Top 10 Everyday Applications of Large Language Models That Might Surprise You
In 2024, over 50% of global internet users interact with some form of artificial intelligence daily, and most don’t even realise it. From powering personalised learning experiences to streamlining financial decisions, Large Language Models (LLMs) like ChatGPT, Claude, Perplexity, and Gemini are deeply embedded in our routines. A recent report by McKinsey estimates that generative AI could add up to $4.4 trillion annually to the global economy. Yet despite this staggering number, the average user is still unaware of how often these AI agents quietly assist them.
So what exactly are LLMs, and how are they surprisingly transforming your everyday life? Let’s break it down.
What Are Large Language Models?
Large Language Models are a type of AI trained on vast datasets of human language. They understand and generate human-like text, answer complex questions, summarise data, and even write poetry or code. LLMs use natural language processing (NLP) to bridge the gap between human intent and machine response.
These models power many popular apps and systems you use every day, even if you don’t know it. Below are ten everyday applications of LLMs that might surprise you with how integrated and impactful they have become.
