The new Assistant is ready, and it's time to move! Press the button to get started.
Move to the new Assistant
We've rebuilt Assistant with a cleaner layout, better organization, and several workflow improvements. This move is permanent and will bring your existing threads with you.
Your threads will be moved to the new experience automatically.
What's changing
Tags are now folders
Your existing tags will become folders. Threads can now belong to one folder at a time, so threads with multiple tags will be organized into a single folder during migration.
New Assistant settings
Assistant now includes more settings, including a wider layout that’s especially useful when working with code snippets.
Better everyday workflow
Preview attachments, use assistant more comfortably on mobile, quote selected text directly into your next instruction, and much, much more!
