Monica is a personal CRM (PRM) designed to help you keep track of the people in your life—family, friends, clients, or colleagues—by storing contact details and the history of your interactions. It focuses on relationship context: notes, activities, reminders, and life events, so you can follow up thoughtfully and consistently.

Key Features

  • Contact profiles with structured fields (contact info, relationships, important dates)
  • Interaction/activity logging to record meetings, calls, messages, and notes
  • Reminders for follow-ups and key dates (e.g., birthdays, anniversaries)
  • Relationship management (link people together and track how they are connected)
  • Tagging and searching to organize contacts and quickly retrieve context
  • Multi-user support for shared instances (useful for teams/households)
  • Import/export capabilities (for migrating contact data)

Use Cases

  • Maintain a personal address book with rich context and interaction history
  • Track client/stakeholder relationships and follow-ups outside of a sales CRM
  • Keep family/household knowledge (important dates, preferences, and notes)

Limitations and Considerations

  • Oriented to relationship tracking rather than sales pipelines/forecasting typical of full sales CRMs

Monica is well suited for anyone who wants a lightweight, structured way to remember details, log interactions, and set reminders around relationships. It fills the gap between simple contact lists and heavy sales-focused CRM platforms by emphasizing personal context and continuity.
