About

Brief Note

Features
Read full description

Sometimes you are about to meet someone and cannot quite remember the last conversation. Brief Note is a local relationship notebook that brings the context back before you meet. 1. Add one person you want to remember. 2. Write one important line after you meet. 3. Scan the briefing before the next conversation. Pin the detail you never want to miss. Optional calendar briefings can remind you on the morning of a meeting. Event titles are matched with saved names entirely on your device. Your names and notes stay on your device, not in an account or content server. When choosing a contact, only that person's name is saved—never phone numbers, email addresses, or the full address book. Export a JSON backup whenever you want and restore it by replacing or merging local data. Store up to five people for free. Adding a sixth requires a one-time lifetime purchase, not a subscription.
