Billly

What it does

Billly is the bookkeeping app for freelancers that runs in the background. Pick a folder, paste your OpenAI token once, and you’re done. Billly watches for new PDF invoices, extracts values via OCR + AI, and keeps revenue, expenses, and profit up to date automatically, no spreadsheets, no manual tagging, no “setup rabbit holes”.

Billly v0.3.2 is a macOS app for freelancers that turns invoices into structured data, CRM entries and Gmail follow-ups with OCR and AI.

Drop invoice PDFs into a folder. Billly turns them into a searchable invoice database, a lightweight CRM, and ready-to-send Gmail follow-ups without forcing you into a bigger system. Billly is free. OpenAI usage is billed by OpenAI and powers extraction, auto-tagging, CRM enrichment, and template filling. Gmail messages are sent from your connected account. Billly handles the repetitive classification and turns invoice files into something useful. Track incoming invoices and outgoing bills in dedicated flows from day one. Revenue invoices become customer records and reusable placeholder data. Billly now closes the loop from invoice extraction to customer communication. Billly can send…from oliverjessner.at

  I spent 3 years reverse-engineering a 40 yo stock market sim from 1986▲721

  Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
