How to build Document Analysis & Data Extraction (OCR + AI) with AI
Reads uploaded documents and pulls out the important fields automatically. Staff type data from invoices, forms, or IDs into systems by hand. With an AI vibe coding tool, a first working version typically takes 2–3 weeks when you plan it first, build one part at a time, and test each step.
What it's made of
- Upload screen
- OCR: reading text from scans and photos
- AI that maps text into fields
- Human review screen for low-confidence results
- Export or save to the database
How to build Document Analysis & Data Extraction step by step
- Plan before building. Ask the AI builder for a written plan: every screen, the database tables, who logs in, and outside services. Approve it first.
- Build the foundation. Main screens, navigation and database tables, mobile-first.
- Build: Upload screen. Connect it to what exists, validate input on the server, and test it.
- Build: OCR: reading text from scans and photos. Connect it to what exists, validate input on the server, and test it.
- Build: AI that maps text into fields. Connect it to what exists, validate input on the server, and test it.
- Build: Human review screen for low-confidence results. Connect it to what exists, validate input on the server, and test it.
- Build: Export or save to the database. Connect it to what exists, validate input on the server, and test it.
- Lock it down. Logins, server-side permissions, validation and rate limits. No secret keys in page code.
- Polish and launch. Speed, a 404 page, policies, backups, HTTPS and a rollback plan.
