How does an AI shopping expert actually work?

You tell it you want a compact vacuum that doesn’t sound like a jet engine.
Seconds later, you’re scrolling through a shortlist that somehow understands your apartment’s scale, your noise tolerance, and your budget ceiling.

It feels intuitive, almost psychic — but what’s really happening when an AI shopping expert “gets you”?

It’s not magic. It’s math — and memory.
An AI shopping expert reads the same product pages you do, but faster. It scans thousands of listings, specs, and reviews to build a structured map of features (“quiet,” “cordless,” “battery life,” “under $300”).

Then it learns your preferences through signals — what you click, compare, or linger on. Over time, it starts making probabilistic bets: “If you liked this, you’ll probably like that.”

How it actually works

1. Data digestion: Parses specs, prices, and reviews to understand product attributes.

2. Pattern learning: Uses models like collaborative filtering and transformers to find hidden connections between items.

3. Contextual reasoning: Reacts in real time; even a small pause or revisit can change future suggestions.

4. Privacy filters: Modern systems use federated learning, keeping your data local and encrypted.

5. Language models: LLMs interpret your natural-language prompts into structured filters (“quiet, compact vacuum under $300”).

Why it feels personal

Because it’s built to notice the right kind of details.
Your recent sessions, favorite specs, and avoidance patterns all blend into a dynamic taste profile that updates as you shop.

The trade-off

Personalization saves time but can narrow your world.
Ethical systems (like Marty) include transparency, bias control, and reset options so you can see why something appeared — and fix it when it doesn’t fit.
