Letterfork とは？

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.
