Calendar, assignments and core planning features are free. The AI assistant requires AI Standard or AI Pro. TURN A CONVERSATION INTO A PLAN Tell the AI "Essay due Friday" to create an assignment with a deadline. Type or speak to add and change events, assignments, to-dos, routines and goals. Review a confirmation before deleting events or assignments. Discuss a goal, break it into steps, or search the web with sources in the same chat. Ask it to remember useful details, then review, edit or delete them in Settings > "What AI remembers". Return to the reply after switching apps. SEE YOUR DAY A month calendar and a 24-hour circle bring your events and time blocks together. Switch to a list when you prefer. Use repeating and all-day events, labels, up to 10 alerts per event, checklists, day counters, undated notes, search and holidays in Japan. MAKE ROOM FOR SHARED PLANS Share calendars by invitation with "Can edit" or "View only" access. In-app notices show changes.

Verdict
The clearest difference is in-app purchases: Second Brain at none against ToSche's 6. ToSche's advantage is update cadence (every 2 weeks vs monthly) and iOS requirement (15.1 vs 26.0). On price, ads and device support there is nothing between them.
