How It Works

Three steps to a PDF

Describe what you need in plain language. The AI generates a structured JSON spec constrained to our component catalog. React-PDF renders it to a downloadable file.

1

Describe

Tell the API what you need: "Create an invoice for 5 hours consulting at $200/hr for Acme Corp"

json-render + react-pdf renders the spec server-side. You get a real PDF file — no browser, no puppeteer

Motion Signatures

Animated signatures for documents

Powered by ve-animesign-pdf — render handwritten signature animations as PNG, MP4, or GIF, then embed them into your generated PDFs.

Output Formats

Render signatures as static images for PDFs, animated loops for web previews, or shareable GIFs for messaging.

PNG MP4 GIF

Customizable

Control signature color, background, padding, fade-in frames, and dimensions. Each signature gets a unique pen-writing animation.

Runtime Integration

SignatureRuntimeClient connects to the ve-animesign-pdf service with auto-retry (2x) and configurable timeout (default 120s).

PDF Embedding

Rendered signatures become Image components in the json-render spec. Works with contracts, invoices, letters, and any document type.
