Additional notability info

I maintain InvoiceFlowAI and am submitting it for maintainer evaluation.

The application is Apache-2.0 licensed, has 301 GitHub stars, and provides current Windows x64 and macOS Apple Silicon installers. Python is the repository's primary language and implements the mailbox, invoice-processing, OCR, classification, and reporting workflow.

Its identifiable niche is Chinese electronic-invoice collection and reimbursement preparation: it handles PDF, OFD, XML, and selected invoice download links from QQ and 163 mailboxes, then produces categorized files and an Excel summary. Low-confidence results remain available for human review rather than being presented as accounting or tax conclusions.
