What's on InnoviCat
InnoviCat is a free, privacy-first platform with practical tools organized into three sections. Everything runs in your browser—no accounts, no uploads, no tracking.
Practical Tools
From productivity timers to PDF editors, text utilities to image processors—tools designed to help you get things done.
- Cooking (18) — Kitchen converters, baking calculators & food planning tools
- Decisions (9) — Tools for thinking a decision through — explore a fuzzy situation, weigh your options, separate facts from assumptions, and track the outcome.
- Developer (19) — Code formatting, encoding, and debugging utilities
- Engineering (21) — Engineering calculators across three areas: HVAC, electrical, and measurement. The HVAC tools run the full residential design pipeline — insulation R-value against IECC 2021, heating and cooling loads per ACCA Manual J, equipment sizing per Manual S, room airflow, and duct sizing with ASHRAE and SMACNA methods. The electrical tools are built on the US NEC — conductor ampacity and wire size, voltage drop, conduit and box fill, and dwelling service load. Measurement tools convert decimal feet and calculate with feet, inches, fractions, area, and perimeter. Everything runs locally in your browser.
