your brutal feedback today: 1. The Voice: Does the output actually sound like you? 2. The Weakest Link: Which platform's output needs the most work? (I'll fix it this week). 3. The Habit: What is missing that would make this a daily tool, not just a weekly one? You get 3 free lifetime rewrites to test it out (no CC required). I’ll be hanging out in the comments all day—bring it on! ☕️ — Super
