About

Hi!! I'm a solo, bootstrapped founder who loves building software I'd actually trust. Right now that's CalcFleet: 121 free calculators for money, home, fitness and AI economics — each a tested, source-cited formula, never an LLM guess. The twist: every calculator is also a JSON API and an MCP tool, so your software and your AI agents call the same math you do. No ads-first clutter, no signup. My ambition is bigger than a calculator site: as AI agents spread, they'll need a computation layer they can trust and call — I want CalcFleet to be it, with the free tools as the front door. I build fast, in the open, with AI as leverage. Spot a number that looks off? Tell me and I'll fix it — and I'd love to hear what calculator you wish existed.

CalcFleet - 120+ tested calculators, each also a JSON API and MCP tool

Most calculator sites are 90% ads and hide where the number came from. CalcFleet is the opposite: 121 calculators for money, home, fitness and AI economics, each a tested pure function — never an LLM guess — with sourced formulas and no signup. What stands out: every calculator is also a free MCP tool and a JSON API, so your apps and AI agents call the same math you do. The AI-economics tools (self-host vs API, RAG cost, agent cost per successful task) use dated snapshots of official prices.
