Hey Product Hunt 👋 I'm Madhavi, the maker behind CalcNest AI. The idea: most calculator sites bury simple math under ads, signup walls, or "premium" gates. I wanted a place where 456 calculators just work, instantly, for free, with no account. What's here: - 456 calculators across finance (132), health (90), math (74), daily life (160) including 30 pet calcs - 153 niche tools that are hard to find elsewhere: AI inference cost comparison, BRRRR real estate, yield farming APR, pet food portions, treadmill pace conversion - AI Finder — type a plain-English question, the right calculator opens - AI Concierge — multi-step scenarios where step 1's answer feeds step 2 (e.g., FIRE planning, home buying) - Editorial blog with peer-reviewed math frameworks What's NOT here: - Signups (zero) - Paywalls (zero) - Server-side tracking of your inputs (zero — math runs client-side, your numbers never leave your browser) I'd love your honest feedback — especially: (1) which calc is missing that you wish existed, (2) any calc that gave you a weird answer, (3) reactions to AI Finder and AI Concierge. I'll be here all day responding to every comment. Thanks for trying it ! --Madhavi
