THE TECH BEHIND REX™

What’s under the hood

Rex isn't magic (it just seems that way). Here's what powers autonomous bookkeeping:

Machine Learning Algorithms

Recognises patterns, classifies transactions, and improves accuracy over time.

Natural Language Processing (NLP)

Extracts key financial context from invoices, emails, and unstructured text.

Large Language Models (LLMs)

Understands transaction context and improves categorization with each interaction.

Proprietary OCR Technology

Reads invoices, receipts, and handwritten notes with pinpoint accuracy.

Integration APIs

Automatic data pulls from banks, suppliers, and financial platforms.

Human-in-the-Loop Verification

Finance experts review flagged items for an extra layer of precision.

Why Rex is better

Manual bookkeeping breaks down because it relies on humans doing repetitive work. Rex eliminates that dependency entirely.

Speed

Reliability

Cross-checked by AI, finance professionals, and built-in anomaly detection.
