About PaperBrain
What is PaperBrain?
PaperBrain is an AI-powered invoice processing platform that reads invoices in any format—PDFs, scans, photos—and extracts clean, structured data with 98% accuracy. It eliminates manual data entry and spreadsheet typing, turning messy invoices into organized, validated data in about 45 seconds per document.
Who is it for?
PaperBrain is built for finance teams, small business owners, and accountants who handle high volumes of vendor bills and need accurate, fast data extraction. It’s ideal for businesses dealing with multi-currency invoices and GST compliance (India-focused but supports 50+ currencies). It is not for teams that need full accounts payable automation beyond data extraction.
Real use cases
Use PaperBrain to process vendor invoices at month-end, extract line items and totals from blurry photos or WhatsApp screenshots, validate GSTIN, and export data to Excel, CSV, JSON, or API. It supports batch uploads (up to 100 files at a time) and integrates with your existing tools via export options.
Key features
- AI-Powered Extraction — Automatically reads invoice fields like vendor, invoice number, date, totals, and tax breakdowns.
- Multi-Currency Support — Auto-detects and converts 50+ currencies with real-time rates.
- GST Compliance — Full tax breakdown with GSTIN validation (CGST/SGST).
- Batch Upload — Process hundreds of invoices at once with a single upload.
- Export Any Format — One-click export to XLSX, CSV, JSON, or API.
- Bank-Grade Security — 256-bit encryption and SOC 2 compliance, no data stored.
