What's being built
right now
Each upcoming tool targets a real gap in the Indian market — problems that affect millions of people daily but have no good, India-specific solution yet.
Building
Freelancers
Invoice Chaser
Auto-follow up on overdue payments via WhatsApp and email — with the right tone and ₹+GST context. Indian freelancers lose crores chasing late payments.

Planned
Small Businesses
GST & Tax Explainer

WhatsApp Reply Generator
Indian shop owners manage hundreds of WhatsApp messages daily. Generate polite, professional replies in seconds — in English, Hindi, or Kannada.

Legal Notice Writer
Draft consumer complaints, RTI requests, and landlord notices in proper legal language — in seconds. Lawyers charge ₹2000+. One tool can do it in 30 sec.
