Your first chat

The first time you open Cortex, it asks how you want to use it today: I just want to talk (questions, writing, ideas) or I'm going to code (the AI works on the files of a project). You can switch at any time.

  • On phones, the chat takes up the whole screen. Tap the » button at the top (or swipe from the left edge) to open the chat list along with the shortcut column; tap outside to close it.
