Every winter, North India is engulfed in a blanket of smog, bringing attention to the severe air quality crisis plaguing the region. Cities like Delhi consistently rank among the most polluted globally, with PM2.5 levels soaring far above safe limits. The health impact is devastating—causing respiratory ailments, cardiovascular diseases, and even premature deaths. According to estimates, air pollution claims over 6.7 million lives annually worldwide, with India bearing a significant share of this burden.

While government agencies provide air quality data, the raw numbers often remain incomprehensible to the public. The question remains: How do we translate this information into actionable insights for ordinary people?

Enter VayuBuddy, a breakthrough chatbot developed by researchers at IIT Gandhinagar and collaborators. Designed to make air quality data accessible to everyone, this Large Language Model (LLM)-powered tool simplifies complex datasets into comprehensible insights.

What is VayuBuddy?
VayuBuddy leverages artificial intelligence to respond to natural language queries about air quality. For example, users can ask questions like, “What were the pollution levels in my city last month?” or “Which cities are the cleanest in winter?” The chatbot processes the query, analyses data from India’s Central Pollution Control Board (CPCB), and delivers answers in plain language or through visualisations like graphs and heatmaps.

“Our aim was to reduce the gap between raw data and public understanding,” says Prof Nipun Batra, a lead researcher on the project. He adds, “VayuBuddy gives people a way to interact with air quality data in a user-friendly manner, empowering them to make informed decisions.”

Why VayuBuddy Matters: Air pollution doesn’t just harm the lungs; it infiltrates every aspect of life. From children missing school due to health issues to reduced workplace productivity, the ripple effects are vast. Yet, the lack of accessible tools prevents communities from fully grasping the severity of the problem or holding polluters accountable.

Dr Sarath Guttikunda, air quality expert and collaborator, highlights the broader implications: “Air pollution is a shared challenge, and tools like VayuBuddy can foster collective awareness and action. When people see clear, localised data, they’re more likely to advocate for cleaner policies.”

Making Data Meaningful: VayuBuddy stands out for its ability to generate insights tailored to various stakeholders. Policymakers can track compliance with air quality standards, parents can evaluate their children’s exposure, and journalists can report trends using ready-to-publish charts.

Zeel Patel, one of the researchers, underscores the versatility of the tool: “By combining data analysis with AI-powered conversations, VayuBuddy opens up new possibilities for engaging with air quality data. It’s designed to work for everyone, not just experts.”

Looking Ahead: The team behind VayuBuddy is already planning its next steps. Expanding its capabilities to cover more pollutants like NO2 and ozone, integrating multilingual features, and incorporating datasets from other countries are all on the horizon.

Even as they pursue these ambitions, the researchers remain focused on the core mission: making air quality insights accessible, actionable, and impactful.

A Cleaner Tomorrow – The fight against air pollution is a collective endeavor, and tools like VayuBuddy are empowering individuals and communities to play their part.

As Dr. Guttikunda aptly says, “By transforming complex data into actionable insights, VayuBuddy has the potential to drive meaningful change, one conversation at a time.”

With innovations like VayuBuddy, the hope for a cleaner, healthier future seems slightly brighter.
