About

my name is Jai. I like building useful things. Currently, I'm spending the majority of my time building HireNewTalent.ai (see below) while running the largest driving school in the SF Bay Area. Along the way, I've discovered several burning problems that I've solved through projects (some paid some free). CEO @ Bay Cities Driving School (largest driving school in the Bay Area) Founder/CEO @ HireNewTalent.ai (making offshore hiring easy for all) Other Projects: ReadySetReview.ai (solicit and automatically respond to Google Reviews) SecurePrompt.dev (sanitize LLM input/output instantly) CaratRank.com (compare diamond prices across major retailers)

CaratRank - The lowest price on any diamond

We search 20+ diamond retailers to show you the cheapest listings for any specific diamond. Many times, retailers mark diamonds up by 10x vs. wholesale prices, and we're the only site that can show you where to find the best deals. We match stones by IGI, GIA, or GCAL certificate and allow you to search by style or by certificate number (which isn't a feature any retailer offers). Furthermore, we're unbiased: we don't take any referral fees from anyone.
