Monica is an open-source personal relationship management (PRM) web application for documenting your life and staying on top of important details about friends, family, and other relationships. It works like a CRM, but designed for personal use and private record keeping.

Key Features

• Contact management with notes, important details, and custom fields
• Relationship mapping between contacts
• Reminders, including automatic birthday reminders
• Activity and interaction logging, plus task tracking
• Address and communication channel management for each contact
• Diary/journal to record daily events and how your day went
• Document and photo uploads associated with contacts
• Labels/favorites to organize and highlight key people
• Multi-user and multi-vault support for separating data
• Multi-language interface and configurable types (e.g., activities, genders)

Use Cases

• Keep a personal “CRM” for family and friends to remember key dates and life events
• Track interactions and follow-ups for networking and long-term relationships
• Maintain a private life log combining journaling with contact history

Limitations and Considerations

• Not a social network and does not provide social posting or feeds
• No built-in AI assistant features or automatic suggestions

Monica is well-suited for individuals who want a structured, private system to organize relationship information and day-to-day memories. It focuses on simple, intentional tracking rather than social or automated behavior.
