Hello PH! 👋 Meet PromptFill: The Open-Source Prompt Manager for Creators Hello everyone! I'm Mario, the founder of Corner Studio. As an architect and AI product manager, I spend my life navigating between aesthetic design and complex prompt engineering. Like many of you, I found myself drowning in messy Notion pages, TXT files, and endless copy-pasting just to manage my prompts for Midjourney, ChatGPT, and Stable Diffusion. That’s why I built PromptFill. It started as a small tool to scratch my own itch, but to my surprise, the open-source community loved it—we just hit 1.3k+ stars on GitHub! 🚀 What makes PromptFill different? Variable-First: Stop editing long strings manually. Use placeholders and fill them in seconds. Open Source & Privacy: No cloud lock-in. It’s your data, your workflow. Built for Speed: A clean, minimal UI that stays out of your way. We’re launching on PH today because I want to hear from this community—the most demanding and creative users on the web. I’d love to know: How do you currently manage your "Golden Prompts"? What feature would make PromptFill a "must-have" in your daily AI workflow? I’ll be here all day to answer your questions and chat about the future of Prompt Engineering. If you like what we're building, your support and feedback would mean the world to us! Happy Prompting! 🎨🤖
