General information only
Everything here is my own experience and opinion, shared for general information. It isn't legal, financial, tax, accounting, engineering, safety, insurance or IT advice, and reading it doesn't create any professional relationship.
Your situation is different
Check with your own professionals before you change how your business handles contracts, money, data, people or safety.
Keep sensitive information out
Don't put passwords, bank or card numbers, employee personal information, anything a customer or builder would want kept private, or your pricing into an AI tool unless you know your setup protects it and your company allows it. When in doubt, take the names and numbers out first.
Read your AI tool's terms and your company's rules
Every AI provider has its own terms of service and data policies, and they change. Read them, and follow your employer's policies, before you put any work information into an AI tool.
AI makes mistakes
Check every output, especially numbers, contracts, specs and anything that goes to a customer. You're responsible for what you send.
What I share here
I take out or change names, prices and details that could identify a person, customer or company I work with. The stories are real, and the time I got back is my own honest count. Yours will be different.
My views only
What I write doesn't speak for any company I work for or with.
Things change
Tools, features and policies change fast. What I describe was accurate when I wrote it and may not be later.
No paid endorsements
Nobody pays me to mention their product, and I don't use affiliate links. If that ever changes, I'll say so right in the post, not just here. Product names belong to the companies that make them. None of them sponsor me or have any say in what I write.
Use at your own risk
Everything here is shared as is, with no promise that it's complete, current or right for your situation. To the fullest extent the law allows, I'm not responsible for any loss, or for any decision you make, based on what you read here.
Your privacy
I collect as little as I can, and I don't sell your information. Signups and the Tuesday emails are handled by Substack, under its own terms and privacy policy. The signup box on this site is Substack's too. This site counts visits with Cloudflare Web Analytics, and Cloudflare says it doesn't use cookies. I don't add any other tracking. If you email me, I only use your address to write back. Every Tuesday email has an unsubscribe link. You can also email me anytime to ask what I have or to have it deleted.
Using what I write
Read it, share it and link to it. Quote a few lines with a link back. Don't copy whole posts, republish them or sell them without asking me first. The name A Concrete Guy in AI, the logo and the posts are mine.
