Before Steve Jobs said another word about the iPhone, he set it up in one sentence:
"Today, Apple is going to reinvent the phone. And here it is."
That's it. One sentence. Before any specs, any features, any demos — you already knew what it meant. Not what it does (technical), but what it is (conceptual).
This is the single most powerful tool in your communication toolbox. Before you explain anything about technology or AI, you need one sentence that frames it. The rest is just detail.
Every great tech explanation starts with this structure:
A is B that lets you C
Where:
"ChatGPT is like a super-smart assistant that helps you write, brainstorm, or answer questions just by chatting."
Notice: no jargon, no architecture, no training data talk. Just the gist.
| Product | One-Sentence Framing |
|---|---|
| iPod | "1,000 songs in your pocket." |
| iPhone | "A widescreen iPod with touch controls, a revolutionary mobile phone, and a breakthrough internet communicator." |
| iPad | "A device that's far more intimate than a laptop and far more capable than a phone." |
Each one answers the question the audience is asking: "what is this, and why should I care?"
Your friend's brain is a pattern-matching machine. When you give them a familiar category ("like a smart assistant"), their brain instantly attaches everything they already know about assistants to this new thing. You've built a bridge from the known to the unknown.
If you start with specs ("it's a large language model with 175 billion parameters trained on internet text"), you've burned that bridge. Their brain checks out because there's nothing to latch onto.
What most people do:
What they should do:
Pick one of these and write a one-sentence explanation using the formula A is like B that does C:
Say it out loud. Then text it to me or just say it here. The real win is when it rolls off your tongue naturally, not when it's written perfectly.
Watch Steve Jobs introducing the original iPhone in 2007 — the first 3 minutes are a masterclass in this principle. Pay attention to how he builds up to the reveal, then nails it in one line.
Before you explain anything, ask yourself: "Can I say what this is in one sentence?" If you can't, you're not ready to explain it yet.
