You can use Flux without an account, but signing up for free unlocks chat history, bookmarks, and a higher daily message limit.

Guest vs. signed in

You can start chatting immediately without creating an account. As a guest, you get:
  • 10 messages per day — resets every 24 hours
  • No chat history — conversations are not saved between sessions
  • No bookmarks — you can’t save helpful responses for later
Guest usage is tracked in your browser. If you clear your browser data, your daily count resets.

Daily message limits
