modbender Prisma Gen
Stop hand-writing Prisma schemas. Just describe your data model in plain English and get a complete, production-ready schema.prisma file in seconds. No more googling relation syntax or forgetting @unique decorators.
One command. Zero config. Just works.
Quick Start
npx ai-prisma-gen "a blog with users, posts, comments, and tags"
What It Does
- Generates complete Prisma schema from natural language descriptions
- Handles relations automatically (one-to-many, many-to-many, self-referential)
- Adds proper indexes, constraints, and default values
- Supports all Prisma field types and decorators
- Outputs clean, formatted schema ready to use
Usage Examples
# E-commerce database
npx ai-prisma-gen "e-commerce with products, categories, orders, and user reviews"
# SaaS multi-tenant
npx ai-prisma-gen "multi-tenant saas with organizations, teams, users, and role-based permissions"
# Social app
npx ai-prisma-gen "social network with users, friendships, posts, likes, and direct messages"
# Save to file
npx ai-prisma-gen "task management with projects and assignees" > prisma/schema.prisma
Best Practices
- Be specific about relations - Say "users have many posts" instead of just "users and posts"
- Mention unique fields - Include "email should be unique" if that's what you need
- Include edge cases - Soft deletes, timestamps, status enums. Mention them upfront.
- Review before migrating - The schema is a starting point. Always check the output matches your needs.
When to Use This
- Starting a new project and need a database schema fast
- Prototyping an idea and don't want to waste time on boilerplate
- Learning Prisma and want to see how complex relations should look
- Converting a mental model into actual schema code

How It Works
Takes your plain English description, sends it to GPT with Prisma-specific prompting, and returns a properly formatted schema.prisma file. The AI understands Prisma conventions like @@index, @relation, and common patterns like soft deletes and timestamps.
