Getting Useful Answers

Prompting, in three habits

Be specific about the output

"Write a one-paragraph summary for a non-technical reader" beats "summarise this." State the format, length, and audience.

Give it the context it's missing

The tool doesn't know your situation unless you tell it. A sentence of background changes the answer more than a clever phrasing trick.

Ask it to show its reasoning

For anything with real stakes, ask it to explain how it got there — it surfaces mistakes you'd otherwise take on faith.

Verify before you rely on it

Treat a confident-sounding answer as a draft, not a fact — especially for numbers, dates, and anything you'd cite elsewhere.

Selection method

Why these tools are here

I deliberately keep this page smaller than a typical “100 AI tools” directory. A beginner benefits more from understanding a few useful categories than from scrolling through dozens of logos. Each entry should answer three things: what the tool is particularly useful for, where it can disappoint, and who should try it first.

Provider claims are not treated as independent proof. When a feature can be checked directly, I use the product itself or its documentation; when that is not practical, I say what the recommendation is based on rather than implying first-hand testing.
