You do not need to understand how these tools work to use them well. You need to know what they are good at, where they fall down, and what never to paste into them.
Drafting: emails, summaries, cover letters, first versions of anything. Explaining: paste a confusing contract clause or error message and ask for plain English. Rewriting: "make this shorter", "make this friendlier", "make this sound like me". Brainstorming: ten names, ten angles, ten questions to ask. These jobs play to the tools' strengths because you can judge the result yourself.
Facts. A chatbot states things with the same confidence whether it knows them or invented them. Numbers, dates, legal rules, medical questions, anything current: verify before you rely on it. They also cannot know your company's private context, and they will guess instead of saying "I don't know".
ChatGPT, Claude, Gemini and Copilot all have free tiers that handle everyday tasks. Perplexity is useful when you want an answer with links to sources you can check. Try the same task in two of them and keep whichever answer is better.
Never paste passwords, ID or social security numbers, bank details, client data, or unpublished company financials. Assume anything you type could be read by someone you did not intend. When in doubt, strip names and numbers before pasting.
Treat every answer as a first draft from a fast, confident intern. Read it, fix it, check the facts that matter, then send it. Used that way, these tools save real hours. Used blindly, they make you look careless at scale.
