An honest worksheet. No salesman's pitch, no doomsaying — just a list of real jobs and how much you can lean on the machine for each. Sort it, search it, find your answer.
← back to the front coverThe single most useful thing to learn about AI is where the line is — what it does so well it'll amaze you, and what it does so badly it'll embarrass you (and you, if you trusted it). Below is the whole list as a working table you can boss around.
How to read the rating. Five dots means "trust it, it's terrific." One dot means "double-check every word, or don't bother." Tap any column heading to sort. Type in the box to find a job. Or hit a button to show just the safe ones, the iffy ones, or the keep-your-hand-on-the-wheel ones.
Brilliant with one hand — banana peel in the other. Know which is which.
| Drafting a letter, email, or note | ●●●●● Great | Its home run. Tell it the situation, it produces a polished draft you then make your own. |
| Explaining something in plain English | ●●●●● Great | Insurance letters, medical jargon, legal mumbo-jumbo, how a thing works — patient as a saint, never makes you feel slow. |
| Summarizing a long document | ●●●●● Great | Paste or photograph it; ask "what are the three things I need to know." Saves an afternoon. |
| Brainstorming ideas | ●●●●● Great | Gift ideas, names, dinner plans, party themes — it never runs dry and never judges a goofy ask. |
| Rewriting to be shorter / clearer / kinder | ●●●●● Great | "Make this friendlier." "Cut it in half." "Less stuffy." Instant new draft, every time. |
| Translating between languages | ●●●●● Great | Conversational, everyday translation is excellent. (For legal or medical documents, still use a certified human.) |
| Recipes & what-to-cook ideas | ●●●●○ Strong | Wonderful for "here's what's in my fridge" ideas. Sanity-check baking times and food-safety specifics. |
| Planning a trip or an outing | ●●●●○ Strong | Great for itineraries and ideas. Confirm hours, prices, and that places still exist before you drive there. |
| Teaching you a new skill or subject | ●●●●○ Strong | A tireless tutor — "explain it like I'm new, then quiz me." Verify any hard facts you'll rely on. |
| Writing a poem, toast, or story | ●●●●○ Strong | Surprisingly good and a delight for occasions. It's a starting point — your edit makes it heartfelt. |
| Reading a photo (a label, a sign, a letter) | ●●●●○ Strong | Snap a picture and ask. Strong, but blurry photos and fancy handwriting can trip it up. |
| Everyday math & budgets | ●●●○○ Iffy | Fine for setting up the approach; can fumble the actual arithmetic. Re-do anything that touches your money on a calculator. |
| Current events & "what's the latest" | ●●●○○ Iffy | It learned up to a cutoff date and may not know recent news. Some can look things up live — ask it to, then check the source. |
| Finding a specific quote, page, or citation | ●●●○○ Iffy | It can invent a real-sounding but fake source. Treat any citation as "go verify this exists." |
| Health & symptom questions | ●●●○○ Iffy | Brilliant at explaining; a terrible doctor. AI explains, doctors decide — see Chapter Fourteen. |
| Exact dates, prices, phone numbers, addresses | ●●○○○ Shaky | Its single weakest area. It may state a wrong number with total confidence. Always confirm from the real source. |
| Legal advice you'll act on | ●●○○○ Shaky | Useful to understand a document or draft a first version. Anything with legal teeth goes to a real lawyer. |
| Counting, spelling tricks, exact word counts | ●○○○○ Don't | It famously miscounts letters and words. Don't rely on it for "how many," "is this spelled right in this exact way," or puzzle-style tricks. |
| Anything where being wrong is dangerous | ●○○○○ Don't | Dosages, electrical wiring, financial bets, mushroom IDs. A confident wrong answer here costs too much. Get a qualified human. |
| Keeping a secret you typed in | ●○○○○ Don't | It isn't a vault. Never type a password, Social Security number, or card number — see Chapter Nine. |
Twenty common jobs · tap a heading to sort · ratings are this guide's honest opinion, not a guarantee — when it matters, verify (Chapter Five).
Look down the worksheet and you'll spot the pattern. AI is a five-star helper for anything about words and ideas — explaining, drafting, rephrasing, brainstorming. It's a one-star helper for hard facts and numbers — exact figures, fresh news, counting, anything where confidently-wrong does real harm.
So the rule is simple: let it do the talking, and you keep the checking. Use it to understand, draft, and explore all day long — and any time the answer becomes a number you'll spend, a fact you'll repeat, or a decision that bites if it's wrong, put a human (or an official source) in the loop. That's the whole skill, and now you've got it.
