Perplexity (AI Search)
An AI search service: write your question as a sentence and it looks things up on the web and returns an organized answer. Below the input box you can choose a search mode and which model to use, and there is a voice input button. The left menu has Spaces, Artifacts, and History for revisiting earlier sessions.
How to try it
Type what you want to know in the "What do you want to know?" box in the middle and send it. Pressing "/" in the box brings up search modes and "@" brings up connectors. The interface supports Korean, and a cookie consent dialog appears on your first visit.
