// How to build AI Legal Document Drafting for Indian Startups & Freelancers
Indian startups spend ₹5,000–₹50,000 per document on legal fees. An AI that generates jurisdiction-correct documents (Indian Contract Act, Companies Act, FEMA) at ₹299/document or ₹1,499/month subscription is a strong wedge. Claude API excels at instruction-following needed for precise legal language. Digio provides legally-valid Aadhaar e-sign for Indian parties.

## What to build in the MVP
—Document type selector (NDA, employment, founder, rental, MOU, SLA)
—Guided questionnaire to capture parties, jurisdiction and key terms
—AI-generated document with clause-level explanations in plain English
—Track-changes redline mode for iterative editing
—Digio e-sign integration for legally binding execution
—Document vault with version history

## Engineering risks to plan for
!AI-generated legal documents carry liability risk — add prominent disclaimers and recommend lawyer review for high-value contracts.
!Indian law has state-specific stamp duty requirements; the document must instruct users on stamping, not just generate the text.
!Digio e-sign requires an API onboarding process that takes 2-3 weeks; initiate in parallel with development.
