PaperLine is an expense tracker built around trust in the numbers. Raw invoice data is never overwritten by currency conversion, and every change is logged with who made it, so nothing gets silently altered without a trace. It extracts text directly from each invoice first, and only sends it to a vision model when that extraction isn't enough, keeping it cheaper and faster than tools that run every document through a vision model. Built with Expo/React Native, FastAPI, and Supabase.
