What you'll accomplish
By the end of this guide, you'll know how to use Claude (an AI writing assistant) to draft a professional insurance supplement letter in 10–15 minutes instead of 45–90 minutes — or instead of paying $50–150 to outsource it. You'll also have a reusable template you can adapt for any job.
What you'll need
- A free Claude account (claude.ai — sign up with your email)
- The insurance adjuster's original damage estimate or scope of work
- Your own notes or CompanyCam photos of damage items the adjuster missed
- Time needed: 30–45 minutes first time; 10–15 minutes after you have a system
- Cost: Free (Claude free tier works; Claude Pro at $20/mo gives longer documents)
How-To Guide: Write Insurance Supplement Letters with AI
Step 1: Get Your Account Ready
Go to claude.ai and click "Sign up" — use your email or Google account. The free version handles supplement letters well. If your letters are very long (10+ pages of scope), Claude Pro ($20/mo) handles more text at once.
What you should see: A clean chat interface with a text box at the bottom.
Troubleshooting: If Claude says the document is too long, break your adjuster scope into sections and submit in pieces.
