-TaxHacker is a self-hosted accounting app for freelancers and small businesses who want to save time and automate expences and income tracking with power of GenAI.

You can also create your own custom fields to extract with your LLM prompts.
+TaxHacker is a self-hosted accounting app for freelancers, indie-hackers and small businesses who want to save time and automate expences and income tracking with power of GenAI. It can recognise uploaded photos, receipts or PDFs and extract important data (e.g. name, total amount, date, merchant, VAT) and save it as structured transactions to a table. You can also create your own custom fields to extract with your LLM prompts.
 
 It supports automatic currency conversion on a day of transaction. Even for crypto!
 
 Built-in system of filters, support for multiple projects, import-export of transactions for a certain time (along with attached files) and custom categories, allows you to simplify reporting and tax filing.
