We built ViviGener, a free community platform where anyone can discover, share, and contribute AI prompt templates for various models like Nano Banana, ChatGPT, Midjourney, and Stable Diffusion.

The Problem: Most valuable prompts are scattered across Reddit threads, Discord servers, Twitter posts, and private notes. There's no centralized place where the community can build and maintain a high-quality prompt library together.

What We Offer: • Searchable Library: Browse curated AI prompts organized by use case, category, and AI model - completely free • Easy Submission: Anyone can submit their best prompts and help others achieve better results • Community Discussion: Comment on prompts, share tips, and learn from others' experiences • Organized Collections: Bookmark your favorite prompts and build personal collections for quick access • Proper Attribution: Give credit to original creators when submitting existing prompts

We're running on Cloudflare infrastructure, making it fast and globally accessible. The platform is entirely free to use - no paywalls, no premium tiers.

If you've created effective prompts or discovered great ones, we'd love for you to share them on ViviGener. Every submission helps build a better resource for the entire AI community. Whether it's a creative writing prompt, a code generation template, or an image generation recipe - your contribution matters.

We're actively looking for early contributors to help build the initial library. The platform is young and your submissions will have high visibility.
