LedgerVault AI: Privacy-First Expense & Tax Auditor for Freelancers

LedgerVault AI and Ledgerling are local-first expense tools created for the Hacktoberfest Open-Source AI Challenge. Freelancers and solopreneurs often spend hours monthly on tax write-offs while facing privacy risks when using cloud AI services like OpenAI or Anthropic due to NDAs. Ledgerling utilizes a local Gemma model to extract merchant, date, and total data from receipts. This prototype allows users to manage a browser-based ledger and export CSV data without using hosted services.
