Nomen is your personal memory assistant. It helps you remember people, conversations, and important details simply by talking naturally to your phone. Inspired by the ancient Roman nomenclator, Nomen acts as your digital brain. You tell it things as they happen, and later you ask questions to recall them. No folders. No manual tagging. No effort. Just conversation. Save memories by typing or speaking exactly the way you think. • “Had lunch with Sarah. She mentioned her new job at TechCorp.” • “Mom’s birthday is next Thursday. She wants the blue cashmere sweater.” • “Project Alpha deadline is May 1st. Need two more engineers.” Nomen understands context, extracts important details automatically, and stores everything for you. Ask natural questions and get clear answers drawn from your own memories. • “What did Sarah say about her job?” • “When is Project Alpha due?” • “What does Mom want for her birthday?” Follow-up questions work seamlessly. Pronouns and references are understood just like in a real conversation. Nomen automatically recognizes people, places, companies, dates, and topics. It builds entity profiles behind the scenes so your memories stay connected over time without any manual work. Browse memories, search instantly, edit or delete anything. You stay in full control.
