Automated Document-to-Text Conversion with NAN System

This system addresses the challenge of manually entering data from images and PDF documents into applications like Google Sheets and QuickBooks. The core functionality revolves around automating this process using Artificial Intelligence (AI). The primary method of initiating the workflow is through uploading documents to Telegram.

Workflow Process

The process unfolds in a step-by-step manner:

1. Document Upload: A user uploads a document (PDF, image, video, audio, Google Slides, Sheets, or Docs) to Telegram.
2. Workflow Trigger: The “NAN workflow” automatically receives the uploaded document.
3. AI-Powered Extraction: The system employs AI to extract relevant data, specifically focusing on “line items” and associated pricing.
4. Data Integration: The extracted data is automatically populated into Google Sheets.

Examples & Data Accuracy

The video showcases two specific examples to demonstrate the system’s capabilities:

• Image Receipt: A receipt containing four line items, priced between $19.99 and $24.99, was successfully processed. The system accurately extracted the individual prices, confirming data fidelity.
• PDF Invoice: A PDF invoice with a subtotal of $85 was processed, and the system correctly identified and extracted this value.

These examples highlight the system’s ability to handle varying document formats and accurately capture numerical data. The visual comparison between the original document and the extracted data in Google Sheets confirms the accuracy of the extraction.

Document Versatility

A key advantage of the NAN system is its versatility. It’s not limited to just images and PDFs; it can also process data from:

• Videos
• Audio Files
