Application data
Pass structured values from your product or agent. Templates and content stay in your codebase.
PLATFORM / ARCHITECTURE
A document runtime between model output and customer delivery.
PaperJSX turns structured application data into native documents inside the execution boundary you control.
Runtime architecture and ownership.
Local rendering
Run TypeScript packages inside your application process.
Native format
Return an office file or fixed-layout PDF.
Verification assets
Pair output with repeatable fixture, fidelity, and visual regression checks.
Return failures to the calling application.
Validation and diagnostics remain observable at the runtime boundary.
Render a file from your own JSON.
The playground runs the same engines as the packages.
