Generate documents from templates, extract data with AI, and collect legally binding signatures. No compliance headaches.
Platform
Create documents from reusable templates with dynamic merge fields. Populate with data from your systems via API. Support for bulk generation from CSV or JSON.
AI-powered field detection reads any PDF and returns structured data. OCR for scanned documents. Pre-built schemas for invoices, contracts, and tax forms.
Legally binding digital signatures with RFC 3161 timestamps. Multi-signer workflows with sequential ordering. Complete audit trails and certificates of completion.
For developers
Install the SDK, create a document, and send it for signing. The entire flow takes five lines of TypeScript. Webhooks notify you when signers complete their fields.
npm install @korala/sdkkorala.documents.create({ ... })document.completed → your callbackimport Korala from "@korala/sdk";
const korala = new Korala({ apiKey: process.env.KORALA_KEY });
// Create a document from a template and send for signing
const document = await korala.documents.create({
templateId: "tmpl_nda_2024",
data: {
clientName: "Acme Corp",
effectiveDate: "2024-03-15",
},
signers: [
{ name: "Jane Smith", email: "[email protected]", role: "client" },
{ name: "John Doe", email: "[email protected]", role: "sender" },
],
});
// Document is sent — signers receive email notifications
console.log(document.id); // "doc_a1b2c3d4"
console.log(document.status); // "pending"Trust & Security
Every signature includes a cryptographic certificate and RFC 3161 timestamp. Every action is logged in an immutable audit trail.
Platform-issued certificates backed by a trusted CA chain.
DigiCert TSA provides long-term validity proof for every signature.
Every view, sign, and download is logged with IP, timestamp, and user agent.
Data processing agreements, EU hosting options, and right-to-erasure support.
Integration
RESTful API with HMAC authentication. TypeScript SDK with full type safety. Webhooks for real-time event notifications. Embeddable React components for signing UIs.
Use Korala for straightforward signing, or pay for API platform usage across documents, fills, signing, and orchestration.
