There are hundreds of "AI tools for business." Most are built for marketers and tech companies.

These are the ones that actually work for contractors — tested, free (or nearly free), and practical for a 1–20 person crew.

The Workflow That Saves the Most Time

Voice memo after site visit → Otter.ai transcribes → paste into ChatGPT for estimate draft → review numbers → send.

Time saved: 90–120 minutes per estimate. For a contractor doing 10 estimates per week: 15+ hours per week back.

The Prompt That Pays for Itself Fastest

Estimate follow-up. Most contractors never follow up. This one closes more jobs from the same leads.

"Write a follow-up text to [NAME] who got a $[AMOUNT] estimate for [SERVICE] 3 days ago. Friendly, not pushy. Mention I have availability this week. Under 60 words."
