We’ve all been there: staring at a dropdown with 50+ options, wishing the app would just know what we want. Usually, we solve this with a heavy backend search API. But what if you could build a lightning-fast, "psychic" recommendation engine entirely on the client side? Here’s how to build a smart template recommender that anticipates user needs with zero latency. The Core Logic: Context is King 👑 Most search bars look at the whole text. To make recommendations feel intentional, we focus only on the intent.
