Promptly is a notes app built around one field. Write a line and it files itself where you left off, or send it elsewhere with @notebook and #topic as you type. Pull down and you're in the notebook. Topics connect notes across notebooks, the timeline shows every day at a glance, and Ask answers from your own notes using Apple's on-device Foundation Models. Turn any notebook or topic into a prompt for any AI, names swapped out. Works with Siri and Shortcuts. No account. Free, with one-time Pro.
