What it is
TaxHacker is a self-hosted accounting app designed to automate expense and income tracking using AI. It accepts photos of receipts, invoices, or PDFs, extracts data (dates, amounts, vendors, line items), and stores it in a structured database. It supports custom fields, categories, projects, and AI prompts for extraction.
How it works
Users upload or snap documents; the app uses AI to extract key fields, categorize transactions, and store data in a database. It includes multi-currency support with historical exchange rates, and can use local or external LLMs (OpenAI, Gemini, Mistral, or self-hosted options). It offers full-text search, advanced filtering, and export capabilities. The self-hosted mode provides data privacy with local storage and a Docker-based deployment.
