Hey Product Hunt! 👋 I'm excited to share Reply Better AI, a project born from my own need for quick, professional writing improvements. As a developer working with international clients, I often found myself spending too much time perfecting emails and messages. 🎯 What makes it different: • Completely free - just bring your OpenRouter API key • Privacy-focused and open source • Works everywhere - Gmail, Twitter, LinkedIn, etc. • Custom prompts for your specific needs I've just updated it with powerful new AI models (DeepSeek V3, Gemini Pro) for even better results. 🎁 For Product Hunters: I'd love your feedback! Try creating custom prompts for your specific needs or using snippets for quick responses. Let me know what you think! Check out the demo video to see it in action, and feel free to ask any questions. I'll be here all day to respond!
