AI Contract & Document Generator — React + OpenAI + PDF
Your clients answer a few questions in a friendly chat interface. Our AI fills in the blanks, populates your legal template, and delivers a perfectly formatted, downloadable PDF — in under two minutes. No lawyers, no copy-paste, no errors.
Build My Document GeneratorWhat We Build
A full-stack document automation application that removes the manual effort from contract creation. Whether you're a real estate agent, consultant, freelancer, or SaaS company, we build a generator that matches your exact template and brand.
AI Chat Interview (React Frontend)
A clean React chat UI guides users through a series of dynamic questions — adapting follow-up questions based on previous answers. The interface is branded to match your business and works on any device.
OpenAI-Powered Field Extraction
GPT-4o parses conversational answers and extracts structured data — names, dates, addresses, monetary values, clauses — with high accuracy. We engineer the prompts to match your document's specific field requirements.
Node.js Backend & Template Engine
The Node.js backend receives extracted data, merges it with your document template, and generates a PDF using PDFKit or Puppeteer (HTML-to-PDF). Supports multi-page documents, tables, signature blocks, and custom styling.
Instant PDF Download
The finished document is returned as a downloadable PDF in seconds. We also support email delivery via SendGrid and file storage to AWS S3 or Google Drive for record keeping.
DocuSign E-Signature Stub
We include a DocuSign API integration stub that sends the generated PDF to all signatories for electronic signature. Full sandbox testing and production activation are available as an add-on deliverable.
Our Development Process
1. Template Analysis
We review your existing contract or document, identify every variable field, and map the question flow that will populate them.
2. Prompt & Schema Design
We design the OpenAI system prompt and JSON output schema to extract every field reliably from natural-language answers.
3. Frontend Build (React)
Build the chat interface with progress indicators, validation, and a preview pane so users can review before generating.
4. Backend & PDF Engine
Build the Node.js API, integrate OpenAI, implement the PDF template, and wire up storage and email delivery.
5. QA, DocuSign & Deployment
End-to-end testing across document types, DocuSign sandbox test, and deployment to Vercel, Railway, or your server.
