Stencilry

Free during beta

HTML goes in. A real PDF comes out.

Write a document as HTML, hand it a JSON payload, and watch the real PDF redraw as you type, or have your AI assistant design it for you. No pricing yet: it's on us while we're in beta.

How it works

You, in the editor

1 · Template

<h1>Invoice {{ number }}</h1>
<p>{{ customer }}</p>

HTML and Liquid.

2 · Payload

{
"number": "NW-0481",
"customer": "Harbour & Vale"
}

JSON data to fill it.

Or your AI agent, over MCP

1 · Template

› Make an A4 invoice template for Northwind.

● Checked page 1. Saved.

It writes it and checks each page.

2 · Payload

› Add a sample customer and three lines.

● Sample payload added.

It adds data to test with.

3 · API call

POST
/templates/{id}
/generate
{ "payloadJson" }

Your system sends its JSON.

4 · PDF

The real PDF.

Template, data and PDF, side by side.

Change the HTML or the JSON and the real PDF redraws a moment later.

The Stencilry Playground: the invoice template, its JSON payload and the rendered PDF side by side.

Design it once. Generate it forever.

Build a template like an invoice or a shipping label, then call it from your own systems over the API: same renderer, no re-authoring, every time it fires.

For AI agents

Your agent builds it. Then it checks the pages.

Connect via MCP, describe your document, and let your AI agent write, check, fix, and save it.

Works with Claude Code, Cursor, Codex and GitHub Copilot.
