AI-native expense intelligence vs developer-focused manual tracker.
Lunch Money relies on rules-based auto-categorization that you configure manually. PennySlice's RAG-powered AI categorizes transactions automatically and learns from every user's corrections across the entire community.
Lunch Money is a dashboard-first tool. PennySlice lets you ask questions in plain English across 8 specialized AI engines. "How much did I spend on dining?" gets a real answer, not a chart to interpret.
