That would be currently possible with a combination of AI and standard computing.
- Have a camera on all the places you store food, let AI analyze it to tell you what's missing.
- Do some standard web scraping for prices.
- Use some clever algorithm to calculate the route (might not be always optimal, but there are some good algorithms for the travelling salesman problem).
- Let a LLM write some bullshit around the data to appear human.
