Saans (सांस, "breath") is a real-time air quality intelligence platform that helps people understand pollution, spot risk and decide what to do. It combines live station data from OpenAQ and WAQI with CAMS model forecasts, and makes the provenance of every number visible: measured, modelled, forecast, computed or machine-learning predicted, with source, observation time and station distance. Users get a live dashboard, an interactive map with heatmap and hotspots, historical comparisons with spike detection, side-by-side city comparison, health guidance and a five-day forecast with a best-time-to-go-out planner. Bonus tools include a grounded AI assistant with voice, smart alerts, shareable cards, printable impact reports, a city leaderboard, an experimental ML model that openly reports when it fails to beat simple baselines, and a Diwali air check comparing measured and modelled data. It degrades gracefully when any source fails and never presents modelled data as measured.
