TaxHacker

TaxHacker is a self-hosted AI accounting app that uses large language models to automatically analyse receipts, invoices, and bank transactions. Feed it documents or connect your accounts, and it extracts line items, categorises spending, and tracks expenses using custom prompts and categories you control.

Because it is fully self-hosted, your financial data never leaves your server. TaxHacker works with your own LLM provider or a local model, supports multi-currency and expense management, and keeps a transparent history of every analysis so you can review and correct the AI's work.

Released under the MIT license and actively developed, it is a tool for freelancers and small businesses that want AI-assisted bookkeeping without handing their financials to a third party.
