FinAd is a self-hosted personal finance manager with AI-powered receipt scanning. Track accounts, transactions, budgets, and net worth — all data stays on your machine. Snap a photo of any receipt and Claude Vision extracts the amount, date, and category automatically. Runs in Docker with a single command.
The AI integration is the key differentiator: upload a receipt image and the Anthropic Claude API analyzes it via computer vision — extracting the total amount, merchant name, date, and auto-categorizing the expense. No manual data entry needed. The app also supports file attachments (images/PDFs up to 10MB) on any transaction for record-keeping.
