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.

07

Technical Challenges

Reliable AI results

An editable preview flow keeps results reliable across varying document structures.

08

Key Decisions

  • AI output does not directly create a final record.
  • Mobile and web experiences are differentiated by their usage goals instead of sharing one interface.

09

Outcome
