JanVayu

Air quality data in India is abundant and mostly unusable: raw numbers with no answer to what a resident should do today, or who is answerable for the reading being what it is.

JanVayu pairs an ask-anything interface with a health advisory and an accountability brief, so the same reading tells you how to protect yourself and where the responsibility sits. An easy mode keeps technical explanations approachable, and the full tech stack is documented in a public GitBook.
