Can AI help me hire a contractor?
Half. It can compare bids you paste, list questions to ask and flag red flags in a contract. It can't verify licenses, insurance or reviews for you; check those with your state and past clients.
01Why half-bot
- Bid comparison and question lists are strong AI uses.
- License and insurance checks need official sources.
- It helps you spot vague scopes and big upfront payments.
02The prompt
