Notes and files stay in this browser unless you explicitly copy, print, or download them. Browser storage can be cleared by private mode, site-data cleanup, or browser settings, so export important notes.
Limit presets & publish-ready trim
Switch between common writing budgets, see how close the current text is to the limit, and create a trimmed copy while keeping the editor unchanged until you choose to apply it.
