Capabilities

Everything you need to build document workflows

REST API

Generate PDFs programmatically. Pass a template ID and your JSON data payload — get a rendered PDF back in milliseconds. Works with any language and any stack.

View API docs

Data binding

Connect templates to JSON schemas. Define dynamic variables, pass sample data, and render documents that adapt to any payload.

120+ starter templates

Invoice, report, certificate, receipt, letter — pick a template and customize it. Ship documents in minutes, not days.

Chat-driven design

Describe what you want in plain English and the AI assistant helps you edit your template in real time. Or import a .docx and start from there.

LIVE

Live preview

See your PDF update as you edit. Changes render instantly in the browser — no waiting, no round-trips.

Pixel-perfect output

Crisp, print-ready PDFs with precise typography, layout control, and consistent results — every render, every time.

Version control

Every edit is tracked. Roll back to any checkpoint, compare versions side-by-side, and branch templates confidently.

MCP support

Connect any AI agent to PDF generation via the Model Context Protocol. Let Claude, GPT-4, or your own LLM render documents as a native tool.

Team workspaces

Organize templates by team. Share styles, fonts, and brand assets across your organization with role-based access.
