Chatting
- Start a chat. Type in the box at the bottom and press Return. Press Shift Return for a new line. ⌘K starts a new chat.
- Stop a reply with the stop button or Esc.
- Edit or retry. Hover over your message and click the pencil to change it, or use the retry button under a reply. Every version is kept: switch between them with the ‹ 1/2 › arrows.
- Think harder. The brain button asks for a more careful, step-by-step answer, which is useful for math and tricky questions.
- Incognito chats (in the sidebar) are never saved and never read or write memory.
- Find old chats with the search box in the sidebar. It searches inside messages too.
- Export a chat as Markdown, JSON or PDF with the download button at the top right.
- Light or dark. Pick a theme at the bottom of the sidebar, or follow your Mac’s setting.
