MarketMate turns a market seller's spoken prices into a checked, shareable price list in minutes instead of an hour or more with chalk.

Every morning, vegetable and fruit sellers in Tamil Nadu buy at the wholesale market, then spend 1 to 1½ hours writing prices on slates. Two real sellers in our video, AK (A.V. Market, Padappai) and VPS (Urapakkam), say this on camera, and VPS's shop page is live on MarketMate today.

The seller films the stall and says today's prices in Tamil (voice input takes 25 languages). Muse Voice Transcribe turns the speech into timed text, Muse Spark extracts every item, price and unit and checks each one against the seller's own words, and SAM 3.1 finds each item in the video so every price gets a real photo. Nothing is guessed: unclear or sound-alike numbers, missing units and prices with no item are flagged for one tap, and every price plays back the exact second it was said.

After approval the list becomes a live shop page and a WhatsApp catalog. Customers order without installing an app, and the same list runs bills (cash/UPI/credit), the day close and an Excel sheet. A Meta AI calls page logs every call with model, time and cost (VPS's 64-second video: 96 calls, $0.36).

Judges: open the live site https://sivat241--marketmate-web.modal.run and pick "Judge demo" to run your own stall video or VPS's real sample, and get a price card, WhatsApp catalog and Excel sheet in about 3 minutes.
