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. 🚀

Hey Product Hunt 👋
I’m the maker of PostFast — thank you for checking us out today.

I built this because I was tired of the same loop: switching between ChatGPT and social platforms, rewriting prompts, and still getting generic content that didn’t sound like my product.

PostFast is our answer: a context-first growth engine for creators and indie hackers.

What’s new in this version:

🧠 Context-First AI: combines your product facts + reference styles + platform context
🐦 Native X reply workflow: generate and inject replies directly in-page
📌 Viral content capture: collect inspiration and reuse it as structured context
🔗 Extension + SaaS loop: create fast in browser, manage deeper workflows in web app

If you create content for growth, I’d love your feedback:
What part of your workflow is still the most painful today?
I’ll be around all day replying and shipping improvements 🙌
