Tree Notebook vs wispey

Tree Notebook is a hierarchical notes manager designed for keeping personal information. Tree Notebook runs on an iOS device (iPhone or iPad). Besides, there is a counterpart for OS Windows which can be synchronized with up to three iOS devices via a local Wi-Fi network. No access to Internet is needed for synchronizing. The data in Tree Notebook is divided in two parts: the public part accessible without password and the encrypted private part which requires password for opening. The data in every part is arranged as a tree-like multilevel hierarchy of folders and notes. Any folder can include notes and other folders, and so fourth. Any item (a note or a folder) can include text of any size. The items can keep attachments like images or other files. The app can represent data in several ways: as a tree, as a list of items (folders and notes) on the current level, as a list of manually selected items ("Favorites"), or the items visited recently ("History"). The contents of an individual item can be viewed or edited. Tree Notebook includes powerful search facilities: simplified or conditional global search, local search inside an item text. The items can be sorted by several criteria: alphabetically, by creation or modification time, and in manually defined order. The item titles can be attributed using a variety of font types, colored flags, graphic icons. Any item can have an Event attribute and serve as an alarm clock or reminder. A calendar feature is available to help managing events. The app is free to use both on iOS devices and desktop PC.

Thoughts fade in seconds. Catch them. Research shows most fleeting thoughts vanish within 18 seconds. wispey is built for that narrow window — open the app or tap the Lock Screen widget, and just write. No folders to pick, no titles to type. Your mind organizes nothing. Let AI do it. Every memo is automatically sorted into categories like To-do, Schedule, Ideas, and more — powered by on-device AI. You never decide where something goes. That means less friction, and science says less friction means you actually write things down. Schedules and to-dos go where they belong. When wispey detects a date or task, it routes the memo to the right place automatically — calendar events land in Apple Calendar, action items become Apple Reminders. "Design review tomorrow at 2 PM" appears on your schedule; "Cancel gym before Friday" shows up in your reminders. Flip the toggle once in Settings, and wispey handles the rest. Nothing leaves your device. Ever. All AI processing happens entirely on your iPhone using Apple Intelligence. No servers, no cloud AI, no data collection. Passwords, personal notes, half-formed ideas — write anything without a second thought. Your memos are yours alone. Multi-device, without the compromise. Privacy-first apps often mean your data is stuck on one device. wispey syncs through your personal iCloud — not our servers. Your memos follow you across iPhone and Mac, encrypted by Apple, controlled by you. Turn it on or off anytime. Save anything, from anywhere.
