Our products
ChatKhata
Order kahin se bhi aaye, khata khud bane.
An AI order-book for India's small chat-commerce sellers — boutiques, cloud kitchens, home businesses doing 10–20 orders a day over messaging. Incoming order messages become confirmed order cards and a live payment ledger (khata) automatically. Sellers just tap to confirm.
- ✓Connects to WhatsApp Business via the official Meta Coexistence API
- ✓AI parses who / what / how much / where from plain chat
- ✓Two ticks per order: Sent · Payment received
- ✓Free for the first 15 orders a month, then ₹299/month
CODENAME
Personalised leather flying jackets, made in India.
A direct-to-consumer label for hand-finished leather flying jackets with a personal callsign. Customers reserve online with a ₹499 booking token; the rest is paid on dispatch. Payments run on Razorpay with automated booking references and webhooks.
- ✓Next.js storefront with one-click Razorpay checkout
- ✓Automated booking references (CDN-XXXX) and paid-status webhooks
- ✓Supabase order ledger · Vercel hosting
