TaxHacker: AI Reads Your Receipts
TaxHacker is a self-hosted AI accounting app that turns receipt photos and invoice PDFs into structured records. Upload a document, let an LLM extract the merchant, total, date, and currency, then manage everything in a spreadsheet-like view. Supports OpenAI, Gemini, Mistral, and local models via OpenAI-compatible endpoints.

The story
What the video said
You want to turn a pile of paper receipts into clean digital records, but typing every merchant, total, and date by hand takes hours and you keep making mistakes. You need a faster way to get all that paper into a spreadsheet you can actually use.
TaxHacker is an open source accounting app you can run on your own computer. You upload receipt photos or invoice PDFs, and it uses AI to read them and save the details. It works with OpenAI, Gemini, Mistral, or a local model.
When you upload a file, TaxHacker builds a prompt and sends it to the AI model you picked. The model returns structured data like merchant, total, date, and currency. You can add your own custom fields with their own prompts.
In the demo, you see an uploaded invoice with the merchant, total, and currency already filled in. A saved transaction shows the raw text the AI read. Your receipts become a searchable table you can filter and export.
