Cortex Chat is the assistant for research, writing, and everyday questions. It streams answers as they are written, keeps documents and threads together in projects, and hands off to Code or Bot when the job is a repository or a computer rather than a conversation.
A Cortex Chat thread with a reply in the conversation pane

A Chat thread. The reply carries Copy, Listen, and feedback controls; the header offers Start a plan and Move to project.

The sidebar

The composer

  • + opens Attach file, Image, and Check origin.
  • The model chip (for example Cortex 1 Mini · Preview · Thinking Low) switches model, sets the Thinking level, and toggles Deep Research.
  • Enter sends; Shift + Enter adds a line; Esc stops a response.
  • While a turn runs, the placeholder reads Cortex is responding… and the send button becomes a stop control.

Home starting points

The four cards on Chat home are shortcuts, not separate products:

​
A thread

Every reply carries Copy, Listen (when voice is available), and thumbs up / down. The thread header offers Start a plan — turn this conversation into a task list — and Move to project. Replies render markdown: headings, tables, and syntax-highlighted code blocks with their own Copy button. A small line under the composer reminds you that Cortex is an AI and can make mistakes.

​
When to switch

Chat does not run Code’s workspace shell or Bot’s computer. Chat’s Python tool is a snippet sandbox with no workspace; it cannot see a repository. How the loop runs: How Chat works.
