BadaBhai brings practical AI to an ordinary phone. No app is required. Dial +91 79 4850 4917, ask in Hindi or English, and hear a short answer. India numbers start in Hindi. Others start in English. Press 1 for what the call can do, 2 for English, 3 for Hindi, or 9 to interrupt.

Built for the Meta Global AI Developer Hackathon, consumer access. The demo is a normal Exotel phone call, so a feature phone can use it. Meta Muse Voice Transcribe hears the caller. Muse Spark 1.3 answers. An Indian voice speaks back. Everyday replies stay short. A question about a public office, address, or phone number uses the same model with Meta web search, and the voice says only what that search found. The call does not invent a number, decide eligibility, or ask for Aadhaar, an OTP, or account details.

Judges: open https://badabhai.shreejientserv.in/dashboard, then call. Words and timings appear only while the call is open. Phone numbers stay hidden. Nothing is saved. One call at a time. The free line ends after about three and a half minutes, so ask early. It is not toll-free. If the line is down, use /backup-demo. The trial number may stop around 9 November 2026. From a US landline, dial 011 91 79 4850 4917. For more information about this project and future plans and potential application of this solution please visit https://badabhai.shreejientserv.in

Site path: the home page has the 90-second walkthrough. /how-it-works is today's proof of concept. /future#impact is the next step, starting with nearby public job posts, and that helper is not on the call today. /commitment pledges half of any prize to a Rajkot and Ahmedabad pilot, official-source scheme explainers, and MCA and BTech interns. /architecture is how it is built with Meta. This is an independent prototype, not a Meta or government service. Code: https://github.com/naimishkathrani-web/BadaBhai
