AI Search: Why It Matters and Why It's Rapidly Gaining Popularity

A year ago, finding a vegetarian restaurant near Asok open in the evening required typing keywords into Google and browsing through multiple links. Today, you type the same question into ChatGPT or Perplexity and receive a synthesized answer in seconds. This is AI Search — and it's rapidly changing how people around the world find information.

How AI Search Works

AI Search uses Large Language Models (LLMs) to understand questions and generate complete answers, rather than returning a list of links. It understands user intent beyond keyword matching, synthesizes information from multiple sources into a single response, communicates in natural language, and retains conversation context for follow-up questions. Leading platforms in 2025 include ChatGPT Search, Perplexity AI, Google AI Overviews, Microsoft Copilot Search, and Gemini.

Why AI Search Is Growing So Rapidly

AI Search saves significant time — users report 60–80% time savings on informational queries compared to traditional search. It handles complex, multi-part questions that traditional search addresses poorly. It supports natural conversational input rather than requiring keyword formulation. And it integrates directly into productivity tools like Microsoft 365 and Google Workspace, enabling search without leaving your workflow.

The Numbers

In 2025, AI Search adoption signals are unmistakable: ChatGPT has over 200 million weekly active users globally; Perplexity AI saw 400% query volume growth in a single year; Google AI Overviews appear in over 50% of search results; and 40% of Gen Z users report using AI Search as their primary search tool over Google.

What This Means for Thai Businesses

Customers now ask more specific, complex questions — not just keywords. Businesses cited in AI answers gain brand awareness even without clicks. And AI favors high-quality, comprehensive, trustworthy content — making content marketing investment directly valuable.
