Hey Product Hunt! 👋 I’m an indie developer, and I built NyxAstra because I wanted a more personal way to work with AI image generation. The part I care about most is Prompt Templates. When I find a prompt that works well, I can save it as a reusable template, tweak it, and build up my own library instead of starting from scratch every time. NyxAstra is native to Mac and iPad, supports your own OpenAI or Azure OpenAI API key, and keeps your prompts, history, and templates on your device. No account. No subscription. Just your models, your prompts, and your workflow. I’d love to hear how you use prompts and what you’d like to see in NyxAstra. 🚀
