Hey Product Hunt! 👋 I’m the maker of Postfast — and I built it out of frustration with “generic AI writing”. Every platform has its own culture and unspoken rules. A post that works on X flops on Reddit. A Reddit post feels too long for Xiaohongshu. And AI tools today don’t understand that. So I wanted a tool that could: ✅ write native for each platform ✅ include your own products/brand ✅ save time without losing authenticity Would love your feedback, and I’m happy to take feature requests! If you have a product or personal brand, drop a comment — I’ll generate a custom post for you. 🚀
