Show HN: RepackAI – Turn long-form content into platform-native social posts
Client-side tool that takes long-form content and generates platform-specific versions for Twitter/X, LinkedIn, Instagram, and email newsletters. Pure frontend, BYOK (bring your own key), content never leaves the browser. Single HTML file, no build step.
Two things I've learned building in this space: (1) voice consistency across platforms is harder than the actual generation — LinkedIn tone vs. email tone vs. X tone all need different sentence structures, not just length adjustments. (2) The real retention driver is showing users the before/after quality gap between generic repurposing and platform-tuned output.
Curious how you're handling voice drift across formats. That's been my biggest engineering challenge.
