Bing Copilot and Perplexity are interactive AI search systems that provide answers in a chat-like interface and can be controlled by follow-up questions. Both combine a language model with a search index and generate answers dynamically based on the question asked.
AI Overviews, on the other hand, are static results in Google Search. They are automatically generated for certain search queries and only change when Google re-evaluates the content or sources, but not through direct interaction with the user.
