NanoClaw - AI Agent on Raspberry Pi
NanoClaw is an open-source, secure AI agent framework (~3,900 lines across 15 files) that I deployed on a Raspberry Pi 3 collecting dust in a drawer. It runs as a Discord bot with a distinct personality, scanning grocery receipt photos, extracting every line item (merchant, quantity, price per kg, total), and storing everything locally in SQLite. No cloud. No subscription. Send a receipt photo on Discord and she replies with witty commentary like 'Two kinds of onions and two bags of rice - you were PREPARING for something' while quietly building a price-per-kg database across every shop. It tracks most-bought items, spending patterns, hall-of-fame moments, and acts as a personal inflation tracker built from actual receipts, not government averages. Costs ~$1/month to run. Your data never leaves your desk.
