Project Summary

Date: Nov 2024
Description: AI-powered domain name generator SaaS. Users describe their business idea, and the app uses Google Gemini to generate unique, brandable name suggestions (neologisms with suffixes), then checks real-time WHOIS availability across .com, .ai, .io, .co TLDs.
