Compare home repair and contractor quotes apples-to-apples with AI
Turn two or three written contractor bids into a side-by-side table so you can spot padding, missing items and red flags before you sign.
1. Copy this prompt
Paste it into ChatGPT, Claude, Gemini or Grok (the free versions work), then replace the [highlighted brackets] with your details. Leave out account numbers and SSNs.
I have [NUMBER] written bids for [JOB, e.g. replacing a 3-ton AC unit] in [CITY, STATE]. Here they are with personal details removed: [PASTE BIDS]. 1) Build a table comparing price, exact scope, materials/brands and model numbers, permits, timeline, warranty and payment schedule. 2) Flag items one bid includes that others don't, vague line items and red flags (large upfront deposits, cash only, no written contract). 3) Write polite follow-up questions for each contractor. 4) Tell me what to check about licensing and insurance and where.

What to expect, and what to do if they say no
What happened when people tried it

Why this works
The problem: Quotes for roofing, HVAC, plumbing or remodeling are written differently, which makes it hard to tell which is actually cheaper or more complete.
How AI helps: AI can normalize bids into one table (scope, materials, permits, warranty, payment schedule), flag what's missing, and draft questions to send back.
