Hissab

什么是 Hissab？

Hissab is a strict, unit-aware natural-language calculator. Type real-world math - units, dates, finance, percentages, IP/CIDR, matrices, symbolic algebra and get exact, auditable answers. One engine runs across the web/PWA app, Chrome extension, CLI, embeddable npm library, and hosted MCP server that AI agents can call instead of guessing. Now open-source.
