Lesson 2 of 5 · 6 min read · Beginner

Explain a difficult concept, then brainstorm ideas

Get a hard idea explained at the level you choose, then use the model as a fast, tireless idea generator. One is about clarity, the other about quantity, and both are free-tier work.

In this lesson you will

  • Ask for an explanation pitched at a specific level with a concrete example
  • Generate a long list of ideas quickly and filter them yourself
  • Tell the difference between an explanation you can check and one you cannot

A chat model has read more explanations of compound interest than any teacher alive, and it is patient in a way no person is. That makes it a very good explainer of well-understood things. It also has no shame, which makes it a very good brainstormer: it will give you twenty ideas without worrying that fifteen are bad. Your job is the filtering.

Win 3: explain a difficult concept

Say the level ("to a 12-year-old", "to someone who has never invested"), ask for one everyday example, and cap the length. Without a level, the model aims at the middle and pleases nobody.

Try it

Explain compound interest to a 12-year-old

  • Did it work? Read the example and check the arithmetic yourself. If it says $100 at 10% becomes $110 then $121, that is right. If the numbers do not add up, the explanation is wrong even though it reads well.
  • If not: ask *"Show the calculation for each year in a table."* Making the model show its working is the fastest way to catch a slip.

Win 4: brainstorm ideas

Ask for more ideas than you want, with constraints. Ten ideas under a budget is a better prompt than "any ideas?" because the constraints do the filtering before you have to.

Try it

Ten birthday ideas under a budget

Three free runs a day on the site key. Add your own key for unlimited runs.
  • Did it work? Ten ideas, each with a cost, none a surprise party, none for a crowd. If it suggested a surprise, it ignored a constraint — worth knowing, because it will do the same with your constraints.
  • Then: reply with *"Combine 3 and 7, and give me two more like 5."* Brainstorming is a conversation, and the second turn is where the good idea usually appears.

Your turn

Your turn: a brainstorm with constraints

Give me [NUMBER] ideas for [WHAT]. Constraints: [CONSTRAINTS]. One line each, numbered, with a rough cost in brackets.

Hint: Ask for more than you need. The extra ones are cheap and the filtering is the useful part.

Lesson FAQ

Can AI explain things better than a search engine?

For a well-understood concept, often yes, because you can set the level and ask follow-up questions. For anything recent, local or niche, a search engine gets you the primary source and the AI may not. Use both: ask the AI to explain, then check the facts on a real page.

How do I get better brainstorm ideas?

Add constraints and ask for more than you need. Budget, audience, things to avoid, and the number of ideas all sharpen the output. Then treat the first list as a starting point and ask for variations on the ones you like.

Is brainstorming with AI cheating?

It is a list of options that you then choose from, the way you might ask a friend. The judgement — which idea fits your neighbour, your budget, your Saturday — is still entirely yours, and the model cannot do that part.
