Use AI to Explain How Websites and Apps Work

Every app and website has tech behind it. AI can explain how stuff works in language a 9-year-old gets. Great way to feed curiosity.

Some examples

• 'Explain how YouTube knows what video to recommend next, like I am 9.'
• 'How does Instagram know my friends?'
• 'How does my phone know my face?'
• 'How does the internet send a message from my phone to my friend's phone?'

Try it!

Pick one app you use every day. Ask AI to explain how it works behind the scenes. Be amazed.

Making sense of how apps really work

Every app you use has hidden machinery running behind it. When you open TikTok and it instantly shows you a video you love, that's not magic — it's a recommendation algorithm that tracked what you watched, predicted what you'd like, and retrieved the right video from millions of options in less than a second. AI can explain all of this at whatever level you're ready for. You can start with 'explain it like I'm 9' and gradually ask for more detail: 'Now explain it a little more technically.' This adjustable depth is one of AI's most powerful learning features. You're not stuck reading an explanation written for one specific skill level. You can have a conversation that starts at 'here's the simple version' and ends at 'here's how a real engineer would implement it.' That kind of progressive depth used to require a patient mentor. Now it's available to anyone with an AI.

• Start simple: 'How does [app] know what to show me?' — get the friendly version first
• Go deeper: 'Now explain it more technically' — AI adjusts to your new level
• Get specific: 'What's the actual code structure behind a recommendation algorithm?'
• Connect to your code: 'Could I build a tiny version of this? Where would I start?'
