Signova — AI-Powered Legal Document Platform

getsignova.com · ebenova.dev · api.ebenova.dev

Signova generates professional legal documents, contracts, invoices, and compliance reports using AI — built for freelancers, agencies, and small businesses who need legal protection without lawyer fees.

Overview

Signova ships three surfaces from a single codebase:

• Consumer web app at getsignova.com — pay-per-document generation, promo redemption, buyer capture
• Developer platform at ebenova.dev + api.ebenova.dev — subscription API with keys, usage tracking, and Stripe billing
• MCP servers — Model Context Protocol servers that expose the same legal/insights/scope tooling to AI agents (Claude Desktop, Cursor, etc.)

The platform generates 34 document types (NDAs, contracts, offer letters, privacy policies, invoices, change orders, etc.) with jurisdiction-aware drafting for Canada (PIPEDA + Quebec Law 25), the United States (CCPA/CPRA + state privacy laws), the United Kingdom (UK GDPR), the European Union (GDPR), Nigeria (NDPA 2023), South Africa (POPIA), Kenya (DPA 2019), and Ghana (DPA 2012) — all with geo-aware currency detection and locale-specific drafting via Anthropic Claude.

Tech Stack

Features

Document generation

• 34 document types: NDA, freelance/service/consulting agreements, employment offer letters, privacy policy, terms of service, invoices, change orders, scope analysis, and more
• Jurisdiction-aware drafting across Canada, USA (with state-level awareness), UK, EU, Nigeria, South Africa, Kenya, and Ghana
• Free Groq-powered preview (api/generate-preview.js), premium Claude output on payment verification (api/generate.js, api/v1/documents/generate.js)
• Conversation-to-document extraction (api/v1/extract/conversation.js)

Promo system

Promo codes bypass payment to unlock one free document. State is stored in Upstash Redis (promo_uses:CODE counters, promo_ratelimit:IP per-IP hourly limiter). IP rate limit: 5 attempts/hour. All codes defined in api/promo-redeem.js.

Billing (Stripe)

• Consumer pay-per-document checkout (api/stripe-checkout.js, api/stripe-verify.js, api/stripe-webhook.js)
• Subscription plans for the API: Starter $29, Growth $79, Scale $199 (api/v1/billing/checkout.js)
• Insights add-on plans: Starter $49, Growth $99, Scale $249 — activated commercial feature
• Stripe Customer Portal (api/v1/billing/portal.js), webhook handler (api/v1/billing/webhook.js)
• Scope Guard Pro checkout (api/scope-guard-checkout.js) — activated commercial feature

MCP servers

Three first-party MCP servers live under mcp-servers/:

Each has its own package.json, server.json, and Dockerfile, and publishes independently to npm / the MCP registry / Smithery / Glama.

The site itself also exposes an HTTP MCP endpoint at api/mcp.js.

API authentication

Authenticated endpoints under /v1/* use two distinct credentials:

1. Bearer API keys (Authorization: Bearer sk_live_...) — end-user keys validated against Upstash Redis via lib/api-auth.js. Used for document generation, extract, scope, vigil, contracts, insights, invoices.
2. Admin/setup secret (EBENOVA_ADMIN_SECRET) — gates /v1/keys/create so only operators can provision new customer keys. ADMIN_API_TOKEN similarly gates /v1/admin/revenue. BYPASS_ADMIN_SECRET gates api/create-bypass.js. CRON_SECRET / POLL_CRON_SECRET authenticate Vercel cron invocations.

Rate limits and monthly document caps are enforced per key in Redis.

Note: there is no live /docs HTML endpoint today. Consume the OpenAPI spec directly via openapi.yaml.

Local development

Prerequisites

• Node.js 20+ (ESM)
• Upstash Redis database (free tier)
• Anthropic API key
• Stripe account (only needed to exercise paid flows)
• Resend API key (optional, for email)

Setup

git clone <repo-url>
cd signova
npm install
cp .env.example .env
# edit .env with your keys

Scripts

npm run dev            # Vite dev server
npm run build          # Production build
npm run preview        # Preview built SPA
npm run lint           # ESLint
npm test               # Vitest
npm run test:coverage  # Vitest with coverage
npm run check:css      # Validate CSS design tokens
npm run keygen         # Generate API/admin secrets

Running the serverless api/ functions locally requires the Vercel CLI:

npm i -g vercel
vercel dev

Environment variables

See .env.example for the full template.

Required (core)

Stripe (required for paid flows)

Optional (email, alt-payments, misc)

Admin, cron, integrations (optional)

Deployment

The project is deployed on Vercel:

• Project: signova
• Owner: ebenovasolu-5755s-projects
• Domains routed via vercel.json redirects: apex getsignova.com → www.getsignova.com, apex ebenova.dev → www.ebenova.dev
• Cron jobs configured in vercel.json

vercel          # preview deploy
vercel --prod   # production deploy

Configure environment variables in Vercel → Project Settings → Environment Variables (mirror the list above).

Testing

Current status — be honest about what ships vs. what is planned:

Run with npm test (Vitest). npm run test:coverage emits a v8 coverage report.
