Dynamic Chat

Cortex’s Dynamic Chat automatically selects the most suitable model for each prompt. Ask for a weekend itinerary and it favors planning; paste a code snippet and it leans toward execution-ready tools. Answers feel tuned to the task, so you don’t waste time switching models.

Voice Chat

Voice Chat delivers natural, real-time conversations even without connectivity. Commuting, cooking, or walking, speak instead of typing and keep ideas moving. In Cortex, replies arrive quickly and the back-and-forth feels conversational, making everyday requests faster and more comfortable on mobile.
