Track pantry stock from receipts and buy groceries
A custom AI system reads receipts, estimates kitchen stock, checks grocery store availability and prices, buys groceries, and suggests recipes.
- What They Did
- User ingests receipts and spending data into a custom service, then exposes a grocery budget envelope plus recipe history and financial data to a stock estimator tool. A second tool connects to local grocery store APIs for nutrition, availability, and prices. Both tools are exposed over a terse MCP surface to an AI harness (ChatGPT plus opencodev2) that produces stock updates, budgeting, and recipe recommendations.
- How It Went
- The system genuinely saves the user time and money through ongoing stock estimates and recommendations. No purchase execution or quantitative results are stated.
- Worth Knowing
- User offered to open-source the stack if others want it.
Try it yourself with custom-built or unnamed agent
In the folder [path to receipts] I have grocery receipts. Read them, build a running estimate of what's in my kitchen, and save it as [pantry file name]. Then list what I'm likely low on, suggest [number] recipes using what I have, and prepare a shopping list. You are done when the pantry file and shopping list exist; don't buy anything without showing me the list first.
