What they did
A contractor sent him a 50+ page itemized insurance estimate that had jumped $150K. Grok Bot went through it line by line and found duplicate charges, $65K of work that had been removed but never credited back, and cabinets priced at double what Home Depot quoted him. It turned it all into a simple list of questions for the contractor. It also found an EPA test report showing a $2,200 pellet stove is the same stove, from the same factory, as the $4,100+ model they recommended.
How it went
A line-by-line review with duplicates, missing credits and overpriced items, plus questions for the contractor.
Worth knowing
- One person's X post, quoted from his notes. Contractor pricing often includes labor and overhead that retail prices don't, so treat the comparison as a starting point for questions, not proof of fraud.
Prompt
Cleaned version rewritten from the source — not a direct quote.
Here is my contractor's itemized estimate: [PDF]. Go through it line by line. 1) Flag duplicate line items. 2) Compare it with the earlier version: [PDF], and list any work that was removed but not credited. 3) Check prices for big items like cabinets and appliances against [stores] and flag anything far above retail. 4) For any recommended product, look for the same model sold under another brand. 5) Give me a plain list of questions to bring back to the contractor.
