Silverhold Post: Format your video posts for every platform, from one prompt

Hey Product Hunt 👋 I built Silverhold Post because I kept spending 20+ minutes after every video export just rewriting the same title/description into 6 different formats for YouTube, TikTok, Instagram, Facebook, X, and Pinterest — each with its own rules for hashtags, character limits, alt text, and boards. Silverhold Post takes one description and instantly formats it correctly for all six. There's a free offline mode that works with zero setup, and an optional mode where you connect your own AI key for freshly generated content each time. It's a one-time $24 purchase, no subscription, works fully offline if you use the free mode. Built it entirely solo — would love any feedback, especially on which platform's formatting rules I should refine next.
