What is an AI search engine?
An AI search engine uses artificial intelligence to understand queries, rank results, and generate answers based on relevance and context. It goes beyond keyword matching by analyzing intent, semantics, and user behavior to deliver more accurate and personalized results than traditional search engines.
The current AI search engine landscape
The AI search engine market in 2025 has become increasingly competitive, with established tech giants and innovative startups vying for dominance. According to FirstPageSage's market share report from April 2025, the landscape shows significant concentration among a few major players but with emerging competitors gaining ground.
Current market share statistics
ChatGPT remains the dominant player in the AI search market, but its growth has slowed as competitors have emerged with compelling alternatives.
The FirstPageSage report indicates that while ChatGPT maintains its leadership position, it "has seen a decline in market share this year at the hands of its many smaller competitors," particularly specialty AI tools like developer-focused Phind and business-oriented Claude AI.
