What it does
Multicalc is a free collection of simple, fast calculators for everyday use. It helps you make better decisions across finance, health, and daily planning — from SIP and EMI to BMI and basic calculations. No ads. No logins. No unnecessary complexity. Just clear numbers when you need them.
Practical online calculators for finance, math, and everyday planning.
Multicalc is your all-in-one hub for fast, practical, and free tools to simplify your daily decisions. BMI compares weight and height for a simple screening estimate; it does not diagnose health conditions or replace professional care. We now highlight short guidance pages for how to interpret EMI, BMI, and SIP results responsibly so the site feels more helpful and transparent. Get instant results with our optimized calculators. No waiting, no delays. Common formulas presented with transparent assumptions and usage notes. Most calculations run locally in the browser, and saved results are only kept when you choose to use account features. Responsive design that works perfectly on desktop,…from multicalc.in

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
