Why now

TypeScript's growing complexity creates demand for tools that handle tricky type situations like preserving narrowing.

Who for
TypeScript developers
Business model
Pro version sales
Effort
A few weeks

Developers waste time writing and debugging complex type guards.

Build a VS Code extension that analyzes interfaces and generates optimized guard functions.

Monetize through Pro features like custom guard templates and team sharing.

MVP would handle basic interface-to-guard conversion.

Risk is TypeScript changing its compiler behavior.
