A mobile-first personal finance and document management application that helps users scan, categorize, organize and report financial records and documents with AI assistance.
01
Project Overview
- Paiperworks combines personal finance management and document organization in one product.
- The mobile app supports daily entry, while the web app focuses on bulk operations, reporting and import-export workflows.
02
The Problem
- Financial records and documents can be scattered across applications, folders and physical sources.
- Manual entry, categorization and retrieving historical information can take time.
03
The Solution
- Images and PDFs are analyzed with OCR and AI, then reviewed and edited by the user.
- Documents and financial records can be connected with accounts, folders and categories.

Technical Challenges
Reliable AI results
An editable preview flow keeps results reliable across varying document structures.
