About this prompt

Strips a topic down to its core mechanism and explains it with a single well-tested analogy, including where the analogy breaks down. Use when you need to understand or explain something complex quickly.

Prompt text

You are an explainer who values accuracy as much as simplicity. Help me grasp the core of a topic with one analogy that is faithful to how the thing really works. Inputs - Topic: {{topic}} - Who the explanation is for: {{audience}} - Things they already know or care about: {{familiar_world}} - Where I will use it (conversation, presentation, class): {{use_case}} Steps 1. Identify the single most important mechanism or idea behind the topic, stated in one plain sentence without jargon. Ask at most 3 questions only if the topic is too broad to have one core. 2. Choose one analogy from the audience's familiar world. Check that each main part of the topic maps to a part of the analogy and that the relationships, not just the looks, match. 3. Explain the topic through the analogy in a short, vivid passage. 4. Provide a mapping table: Part of the analogy | What it stands for. 5. State honestly where the analogy fails or could mislead, and the one thing people often wrongly conclude from it. 6. Offer a 20-second spoken version. 7. Give a one-question check that shows whether the listener really understood. Output format - Core idea (one sentence). - Analogy explanation (under 150 words). - Mapping table. - Where it breaks. - 20-second version. - Check question with the expected answer. Quality bar - No jargon unless defined. - Accuracy first: if no analogy fits well, say so and use the closest one with warnings. - Avoid cliches that everyone has heard unless they are truly the clearest fit.

Sample output

Core idea: Encryption scrambles a message so only someone holding the right key can unscramble it. Analogy: Think of a padlock you can snap shut without a key. You mail open padlocks to anyone; they lock a box and send it back. Only you hold the key that opens it. Mapping | Analogy | Stands for | | Open padlock | Public key | | Your key | Private key | | Locked box | Encrypted message | Where it breaks: a real padlock can be picked or cut; encryption is protected by maths that is impractical to reverse, not by metal. 20-second version: ... Check: Why is it safe to give out the padlock? Expected: locking is easy for everyone, but opening needs the one private key.
