Built a full business AI model for our family's 40-year-old textile machinery factory using Claude Code.
Here is what it does: - Reads two company Gmail inboxes for customer inquiries - Generates complete quotations with machine specs and actual photos pulled from our archive - Creates bills, delivery challans, and sale tax invoices from purchase orders - References 10+ years of business history (organized bills, POs, and records from 2013-2024) - Drops everything in draft email for review before anything is sent - Synced to GitHub so it runs on any device including mobile The whole thing is file-based. Context folder holds business info, rules define tone and document formatting, reference files hold templates, and the data folder holds all past records by year and month. Quotations that took hours now take seconds. The knowledge lives in the system now, not in someone's head. Happy to answer questions on the structure or how the file system is set up if anyone wants to build something similar.
