📌
Built after watching AI security get ignored, PromptShield is a solo-built firewall for LLMs — protecting your models from prompt injection, emoji attacks, jailbreaks, and token smuggling. It’s fast, affordable, and built for the future of AI. I’m proud to say this was built in India with zero funding — just mission, vision, and a lot of late nights.

This is such a fun and creative idea. Seeing the first versions of today’s biggest tech products is like a time machine for makers. I love that the community can refine and update them, and being able to duplicate and build your own version for free is a great bonus. Can’t wait to explore!
