The document layer for AI agents.

Paradoc enables AI agents to populate, validate, render, and reason over real-world documents. Deterministically, every time.

Documents as code

Testable. Type-safe. Portable. The building blocks code gives you, now for documents.

import { w9 } from "@paradoc/essentials/tax";
import { pdfRenderer } from "@paradoc/sdk";

const pdf = await w9
  .fill({
    parties: { taxpayer: { name: "Jane Q. Public" } },
    fields: {
      taxClassification: "individual_or_sole_proprietor",
      ssn: "123-45-6789",
      mailingAddress: { … },
    },
  })
  .render({ renderer: pdfRenderer(), layer: "pdf" });

The problem

Document infrastructure was painful even before AI.

The world runs on documentation. AI only amplifies the fragility and brittleness of traditional document infrastructure.

Rebuilt everywhere

Every app reimplements the same canonical forms.

Scattered infrastructure

Schemas, validation, rendering, and field mappings live across disconnected systems.

Inaccessible to agents

Context and code are trapped in backend systems, not machine readable to AI agents.

How Paradoc differs

One source of truth for software and agents.

One typed artifact. One SDK. Used by your code and your agents alike.

How it Works

Type-safe from definition to render.

import { para } from '@paradoc/sdk';

const lease = para
  .form()
  .name('lease-agreement')
  .parties({
    landlord: para.party().signature({ required: true }),
    tenant: para.party().signature({ required: true }),
  })
  .fields({
    address: para.field.address().required(),
    monthlyRent: para.field.money().required(),
    startDate: para.field.date().required(),
    endDate: para.field.date().required(),
  })
  .layers({
    markdown: para.layer.inline().mimeType('text/markdown'),
    // ...
  })
  .build();

Registry

Pre-built, production-grade artifacts.

Import instead of building from scratch. Forms, contracts, checklists, and bundles across tax, banking, healthcare, insurance, legal, and government.
