Building a Privacy-First Expense Sorter with Open-Source AI for Freelancers

说明与用途

LedgerShield 是一个本地化的工具，自动提取并分类收据数据，保护隐私并为自由职业者节省时间。

问题

Freelancers need automated bookkeeping without exposing sensitive financial records to third‑party cloud services.

结果

In a test with 18 mixed receipts, LedgerShield parsed line totals and vendor details in under three minutes, eliminating manual spreadsheet entry and earning positive user feedback for potential paid usage.

工作流

• 1. User drags and drops mixed receipts into LedgerShield’s web dashboard.
• 2. The local Python backend loads an open‑weight vision‑language model to process each image on the user’s device.
• 3. The model extracts vendor name, date, total amount, taxes, and category.
• 4. Extracted data is stored in a lightweight SQLite database and exported as CSV or JSON.
• 5. Users review and optionally export the structured data for bookkeeping.
