Show HN: Payment Hunter – AI-powered invoice reminders for freelancers

2•paymenthunter01•1h ago
I freelance and got tired of manually tracking who owes what and sending follow-up emails. I built Payment Hunter (https://paymenthunter.bot) to fix this. Upload invoices (PDF or image), OCR + an LLM extracts client, amount, and due date, then automated reminder emails go out on a schedule you configure. The extraction pipeline hits ~99% accuracy on standard invoice formats. Plans from $19/mo with a 30-day free trial. Would love feedback on the approach.
