What AI can do

Today's AI is strong at drafting, summarizing, brainstorming, translating, and converting between formats. It is weak at knowing your facts, doing arithmetic reliably, and exercising judgment about people. The right mental model is a fast, tireless junior assistant with broad general knowledge and no access to your books, your customers, or your reputation. So use it where a wrong first draft is cheap and a human review is guaranteed. A common mistake is treating a confident-sounding answer as a verified one. AI tools are built to produce fluent text, and fluency is not the same as accuracy. The most damaging errors happen when a busy owner skips the review step because the draft reads smoothly, not because it was actually checked against real facts about the business, the customer, or the job. Deciding whether a task is a good fit means asking two questions: is a wrong first draft cheap to catch, and will a specific person actually check it before it goes out. If either answer is no, the task is not ready to hand to AI yet, no matter how much time it might save. Tasks that touch money, legal terms, or medical and safety details need a stricter standard than a first-draft email. You can judge good output from bad by checking it against something you already know is true: your price list, your actual policy, your calendar, your customer's real history. If the draft states a fact you cannot independently confirm, treat it as a placeholder, not a finished answer. When output includes specific numbers or claims, verify each one individually rather than trusting the whole paragraph at once. A small bookkeeping firm asked an AI tool to summarize a client's expense categories from messy notes, then had the bookkeeper check every category before filing. The tool saved real time on formatting, but it also miscategorized two entries that the human catch prevented from becoming a filing error. The lesson was not to stop using the tool, but to keep the review step non-negotiable regardless of how good the draft looked.

• So use it where a wrong first draft is cheap and a human review is guaranteed.
• Drafting is cheap to check; judgment and facts about your business are not.
